Ear Anatomy and How Sound Processing Works
Hearing is different from the sense of smell, taste, and sight because it relies on physical movement such as vibrations in the air that are picked up by
the ear which causes the eardrum to vibrate. When the vibrations carry through the middle ear, they encounter three bones that are named the hammer,
anvil, and the stirrup. These three bones work together to amplify sound waves. The vibrations move from the middle ear into the cochlea that is
known as the inner ear. The vibrations in the inner ear cause the fluids called perilymph and endolymph to move around and that is when the brain
takes notice. The movement of the fluid bends hair cells that sends signals to the auditory nerve and interprets them. Groups of neurons are decoding
every sound that is heard and arranging them to create...show more content...
The test was designed to provide information for four areas; auditory attention (the optional auditory figure–ground screener presented on CD at the
start of the test session); basic phonological skills (Subtest 1: Word Discrimination, Subtest 2: Phonological Segmentation, and Subtest 3: Phonological
Blending); auditory memory (Subtest 4: Number Memory Forward, Subtest 5: Number Memory Reversed, Subtest 6: Word Memory, and Subtest 7:
Sentence Memory; and auditory cohesion (Subtest 8: Auditory Comprehension and Subtest 9: Auditory Reasoning). This test is untimed but can be
completed in about one hour. It takes about 15–20 minutes to score. It norms based on data from over 2,000 students and now nationally stratified to
match the latest US Census demographics with regard to gender, ethnicity, residence, geographic location, and parent education

Dental 101 Teeth Anatomy
Dental 101: Tooth Types And Anatomy Did you know that no other substance in your body is harder than your teeth? They are as mighty as they are
tiny–and much more complex than you think. While the appearance of your smile typically steals the spotlight, in order to efficiently carry out
essential processes such as chewing and speech, careful attention must be paid to other aspects of your teeth. From form to function, find out about
key features of your teeth that play a critical role in your oral health. Tooth Anatomy Starting from well below the gumline and up, each and every
tooth is made up of these basic parts: Root Serving as the "anchor" of the tooth, it is buried deep into the sockets of the jawbone in order to keep the
tooth securely in place. Even though it is not visible to the naked eye, the...show more content...
Similar to the root, it is centrally located, but it can cause individuals pain if exposed due to a cavity, crack or fracture. Dentin The porous layer that
covers the pulp and sits below the outer tooth enamel. Because of it secretes a mineralized substance, and is soft and flexible, it provides tooth
enamel an added layer of support and helps prevent enamel from fracturing. If the enamel is compromised and the dentin is exposed, however, it can
cause tooth sensitivity. Enamel The hard, white exterior covering of the tooth. Comprised of calcium phosphate, its hardness serves to protect the
sensitive inner parts of the tooth, but it is still vulnerable to wear and tear, injury and tooth decay. Although diet and hygiene play important roles in
keeping your teeth in good shape, crowding, bite and/or alignment issues due to genetics can also have a big impact on the condition of your teeth.
Types Of Teeth Adults normally house a set of 32 teeth that are built to serve different purposes. In general, teeth are classified into one of four

Grey's Anatomy Essay
The best television show made is any show that inspires people to follow their dream. There are many shows they were produced to do just this.
They demonstrate that no matter how different you may be or where you're from anything can be possible if you work hard enough. Motivating the
youth as well as adult population to go after a career or passion. For this reason, no one show is the greatest of all time for the entire population. Each
individual has a show that they admire and enjoy watching. This show should allow the person to forget all that's on their mind and let them escape
their reality for the short hour in which the productions airs. Grey's Anatomy is this show for me and many others around the nation. It was the first

There is always new life lesions integrated into each storyline. There is also a perspective of life and personality placed with each character.
Behind each and every scene there is a greater purpose that the producer embedded into it. This subconsciously has the watcher learn a lesson
while watching the series and having them more attached to the show. This is all within the production Grey's Anatomy. Incorporating that there is
a way for one to be successful in whatever they dream whether they are male or female, young or old, rich or poor. The message that any person
no matter who they are can do what they put their mind too even if it is a high status career. Explaining the work that it takes to get there and
obstacles they will have to overcome. With this accomplishment of a great career due to their hard work it is also possible for them to have great
relationships and family life outside of work. Grey's just as any other well created series can help sculpt the minds of this generation. Television is an

The Anatomy And Physiology Of The Human Body
The human body is a very complex organism composed of many systems. Each system in the human body has a specific function, and without any
of these systems working properly life can be challenging. As a result, it is important to know and understand the anatomy and physiology of the
human body. Many changes in the human body can have positive or negative effects on the overall health. The lifestyle of a person including diet,
age, gender, level of activity and more can influence someone's overall health. When something in the body is not working as predicted the human
body will have a physical or physiological response. The systems of the body have different ways of expressing themselves when they are not in
balance. As a consequence many changes come as a result of the affected system and the result can be seen in many ways. For example: when someone
notices that one extremity of his or her body is swollen or does not look the same as the contralateral side there is something to analyze. In this case,
knowing the symptoms can help with the diagnosis and the possible different treatments. Before diagnosis, and possible treatments for a condition it is
important to know the mechanisms to better treat the problem, in this case Lymphedema. First, it is important to understand the mechanisms of
Lymphedema. There are three major ways from which fluid in the body travels: the circulatory system, the interstitial spaces between the cells and the
lymphatic system. The circulatory

Anatomy And Physiology Study Guide
1.Distinguish between anatomy and physiology
Anatomy is the study of the structure and shape for the body and its parts and their relationship to one another. Anatomy is most commonly related to
gross anatomical studies because in these studies preserved animals and their organs are dissected and examined. And microscopic anatomy is the study
of body structures that can only be seen through a microscope. Physiology is the study of how the body and its parts work or function. Physiology is
similar to anatomy in a way that they have many subdivisions. Physiology has; neurophysiology which explain the function of the nervous system. It

Anatomy And Physiology Personal Statement
Throughout my undergraduate studies, I became fond of the Health Sciences field. My interests in the field came about when I first took an Anatomy
/Physiology course at New Mexico State University in the United States. In this course, I learned about different aspects of the body and how certain
diseases (infectious and chronic) can impact the body. It was then when I realized that many of the diseases being discussed in class were preventable.
I have always found the medical professions such as doctors and nurses etc. very interesting. As time has passed by, my interests have shifted more
towards prevention rather than applied medicine. Through my Anatomy/Physiology course and learning the importance of prevention, I then became

Neuroanatomy Essay
Neuroanatomy is the study of structure and function relationships in the brain and nervous system. As this encompasses a study of both macroscopic
and microscopic structures, a variety of histological tools have been developed to enable that endeavor
Microscopy
Microscopy is an important technique for studying the structure and function of the nervous system. This is enabled through the use of histological
staining, in which a tissue of interest is preserved and sectioned, and then stained using one of an array of techniques.
Histological staining provides contrast to the tissue so that details can be distinguished. For example, gray matter contains neuron cell bodies, or
somata, that can be stained to become visible under a microscope. Nissl stains are useful for gray matter. For white matter of the brain, dyes such as

Histochemistry studies can reveal the molecular interactions of structures, such as neurotransmitter production and activity, metabolism, immune
function, and other interactions. Histochemistry can also be used to reveal chemoarchitecture or chemical neuroanatomy.
Immunocytochemistry is a type of histochemistry that makes use of antibodies to visualize cell types, axons, neuron structures, glial processes, blood
vessels, or molecular components of cells like neurotransmitters and intranuclear proteins. Immunocytochemical studies can also be used for genomics
studies of nervous system cells. Combining these techniques with a fluorescent stain allows visualization of enzyme binding sites and reactions.
In situ hybridization is also an important histochemical tool for neuroanatomy studies. It uses synthetic ribonucleic acid (RNA) probes to visualize
complementary messenger RNA (mRNA) transcripts of genes in the cell. This can help to reveal gene function.

What I Learned In Anatomy Class
My hand was sprinting across the page with charcoal in palm, and the finish line of my sketch was in sight. The image of a model's face was quickly
appearing, and the proportions of her eyes–to–nose and ear–to–mouth were just right. Proportions of the human face were something I learned in art
class, whereas the details in her eyes were something I learned in anatomy class.
I never knew how much I loved science until my love for art developed. As a child, I grew up in a home where my parents encouraged me to flourish
creatively. While we lived in Europe, I thrived on new adventures as they took me to museums, cathedrals, and castles throughout several countries. The
sculptures and paintings of people always amazed me. My small brain could...show more content...
During my time there, I shadowed a pediatric doctor. While I was asking him questions, he was called into an emergency surgery, and I was
unfortunately not old enough to watch according to the hospital restrictions. So as I was waiting around, a PA swooped me up and let me shadow
her instead. I was embarrassed to admit to her that I was not aware of a PA's responsibilities to the hospital. Throughout the rest of the day, I followed
the PA into patient rooms and recovery rooms. I was able to observe how the PA interacted with patients with such a reassuring and caring attitude that
I had not seen with the previous physician I had met. I not only respected her compassionate personality, but I related to it.
My senior year, I desired to see more of what life was like as a PA. Thankfully, I was finally within the age requirement to stand in on surgeries. That
day I saw the PA make the first cut and suture the last stitch. Both were made with such precision and perfection. It hit me; the PA was an artist just like
Rubens, Giorgione, and Michelangelo. The sutures were just as beautiful as the paintings in all the museums to

Anatomy Reflection
What went wrong
As with other PA faculties, you may be aware of the general complaints made by the first year PA students about the Anatomy course. I do know my
classmates were affected different; however, these were my own personal challenges with the Anatomy course:
Disorganization of course material o Class reading assignments did not match Lecture o Lecture PowerPoints were not provided despite request from
several students. It was usually provided a couple of days before the test. This shortened the time to study, memorize and focus on the necessary
anatomical structures.
Lack of guidance on how to study the information presented
–As recommended during the PA orientation, I read the assigned readings for my courses; however, foranatomy, this exercise quickly became futile
only because it did not contribute to helping to understand lectures provided in class. With voluminous reading assignments, many times, the anatomy
lecture focused little or none from the information in the textbook. Lectures mostly presented anatomical structures and so focus on images were
paramount. Therefore, the reading did little to help understand lecture material if one is not familiar enough with the anatomical structures. While this
was the case, the PowerPoints with the anatomical structures were not provided.
Insufficient & consistent guidance in the Anatomy Cadaver lab
–Initially there was no tutoring and/or review sessions for the lab. Many of us were confused and

The lights in the ER blink as the storm rages on outside. I snap back from the sadness of the weather to the job at hand. I rush to the ER to see my
patient has broken bones, a punctured lung, and a laceration along his calf. There's so much blood everywhere, coming from every open wound on his
body. His muscles torn apart and his heart pounding trying to stay alive. Now was my chance everything I learned about anatomy could help me in this
moment. No more time to be wasted I go into the room with anatomy deep in my veins. The knowledge of anatomy helps in the saving of lives, but we
didn't always have this information. Anatomy has a history, however, how did it all begin, and who brought the knowledge ofhuman anatomy to us. To
understand where it all began we have to journey back to 300 BC in the ancient city of Alexandria where we meet Herophilus. For him, it wasn't easy
to study human anatomy because there was a ban on dissections in Alexandria. However once that ban was lifted Herophilus was the first person in
Greece to publicly dissect both human cadavers and animals. Herophilus was then deemed the father of anatomy and with more studying on the brain
he learned that it was the center of the nervous system. Before his time though there was the father of medicine or Hippocrates. Hippocrates was one of
the greatest physicians of his time, and also brought the world of anatomy the Hippocratic oath. Now back to today we've advanced further in the
knowledge of anatomy and

Anatomy and Physiology
The term homeostasis is used to mean maintenance of static or constant conditions in the internal environment in the organism. Essentially all of the
organs and tissues of the body perform functions that help to maintain these constant conditions. For instance, the lungs provide oxygen to the extra
cellular fluid to replenish oxygen that is being used by the cells; the kidneys maintain constant ion concentrations and the gastrointestinal system
provides nutrients.
Not all substances absorbed from the gastrointestinal tract can be used in their absorbed form by the cells. The liver changes the chemical

A large segment of the nervous system is called the autonomic system. It operates at a subconscious level and controls many functions of the internal
organs, including level of pumping activity by the heart, movements of the gastrointestinal tract, and glandular secretion. Neurons are cells that act like
tiny batteries which power electrical circuits within the body. They can transmit impulses from cell to cell for communication, control, and
interpretation of sensory input.
In a typical neuron dendrites respond to stimuli through input to the neuron cell body. When the stimulus is large enough the cell body sends a one
way electrochemical impulse through the axon to the next neuron or to some effector such as a muscle. The most important part of a neuron is its cell
membrane. Using active transport and special Na+/K+ ion pumps in the membrane of the axon a neuron creates a resting potential of –70 millivolts.
The cell essentially becomes a tiny battery ready for action. The action is the action potential –– a wave of electro–chemical activity which sweeps
down the axon in one direction, changing its polarity. Depolarization leads to further depolarization as special electrically sensitive protein gates
swing open allowing Na+ ions to enter the cell and K+ ions to escape.
Once depolarized the Na+/K+ pumps quickly re–polarize the axon by

Review Of ' Grey 's Anatomy '
Grey's anatomy is a television show about a group of surgeons and interns who work at Seattle Grace Hospital. The series emphasizes on a group of
doctors who fight to save their patient 's lives while contending to become the head surgeon. Aside from the competition, they go through a lot of
heartbreak; either relationships problems or family crises throughout each of their lives. The series began with Dr. Meredith Grey (Ellen Pompeo)
starting her career as a medical intern with other interns, who became her friends and roommates later on. Being on air every Wednesday for eleven
years, the show has drawn a beautiful fantasy world, among hospital life; many people, including me being inspired enough to want to join the field.

Neither of them knew their identities until she found him in the hospital elevator wearing his dark blue surgeon 's uniform, perhaps he was also
assigned as a boss of the group she was in. At first, it was nothing more, nothing less than just a one night stand until they found each other in the
same compound again; the Dr. Christina house party. However, watching his marvelous surgery technique the whole day and seeing his humble
personality, Meredith became madly in love with him or as she stated started to love him in a very scary way, then they continued sleeping
together until they get caught by someone; his wife. Even though Dr. Sheppard seems interested in Meredith, he was also "happily" married to Dr.
Addison who lives in New York at that time. So that one night, Meredith had to fly to Chicago for a meeting and Derek was escorting her to the
airport. Unfortunately, that night, his wife was also dreaming about how happy Derek would be when he see her in their bedroom while flying all
the way from New York to Seattle to surprise him. However, opposing to her dream, she found her husband giving a goodbye kiss to another
woman at the airport gate. Dr. Addison could not believe what she was watching until Derek run to her and hug her while Meredith was left with a
confused face. At first, Derek apologized and chose his wife over Meredith. However, as days goes by, he could not resist Meredith's "choose

The cause of the light–headedness is the decreased cardiac output. Her cardio output is 3.2L/min. SV = 40mls .The cause of the mild pulmonary
congestion is increased pulmonary capillary pressure. Atrial fibrillation and decreased C/O and BP would cause dizziness. If the leak is large, it
results in an increase in the pressure in the atrium. Her left atrial pressure is 16 mm Hg .Hypertrophy of the wall of the atrium can occur and the
atrium might dilate. A backpressure of blood may then cause congestion of blood in the pulmonary veins, which bring blood to the left atrium from the
lungs.

Good Morning Mr. Brown, my name is Mona and I am a physician's assistant. Thank you for coming in to meet with me today. Today I'll be going
over your recent lab work along with the results. The last time you were in to see the doctor he ordered testing for you that is known as a lipid panel or a
cholesterol panel. A lipid panel is done to measure four main things which are your cholesterol, triglycerides, HDL, and LDL
I will now tell you a little about your results and explain what your results mean for your health. You may feel free to ask any questions to gain
clarification of anything that you may not understand. First I will discuss your Triglyceride level results, I want to explain to you exactly what
triglycerides are before giving you your personal result. Triglycerides are a type of fat (lipid) found in your blood. Whenever you eat something your
body automatically turns any calories it feels is unnecessary for you to have into triglycerides.
The triglycerides are then stored in your fat cells, and later on the hormones in your body will set free triglycerides to be used as energy for you in
between your meals. Your triglyceride level result is 145 mg/dl which is good. A normal triglyceride level is considered to be Less than 150
milligrams per deciliter (mg/dL). Both Triglycerides and cholesterol are separate types

environmental changes. A really good example of homeostasis is the body keeping the average temperature of 98.6 degrees. Homeostasis is important

There are positive feedback mechanisms and negative feedback mechanisms. Positive feedback is a closed system that occurs in a feedback loop
and the response of the system relies on the feedback system to function. A good example of this would be a blood clot. When a vessel is harmed,
platelets begin to stick to the harmed site and discharge chemicals that pull in more platelets. The platelets keep on heaping up and discharge
chemicals until a coagulation is formed and you now have a blood clot. Negative feedback is a response that causes a decline in its function. It is a
reaction to some kind of stimulus. It usually causes the output of a system to lessen which in turn tends to stabilize the system. The skin protects
underlying tissues and organs, excretes salts, water, and organic wastes. It also regulates your body temperature. The hair protects your scalp from
