The three main approaches to studying anatomy are regional anatomy, systemic anatomy, and clinical anatomy. Regional anatomy focuses on specific parts of the body, systemic anatomy studies the organ systems, and clinical anatomy emphasizes applying anatomical knowledge to medicine. The document then discusses various anatomical terms including anatomical position, planes, and terms related to location, movement, and laterality.

The concept of planes and axes of movement is a complicated subject for both "nerds" and "novices" to fitness and exercise. This comprehensive infographic (brought to you by the folks at TodaysFitnessTrainer.com) attempts to take the mystery out of the topic and helps to simplify how the body moves in three-dimensional space.
The term anatomy refers to the science that deals with the form and structure of animals. Physiology deals with the study of functions of the body or any of its parts. A thorough knowledge of the structure of an animal imparts a lot of information about the various functions it is capable of performing.
The course may be used as an introductory course to further studies; to assist you in recognising the normal, in order to determine the abnormal; to help you understand how to diagnose disease or determine if an animal has sustained an injury; to help understand the physical capabilities or limitations of particular species; to understand what happens in the nutrition and growth processes; and to assist you to get better performance from your animals.
Anatomy refers to the internal and external structures of the body and their physical relationships, whereas physiology refers to the study of the functions of those structures.

Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

4. APPROACHES TO STUDYING ANATOMY
The three main approaches to studying
anatomy are
1. Regional Anatomy
2. Systemic Anatomy, and
3. Clinical Anatomy (or applied)
reflecting the body's organization and the
priorities and purposes for studying it.
5. The three main
approaches to studying
anatomy are
Systemic
Regional Clinical
6. 1. Regional Anatomy (topographical
anatomy) considers the organization of the
human body as major parts or segments :
Body
consisting of
the head
neck
trunk (subdivided into
thorax, abdomen, back, and pelvis/perineum)
limbs paired upper and lower
limbs.
7.
8. All the major parts may be
further subdivided into areas
and regions
9. Regional anatomy is the method of studying
the body's structure by focusing attention on a
specific part (e.g., the head),
area (the face), or
region (the orbital or eye region);
examining the arrangement and relationships of
the various systemic structures
(muscles, nerves, arteries, etc.) within it;
10. Surface Anatomy
Surface anatomy is an essential part of the
study of regional anatomy
provides information about structures that may
be observed or palpated beneath the skin.
In short, surface anatomy requires a thorough
understanding of the anatomy of the
structures beneath the surface
12. 2. Systemic Anatomy
is the study of the body's organ
systems that work together to carry out
complex functions.
The basic systems and the field of study or
treatment of each (in parentheses) are:

20. Anatomical Position
The anatomical position refers to the body
position as if the person were standing upright
with the:
head, gaze (eyes), and toes directed
anteriorly (forward),
arms adjacent to the sides with the palms
facing anteriorly, and
lower limbs close together with the feet
parallel.
21.
22.
23. Anatomical Planes
Anatomical descriptions are based on four imaginary
planes (median, sagittal, frontal, and transverse)
that intersect the body in the anatomical position
The median plane, the vertical plane
passing longitudinally through the body, divides
the body into right and left halves.
The plane defines the midline of the
head, neck, and trunk where it intersects the
surface of the body. Midline is often
erroneously used as a synonym for the
24. Sagittal planes are vertical planes
passing through the body parallel to
the median plane.
Parasagittal is commonly used but is
unnecessary because any plane parallel to and
on either side of the median plane is sagittal
by definition.
However, a plane parallel and near to the
median plane may be referred to as a
paramedian plane.
25. Frontal (coronal) planes
are vertical planes passing through
the body at right angles to the median
plane, dividing the body into anterior (front) and
posterior parts or back
Transverse planes are horizontal planes
passing through the body at right angles to the
median and frontal planes, dividing the body
into superior (upper) and inferior (lower)
parts.
Radiologists refer to transverse planes as
transaxial, which is commonly shortened to axial
planes
26.
27. Oblique sections
are slices of the body or any of
its parts that are not cut along the previously
listed anatomical planes. In practice, many
radiographic images and anatomical sections
do not lie precisely in sagittal, frontal, or
transverse planes; often they are slightly
oblique.
28. Terms of Relationship and Comparison
Superior / above
a structure that is nearer the vertex, the top
most point of the cranium
Cranial relates to the cranium and is a useful
directional term, meaning toward the head or
cranium.
Inferior / below
. a structure that is situated nearer the sole of
the foot
29. Caudal (L. cauda, tail) is a useful directional
term that means toward the feet or tail
region, represented in humans by the coccyx
(tail bone)
Posterior / behind
Posterior (dorsal) denotes the back surface of
the body or nearer to the back.
Anterior / infront
Anterior (ventral) denotes the front surface of
the body. Rostral is often used instead of
anterior
30. Medial
a structure is nearer to the median plane of the
body.
For example, the 5th digit of the hand
(little finger) is medial to the other digits.
Lateral
lateral stipulates that a structure is farther away
from the median plane.
The 1st digit of the hand
(thumb) is lateral to the other digits s of
Movement
31. Terms of Laterality
Paired structures having right and left members
(e.g., the kidneys) are bilateral,
whereas those occurring on one side only
(e.g., the spleen) are unilateral.
Something occurring on the same side of the
body as another structure is ipsilateral
Something occurring on the opposite side of the
body relative to another structure is
contralateral;
32. Terms of Movement
Flexion indicates bending or decreasing
the angle between the bones or parts
of the body. For most joints
(e.g., elbow), flexion involves movement in an
anterior direction.
Extension indicates straightening or
increasing the angle between the
bones or parts of the body. Extension usually
occurs in a posterior direction.
33.
34. The knee joint, rotated 180° to other joints, is
exceptional in that flexion of the knee involves
posterior movement and extension involves
anterior movement.
Dorsiflexion describes flexion at the
ankle joint, as occurs when walking uphill or
lifting the front of the foot and toes off the
ground
Plantarflexion bends the foot and
toes toward the ground, as when standing on
your toes.
35.
36.
37. Extension of a limb or part beyond the normal
limit—hyperextension (overextension)—can
cause injury, such as “whiplash”
(i.e., hyperextension of the neck during a rear-
end automobile collision).
Except for the digits,
Abduction means moving away from the
median plane (e.g., when moving an upper
limb laterally away from the side of the body)
Adduction
means moving toward it
38.
39. Circumduction is a circular movement that
involves sequential
flexion, abduction, extension, and adduction (or in
the opposite order) in such a way that the distal end
of the part moves in a circle
Rotation
involves turning or revolving a part of
the body around its longitudinal axis, such as
turning one's head to face sideways.
Medial rotation (internal rotation) brings the anterior
surface of a limb closer to the median plane,
lateral rotation (external rotation) takes the anterior
surface away from the median plane.
40. Pronation rotates the radius medially so that
the palm of the hand faces posteriorly and its
dorsum faces anteriorly.
When the elbow joint is
flexed, pronation moves the hand so that the
palm faces inferiorly movement, rotating the
radius laterally and uncrossing it from the
ulna, returning the pronated forearm to the
anatomical position.
When the elbow joint is flexed, supination
moves the hand so that the palm faces
superiorly.
41.
42. (Memory device: You can hold soup in the palm
of your hand when the flexed forearm is
supinated but are prone [likely] to spill it if the
forearm is then pronated!).
43. Eversion moves the sole of the foot away from
the median plane, turning the sole laterally
When the foot is fully everted it
is also dorsiflexed.
Inversion moves the sole of the foot toward the
median plane (facing the sole medially).
When the foot is fully inverted it
is also plantarflexed.
44. Pronation of the foot actually refers to a
combination of eversion and abduction that
results in lowering of the medial margin of the
foot (the feet of an individual with flat feet are
pronated)
supination of the foot generally implies
movements resulting in raising the medial
margin of the foot, a combination of inversion
and adduction.
