The document discusses the three main types of muscle tissue - skeletal, smooth, and cardiac muscle. It also outlines the parts of a muscle and different pairs of muscles that work antagonistically to move bones in opposing directions, including flexor/extensor, adductor/abductor, levator/depressor, rotator, and sphincter/dilator muscles. The muscular system holds the skeleton together, protects organs, and supports body movement using arranged muscles that work in opposing pairs to pull bones in different directions.

Locomotion is movement of an organism from one place to another while movements can be performed at any particular space also. Bending of limbs, peristaltic movements, blinking of eye lids etc are some examples of movements. Locomotion is related with movements. Together, our bones, muscles, and joints - along with tendons, ligaments, and cartilage - form our musculoskeletal system and enable us to do everyday physical activities. In this lesson you will learn about : 1) Functions of Human Skeleton 2) Parts of Skeletal System 3) Bone - Composition, Structure, Classification 4) The Human Skeleton 5) Joints 6) Lever Mechanism I hope this document is helpful to you. Please share the document with your friends if you think this will benefit them. Get ready for the next lesson. Thanks.

The skeletal system includes all of the bones and joints in the body. Each bone is a complex living organ that is made up of many cells, protein fibers, and minerals. The skeleton acts as a scaffold by providing support and protection for the soft tissues that make up the rest of the body. The skeletal system also provides attachment points for muscles to allow movements at the joints. New blood cells are produced by the red bone marrow inside of our bones.

Physiology of Special Chemical Sensation of Taste

MedicoseAcademics

Title: Sense of Taste Presenter: Dr. Faiza, Assistant Professor of Physiology Qualifications: MBBS (Best Graduate, AIMC Lahore) FCPS Physiology ICMT, CHPE, DHPE (STMU) MPH (GC University, Faisalabad) MBA (Virtual University of Pakistan) Learning Objectives: Describe the structure and function of taste buds. Describe the relationship between the taste threshold and taste index of common substances. Explain the chemical basis and signal transduction of taste perception for each type of primary taste sensation. Recognize different abnormalities of taste perception and their causes. Key Topics: Significance of Taste Sensation: Differentiation between pleasant and harmful food Influence on behavior Selection of food based on metabolic needs Receptors of Taste: Taste buds on the tongue Influence of sense of smell, texture of food, and pain stimulation (e.g., by pepper) Primary and Secondary Taste Sensations: Primary taste sensations: Sweet, Sour, Salty, Bitter, Umami Chemical basis and signal transduction mechanisms for each taste Taste Threshold and Index: Taste threshold values for Sweet (sucrose), Salty (NaCl), Sour (HCl), and Bitter (Quinine) Taste index relationship: Inversely proportional to taste threshold Taste Blindness: Inability to taste certain substances, particularly thiourea compounds Example: Phenylthiocarbamide Structure and Function of Taste Buds: Composition: Epithelial cells, Sustentacular/Supporting cells, Taste cells, Basal cells Features: Taste pores, Taste hairs/microvilli, and Taste nerve fibers Location of Taste Buds: Found in papillae of the tongue (Fungiform, Circumvallate, Foliate) Also present on the palate, tonsillar pillars, epiglottis, and proximal esophagus Mechanism of Taste Stimulation: Interaction of taste substances with receptors on microvilli Signal transduction pathways for Umami, Sweet, Bitter, Sour, and Salty tastes Taste Sensitivity and Adaptation: Decrease in sensitivity with age Rapid adaptation of taste sensation Role of Saliva in Taste: Dissolution of tastants to reach receptors Washing away the stimulus Taste Preferences and Aversions: Mechanisms behind taste preference and aversion Influence of receptors and neural pathways Impact of Sensory Nerve Damage: Degeneration of taste buds if the sensory nerve fiber is cut Abnormalities of Taste Detection: Conditions: Ageusia, Hypogeusia, Dysgeusia (parageusia) Causes: Nerve damage, neurological disorders, infections, poor oral hygiene, adverse drug effects, deficiencies, aging, tobacco use, altered neurotransmitter levels Neurotransmitters and Taste Threshold: Effects of serotonin (5-HT) and norepinephrine (NE) on taste sensitivity Supertasters: 25% of the population with heightened sensitivity to taste, especially bitterness Increased number of fungiform papillae

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.

i3 Health

i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource. This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and Associate Division Director for Ambulatory Operations The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma. STATEMENT OF NEED Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL. Target Audience Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL). Learning Objectives 1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL 2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults 3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

The prostate is an exocrine gland of the male mammalian reproductive system It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ). It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes It’s work is regulated by androgens which are responsible for male sex characteristics Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

Flu Vaccine Alert in Bangalore Karnataka

addon 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!
