The thyroid gland is located in the neck and produces three main hormones: T4, T3, and calcitonin. T4 makes up 90% of hormone production while T3 is 9-10%. The gland contains follicles lined with cells that secrete thyroglobulin into the follicular cavity. Iodine is added to thyroglobulin's tyrosine residues to form T4 and T3, which are stored in thyroglobulin vesicles until needed. When secreted into blood, T4 and T3 bind transport proteins while T3 has a faster action time due to weaker binding. The thyroid regulates metabolism through hormone synthesis and secretion.
The pituitary gland is a small gland located at the base of the brain. It has an anterior and posterior lobe. The anterior lobe secretes growth hormone and other hormones that regulate many bodily functions. Growth hormone increases protein synthesis and breaks down fat. It also stimulates bone and cartilage growth. The posterior lobe stores and releases oxytocin and vasopressin (ADH) which are synthesized in the hypothalamus. Oxytocin stimulates uterine contractions and milk ejection while ADH regulates water balance.
The document discusses the hypothalamic factors and anterior pituitary hormones. It begins by describing the structure and functions of the anterior pituitary gland and its connection to the hypothalamus. It then summarizes the six main hormones secreted by the anterior pituitary - growth hormone, adrenocorticotropic hormone, thyroid-stimulating hormone, prolactin, follicle-stimulating hormone, and luteinizing hormone. It explains how these hormones control various target glands and metabolic functions throughout the body. Finally, it discusses how the hypothalamus controls pituitary secretion through releasing and inhibitory hormones, and provides examples of anterior pituitary hyperactivity and hypoactivity disorders.
The parathyroid glands secrete parathyroid hormone (PTH) which regulates blood calcium levels. PTH increases calcium resorption from bones and reabsorption from kidneys to raise calcium levels. It also increases vitamin D activation in kidneys to boost calcium absorption in the gut. PTH secretion is regulated by blood calcium and phosphate levels, increasing when calcium is low or phosphate is high to restore normal calcium concentrations.
The document discusses the endocrine system and pituitary gland. It defines the endocrine system as a group of glands that secrete hormones directly into the bloodstream to regulate organ and cell activity. The pituitary gland, also called the "master gland", is a pea-sized gland located in the brain that controls the function of other glands. The pituitary gland is divided into the anterior and posterior pituitary. The anterior pituitary secretes hormones like growth hormone, TSH, and prolactin, while the posterior pituitary secretes oxytocin and vasopressin (ADH). The document provides details on the functions of these hormones and conditions related to hormone imbalances.
The heart receives its blood supply from two coronary arteries - the right and left coronary arteries. These branch directly off the aorta. The right coronary artery supplies the right atrium and ventricle as well as parts of the left ventricle and septum. The left coronary artery is larger and supplies the left atrium and ventricle as well as parts of the right ventricle. Blood is drained from the heart by the coronary sinus and smaller cardiac veins which drain into the right atrium. Disruptions to this delicate blood supply can cause chest pain or heart attacks.
Thyroid hormones T3 and T4 are produced by the thyroid gland and regulate metabolism. T4 is converted to the more active T3 in tissues. Their production requires iodine and is regulated by TSH from the pituitary which is inhibited by thyroid hormone feedback. Thyroid hormones act through nuclear receptors to increase gene transcription and metabolism. Deficiency causes hypothyroidism while excess causes hyperthyroidism, and both can impact growth, development and multiple body systems.
The thyroid gland produces three main hormones: T4, T3, and calcitonin. T4 is produced in larger amounts than T3. Both are produced through a process involving iodine uptake and binding to tyrosine residues on thyroglobulin within the thyroid follicle. T3 has greater biological activity than T4. Hypothyroidism occurs when not enough hormones are produced, while hyperthyroidism is an overproduction. Diseases are treated through antithyroid drugs, radioactive iodine therapy, or thyroid surgery.

This document provides an overview of testosterone, including its structure, secretion, effects, and mechanisms of action. Testosterone is the principal male sex hormone. It is secreted primarily by the testes in males and the ovaries in females. Testosterone promotes the development of male secondary sex characteristics, increases muscle and bone mass, and supports male sexual functions and spermatogenesis. It works primarily by binding to androgen receptors in cells or being aromatized into estradiol. Abnormalities in testosterone levels or signaling can result in various medical conditions.
The respiratory system has an upper respiratory tract consisting of the nose, nasal cavities, and pharynx, and a lower respiratory tract consisting of the larynx, trachea, bronchi, bronchioles, and lungs. The nose warms, moistens, and filters air and detects odors. The lungs contain bronchioles that divide into microscopic air sacs called alveoli where gas exchange takes place. The lungs are surrounded by pleural membranes that produce a fluid allowing the lungs to move smoothly within the chest cavity during breathing.
The pineal gland is a small organ attached to the brain that secretes melatonin. Melatonin helps coordinate circadian rhythm and inhibits growth of sex organs before puberty. The thymus gland is an organ in the chest that produces thymosin and helps educate T-lymphocytes to fight infections. Both glands play important roles in the immune, endocrine, and developmental systems.
Parturition is the process of delivery of the fetus from the mother's body at the end of pregnancy through labor. Labor contractions arise from the fundus of the uterus and push the fetus against the cervix, resulting in cervical dilation and the opening of the vaginal canal. The stages of parturition include the first stage of cervical dilation and effacement, the second stage of delivery of the fetus, and the third stage of delivery of the placenta. Weak, irregular Braxton Hicks contractions start after 6 weeks of pregnancy to prepare the uterus for labor, while more intense false labor contractions near delivery help further cervical dilation.

Parathyroid hormone (PTH) regulates calcium levels in the blood. It is secreted by the parathyroid glands in response to low blood calcium. PTH acts on the kidneys to reduce calcium excretion, on bones to stimulate calcium release, and on the intestines to increase calcium absorption. PTH levels are regulated through a negative feedback loop, maintaining blood calcium homeostasis. Disorders occur when the parathyroid glands secrete too much or too little PTH, leading to hyper- or hypoparathyroidism and impacting bone and kidney health.

Estrogen and progesterone are the two main ovarian hormones. Estrogen is produced primarily in the ovaries and stimulates the development of female reproductive organs and secondary sex characteristics. It also regulates the female estrus cycle. Progesterone is produced in the ovaries and placenta during pregnancy. It prepares the uterus for pregnancy and maintains pregnancy by supporting embryo development. Both hormones work together to regulate the female reproductive system.
This document discusses the physiological functions of thyroid hormones. It describes how thyroid hormones increase transcription of genes, cellular metabolic activity, and growth. It also covers the metabolic and non-metabolic effects of thyroid hormones on specific body systems and functions like the central nervous system, bone growth, muscle function, cardiovascular system, sleep, and the reproductive system.
The document describes the anatomy and function of the diaphragm. It is divided into three parts: the sternal, costal, and lumbar parts. The sternal part arises from the xiphoid process, the costal part from the lower six ribs, and the lumbar part from the lumbar vertebrae. The diaphragm is innervated by the phrenic nerves and contracts during inspiration to flatten its shape and increase the vertical diameter of the thorax. Relaxation of the diaphragm allows expiration to occur as the thorax decreases in size. The diaphragm plays an important role in respiration and separates the thoracic and abdominal cavities.
Thyroid hormones have two main functions: increasing basal metabolic rate and stimulating growth in children. They act on many body systems including increasing metabolism, protein synthesis, and heart rate. Thyroid hormones are essential for normal growth and development, regulating weight and temperature, and maintaining function of the brain, muscles, reproductive system, and other major organ systems. Abnormal thyroid hormone levels can cause many clinical effects.
The renin-angiotensin-aldosterone system (RAAS) is activated when arterial pressure decreases. Renin is released by the kidneys and converts angiotensinogen to angiotensin I. Angiotensin I is then converted to angiotensin II by angiotensin converting enzyme (ACE), mostly in the lungs. Angiotensin II stimulates aldosterone release from the adrenal cortex and causes vasoconstriction. This increases blood volume and arterial pressure through sodium and water retention and raised peripheral resistance.
The cardiac cycle consists of rhythmic changes that occur with each heartbeat. It has several phases including isovolumic contraction, ejection, isovolumic relaxation, and atrial systole. Heart sounds are produced by the closing of valves and include S1, S2, S3, S4, and murmurs. An electrocardiogram (ECG) records the electrical activity of the heart through electrodes on the skin and analyzes waves, intervals, and other characteristics to evaluate heart rate and identify conditions like coronary artery disease.
This document contains 10 questions about anatomical structures and attachments related to the femur. Each question provides multiple choice answers about landmarks and attachments on different regions of the femur, including the greater trochanter, lesser trochanter, linea aspera, and femoral condyles. The questions are followed by explanations identifying which answers are correct and incorrect for each question.
Functions of skin regulation of body temperaturemurugavel rajen
The skin plays an important role in regulating body temperature. The hypothalamus controls temperature regulation by activating mechanisms for both heat loss and heat gain. When body temperature rises, the hypothalamus stimulates sweating and cutaneous blood vessel dilation to promote heat loss. When body temperature falls, the hypothalamus inhibits heat loss and stimulates shivering and hormonal responses to increase heat production through metabolic activity and thyroid function. Precise regulation of these mechanisms allows humans and other mammals to maintain a constant internal temperature.
The thyroid gland is a butterfly-shaped organ located in the neck below the larynx. It is composed of follicles containing colloid surrounded by follicle cells that produce thyroid hormones like T3 and T4. The hormones regulate metabolism and are synthesized through a process involving iodine uptake, incorporation into the hormones, and diffusion out of the gland. Disorders can arise from abnormal hormone secretion levels like hyperthyroidism and hypothyroidism, or from non-toxic goiter causing gland enlargement without excess hormones.
The heart is a cone-shaped organ located in the chest cavity between the lungs. It is surrounded by fluid-filled sac called the pericardium. The heart has four chambers - two upper atria that receive blood and two lower ventricles that pump blood out. Blood flows through valves from the atria to ventricles and then out arteries or pulmonary artery. The heart's wall has three layers - outer epicardium, middle muscular myocardium, and inner endocardium. The heart continuously contracts and relaxes in a cardiac cycle of diastole and systole to pump blood through the body.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

50. results from compression on the ulnar nerve in the
Cubital tunnel behind the medial epicondyle
causing numbness
and tingling in the ring and little fingers.
The tunnel is formed by the medial epicondyle, ulnar
collateral ligament, and two heads of the flexor carpi
ulnaris muscle
transmits the ulnar nerve and
superior ulnar collateral or posterior ulnar recurrent
artery.
51.
52. is caused by compression of the median nerve due to
the reduced size of the osseofibrous carpal tunnel, resulting
from inflammation of the flexor retinaculum, arthritic
changes in the carpal bones, or inflammation or thickening
of the synovial sheaths of the flexor tendons. It leads to
pain and paresthesia (tingling, burning, and
numbness) in the hand in the area supplied by the
median nerve and may also cause atrophy of the thenar
muscles in cases of severe compression. However, no
paresthesia occurs over the thenar eminence of skin
because this area is supplied by the palmar cutaneous
branch of the median nerve.
53. ■ Is a triangular interval bounded medially by the
tendon of the extensor pollicis longus muscle and
laterally by the tendons of the extensor pollicis brevis
and abductor pollicis longus muscles.
■ Is limited proximally by the styloid process of the
radius.
■ Has a floor formed by the scaphoid and trapezium
bones and crossed by the radial artery.
