adrenal medulla/adrenaline * Paracrine - that secretes hormones that affect adjacent cells e.g. gastric mucosa/gastrin/gastric pits. * Autocrine – regulate their own avtivity by the secretion of hoirmone e.g. interstitial cells of testis/testosterone Each target cell in the body is regulated only by those hormones to which it has receptor molecules , and not y others.different cells may respond in different ways to the same hormone – the transduction machinery of different target cells ‘reads’ the hormone signal in different ways. Blood hormone concentrationare usually governed by negative feedback control – a reduction in concentration stimulates additional secretion and an increase in concentration inhibits further secretion.
a) thyroid hormones b) insulin and glucagon c) parathyroid hormone and calcitonin d) glucocorticoids and mineralocorticoids 5. Which of these organelles is concerned with digestion "within" the cell? a) lysosomes b) Golgi body c) mitochondria d) endoplasmic reticulum 11. After leaving the right ventricle, blood enters the a) aorta b) vena cavae c) pulmonary vein d) pulmonary
What are the thymus gland functions? The thymus functions chiefly to develop T lymphocytes. Once mature, these cells leave the thymus and are transported via blood vessels to the lymph nodes and spleen. T-lymphocytes are responsible for cell mediated immunity, which is an immune response that involves the activation of certain immune cells to fight infection. 4.
(Calcium ions) are stored in the Sarcoplasmic reticulum. 4. The cause for the release of Calcium is the depolarization of the T-tubules. (Acetylcholine enters the synaptic cleft gap and opens the chemically gated sodium channel that starts an action potential spreading down the sarcolemma of the myofibril. This will cause an action potential to spread down to the T- tubules and “electrical chemical signals = shocks” the sarcoplasmic reticulum into releasing calcium ions.
Calcium ions then spread into the synaptic bulb, and Ach is released by vesicles into the synaptic cleft. Na+ ions go into the channels and K+ leaves. Na+ sets up action potential on the sarcolemma, and the muscle fiber is provoked. The action potential travels to the T tubules, and Ca2+ is released into the sarcoplasm. Ca2+ binds to the troponin, which results in a movement in the tropomyosin.
The specific substrate in this case that is acted by Aldolase B is fructose-1-phosphate. This is later converted into DHAP and glyceraldehyde. The product, once finished, will then enter the glycolysis cycle to form ATP (Hudon-Miller, 2012c). Role of Aldolase B in the Breakdown of Fructose Aldolase B is found mostly in the liver but can also be present at lower levels in the kidney and intestinal cells. It is involved in breaking down a simple sugar called fructose.
Homeostatic Imbalance/Unit 8 Assignment William Thornbury Introduction to Anatomy and Physiology SC121 Instructor: Eric D. Steelman, DHSc(c), MPH, MS, RLATG 10/17/14 Homeostatic Imbalance The endocrine system helps regulate and maintain various body functions by synthesizing (making) and releasing hormones, chemical messengers. The major areas of control and integration include responses to stress and injury, growth and development, absorption of nutrients, energy metabolism, water and electrolyte balance, reproduction, birth, and lactation. The endocrine system is composed of glands that release their hormones directly into the bloodstream for chemical signaling of target cells. Typically, the body synthesizes hormones in one part and transports it to another through the bloodstream or lymph. Endocrine glands have a rich blood supply through which hormones travel to reach their target organs.
hCG effects the hormone LH (Luteinizing hormone) and the target tissue is the ovaries in women and testis in men. Symptoms of hCG include morning sickness, Hyperthyroidism, and Ovarian Hyperstimulation Syndrome. Raised hGC levels can cause multiple fetuses, Hydatidiform Mole, and Choriocarcinoma. You can receive hCG injections or orally to correct you hCG level. Cushing’s disease is a condition where the pituitary gland releases too much adrenocorticotropic (ACTH).
For insertion of sperm (in semen) with the female to produce offspring, so continues the cycle of human life. * Prostate- The function of the prostate gland is to secrete proteins and hormones that are added to the ejaculatory fluid produced by the seminal
