Pituitary gland

1. The thyroid gland secretes thyroxine also known as T4 which maintains metabolic rate of all cells and processes of cell growth and tissue differentiation. 2. Calitonin is secreted by the thyroid gland and maintains calcium and phosphorus blood levels by inhibiting the transfer of calcium from bone to blood, increases calcium storage in bone, and increases renal exertion of calcium and phosphorus. 3. The parathyroid gland secretes parathyroid hormone or parahormone which regulates calcium…

Breastfeeding; the best way to feed a baby. It offers all the valuable nutrients that helps with growing, it offers protection from certain infections and some common childhood illnesses and it increases emotional bonding between mother and child. As valuable as breastfeeding can be, it does present some nuisances; such as learning how to deal with the awkward leaks, spraying, and dribbling that not only occur during active breastfeeding, but can continue long after giving birth and/or…

eyes, ears and mouth are formed. The digestive and urinary systems start functioning as well. The first sign that the mother may experience is a missed period. The embryo’s limbs grow to form webbed feet and hands and the thyroid, adrenal glands and pituitary glands have fully formed and their eyes are now open. At week 8 a diagnostic ultrasound scan can be offered to the mother. At 12 weeks the embryo is now known as a foetus and all the organs and muscles are fully formed. The sex of the…

For many women in today’s society, having a child when the timing is not right is not exactly ideal. For those particular women, there are many options to prevent and terminate pregnancy. Modern contraceptive methods have been available for decades now, thanks to Margret Singer and Katherine McCormick, the inventors of the oral contraceptive pill. Not only that, but due to the breakthrough of the birth control pill, methods have been opened to implantable devices, barrier and hormonal methods,…

happens when the ovaries no longer release an egg every month and menstruation stops. As a woman ages, her ovaries don't respond to FSH or LH as strongly as they used to. FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland, and regulates…

The thyroid gland is an organ in the endocrine system located in the throat next to the Adam’s apple and although small shaped is extremely important to a patient’s health. The primary function of the thyroid is to produce two specific thyroid hormones, triiodothyronine (T3) and thyroxine (T4), and secrete calcitonin that circulates continuously from the gland through the blood to all parts of the body. In fact, thyroid hormones are essential for operating “almost all the cells in the body,…

classical congenital adrenal hyperplasia, it is non-life threatening. The Mayo Clinic, a service that gives people medical information and helps set up doctor appointments, defines NCAH as “a collection of genetic conditions that limit your adrenal glands' ability to make certain vital hormones.” These vital hormones include, but aren’t limited to, estrogen, testosterone, aldosterone, androgens and corticosteroids. Non-classical congenital adrenal hyperplasia is an uncommon disorder affecting…

Joanne’s body responds to hypovolemic shock by triggering the cardiovascular, renal, hematologic and neuroendocrine system for support. The Hematologic system responds to major blood loss by activating coagulation cascades and constricting the vessels that are currently bleeding by release of thromboxane A2 and platelets. What this does is form a colt on the bleeding site. Collagen is exposed by damaged vessels which cause fibrin production and stabilize the clots that have been formed. Usually…

vessels dilating to radiate heat, and sweat glands increasing to increase sweat production. b) Two mechanisms the body uses to heat itself are the blood vessels constrict, reducing heat, and muscles beginning to shiver, generating heat. 11. a) The signal in the feedback loop would be the hypothalamus sensing that the body temperature is too high sending signals to cool the body. The response is the blood vessels dilating (chemical signal), and sweat glands increasing sweat production to…

of which are studied by liberal arts disciplines. To better understand the human response to fear, it helps to understand the body’s response. When a stimulus that triggers fear is encountered, impulses are sent from sympathetic nervous system to glands and smooth muscle. These impulses alert the adrenal medulla to release epinephrine (adrenaline) and norepinephrine (noradrenaline) into the blood stream. These hormones, often referred to as “stress hormones” cause an increase in heart rate and…
