insulin and glucagons in regulating blood sugar. The human body requires that the blood glucose level is maintained in a very narrow range. Homeostasis is regulated by two hormones‚ insulin and glucagon which are both secreted by the endocrine pancreas. The production of insulin and glucagon by these pancreatic cells ultimately determines if a patient has diabetes or another related problem. Insulin is secreted by the beta cells of the pancreas in response to high blood

Endochondral ossification is the process through which the axial and appendicular skeletons are formed through the formation of a cartilage inter-mediate. A good model for endochondral ossification is the limb bud where the precursor cells

which act as “chemical messengers” in an effort to regulate particular bodily functions such as metabolism and growth. These hormones are produced by the pancreas‚ thyroid‚ pituitary‚ pineal‚ and adrenal glands which are also referred to as the endocrine system. Hormones are additionally produced in the ovaries in women and the testes in men. The secretions of particular hormones assist the body in maintaining a state of balance or homeostasis. When one or more hormones within the body are produced

Hypothyroidism Normally‚ the thyroid-stimulating hormone (TSH) is produced when the hypothalamus excretes thyrotropin-releasing hormone (TRH). The secretion of TRH triggers the pituitary gland to release TSH. TSH then activates a release of triiodothyronine (T3) and thyroxine (T4)‚ controlling the body’s metabolism. When T3 and T4 levels rise‚ the secretion of TRH and TSH decrease. When thyroid hormone levels decline‚ there is an increase in TRH and TSH secretion (Buttaro‚ Trybulski‚ Bailey‚ & Sandberg-Cook

Above the kidneys are two yellowish- orange colored glands that are approximately two and half by one inch called the adrenal glands. The adrenal glands play a very important role in secreting hormones and protecting the body from stress. The adrenal glands are composed of two parts‚ the adrenal cortex and the adrenal medulla. The adrenal cortex is the outer part of the adrenal gland that produces steroid hormones that regulate many different body functions. Not only that‚ but a hormone called aldosterone

Adrenal gland In mammals‚ the adrenal glands (also known as suprarenal glands) are the triangular-shaped endocrine glands that sit on top of the kidneys. They are chiefly responsible for releasing hormones in conjunction with stress through the synthesis of corticosteroids and catecholamines‚ including cortisol and adrenaline (epinephrine)‚ respectively. Anatomy and function Anatomically‚ the adrenal glands are located in the retroperitoneum situated atop the kidneys‚ one on each side. They are
