thyroid gland is an integral part of the endocrine system in the human body. The thyroid gland secretes the thyroid hormone‚ which plays an important role in the growth of the body. The thyroid is butterfly shaped‚ and located at the bottom of the neck. Two important hormones produced by the thyroid gland are thyroxine and triidothyronine. Both of these hormones help the body grow after birth‚ and they also aid tissues increase their oxygen use within these tissues. The thyroid gland secretes

Are Apocrine Glands? Apocrine glands are located in the skin‚ breasts‚ eyelids‚ and ears. They are a type of exocrine gland‚ which are glands that secrete hormones into a duct. Counterparts of exocrine glands are endocrine glands that secrete their hormones directly into the bloodstream. Certain endocrine glands also release hormones called pancrines that affect only specifically targeted cells very close to where they are released. Examples of endocrine glands are the pituitary gland‚ pancreas‚

Pituitary Gland (Hypophysis) About the size and shape of a pea‚ located in the sella turcica of the sphenoid bone‚ attached to the hypothalamus via a stalk called the infundibulum. It has two major lobes‚ one neural and one glandular. Posterior Lobe (Neurohypophysis) – composed of nervous tissue; releases neurohormones that it receives ready-made from the hypothalamus; oxytocin and anti-diuretic hormone (ADH); released on demand in response to nerve impulses from hypothalamic neurons.

The thyroid gland is an important organ of the endocrine system and located in front of the neck below the larynx consisting of two lobes on each side of the windpipe. It regulates the physical and chemical processes that occur at the cellular level. It regulates the manner and rate at which the tissues utilize food and natural chemicals for the production of energy and to expend that energy into body heat and muscular energy. The thyroid gland produces hormones from the thyroid tissue cells called

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
