Pituatary gland (hypophysis)
|
Located at the base of the brain, small pea-shaped gland attached to the hypothalamus. Referred to as the master gland of the endocrine system. Produces Adrenocorticotropic, gonadotropic, growth, thyroid-stimulating, Prolactin, Antidiuretic, and Oxytocin hormones.
|
Thyroid gland
|
H-shaped organ comprising two lobes that lie on either side of the trachea, connected by a strip of tissue called isthmus. Largest gland of the endocrine system, positioned just below the larynx. Produces three hormones. Produces triiodothyronine, thyroxing, and calcitonin hormones.
|
Parathyroid glands
|
Four glands: a superior pair and an inferior pair, which are attached to each lateral thyroid lobe. Produces parathormone hormone.
|
Adrenal glands (suprarenal)
|
Attached to the upper portion of each kidney. Suprarenal refers to the location (above=supra). Each is structurally and functionally differentiated into an outer region, the adrenal cortex, and an inner region, the adrenal medulla. Produces sex, mineralocorticoids, and glucocorticoids hormones.
|
Pancreas (islets of Langerhans)
|
Located posterior to the stomach, between the spleen and duodenum. Functions as endo and exocrine gland. Produce two hormones: glucagon and insulin.
|
Ovaries
|
Almond shaped glands located in the pelvic cavity of a female, one on each side of the uterus. Produce the ovum.
|
Testes
|
Two oval glands in a male that lie in the scrotum. Produce spermatozoa.
|
Thymus gland
|
Positioned in front of the aorta and behing the sternum. It comprises lymphatic tissue and serves as the site of production of a hormone called thymosin.
