Endocrine System Six Glands
Adrenal Glands
Ductless, pyramid-shaped glands that are situated on the top of each kidney. There are two structural parts of the adrenal gland. The inner portion is called the medulla and the outer portion is the cortex. The medulla secretes epinephrine and norepinephrine. The cortex secretes several steroids such as glucocorticoids, mineral corticoids, and adrenal estrogens and androgens.

Adrenal Glands
Carotid Body
Located on each side at the bifurcation (division) of the common carotid arteries. Although not a true endocrine structure, it is made of both glandular and nonglandular cells. The carotid body detects changes in pH, temperature, and partial pressure of oxygen and carbon dioxide

Carotid Body
Parathyroid Gland
Small round bodies that are located on the posterior side of the thyroid gland and embedded in the connective tissue surrounding it. These glands regulate calcium and phosphorus metabolism

Parathyroid Gland
Pituitary Gland (hypophysis cerebri)
This single gland has two separate parts located in an area of the brain just under the hypothalamus. The posterior pituitary or neurohypophysis secretes oxytocin, a hormone responsible for uterine contractions and the “let down” reflex of milk in response to a baby’s suckling; and vasopressin, an antidiuretic. The anterior pituitary manufactures the adrenocorticotrophic hormone (ACTH), thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH), luteinizing hormone (LH), growth hormone (GH), somatotropin, melanocyte stimulating hormone (MSH), and prolactin (PRL).

Pituitary Gland (hypophysis cerebri)
Thymus Gland
Located in the mediastinum of the chest, this gland helps to regulate humoral immune functions and is most active in early childhood. By puberty, it may be replaced by fat

Thymus Gland
Thyroid Gland
Located in the neck just below the thyroid cartilage of the trachea, it regulates metabolism and serum calcium levels through the secretion of thyroid hormone and Calcitonin
