What is Endocrine System?
The endocrine system is comprised of nine primary glands that produce hormones and many other organs that provide secondary functions such as processing the secretions to trigger bodily functions.
Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct. The endocrine glands belong to the body’s control system. The hormones which they produce help to regulate the functions of cells and tissues throughout the body.
Major Endocrine Glands
- Pituitary gland (Hypophysis)
- Thyroid gland
- Parathyroid glands
- Adrenal glands
- Pineal gland
These glands produce different types of hormones that evoke a specific response in other cells, tissues, and/or organs located throughout the body.
Pituitary gland (Hypophysis)
The pituitary gland hangs from the base of the brain by a stalk and is enclosed by bone. It consists of a hormone-producing glandular portion and a neural portion.
The thyroid gland is located in the anterior throat. Thyroid follicles store colloid containing thyroglobulin, a glycoprotein from which thyroid hormone is derived.
The parathyroid glands, located on the back aspect of the thyroid gland, which causes an increase in blood calcium levels by targeting bone, the intestine, and the kidneys.
The adrenal glands are located above the kidneys in humans and in front of the kidneys in other animals.
The pancreas, located in the abdomen close to the stomach, is both an exocrine and an endocrine gland.
The ovaries of the female, located in the pelvic cavity, release two main hormones. While, the testes of the male begin to produce testosterone at puberty in response to LH.
The pineal gland is located in the diencephalon. Its primary hormone is melatonin, which influences daily rhythms and may have an antigonadotropi c effect in humans.
