Discribe the pituitary gland and thyroid gland and ovary and testis
Answers
Pituitary gland
The pituitary gland, or hypophysis, is an endocrine gland about the size of a pea. It weighs less than an ounce and is one of the most important organs in the body. It is located at the base of the brain and is closely connected to the hypothalamus. The pituitary gland secretes nine hormones that regulate homeostasis by stimulating other endocrine glands to produce and secrete their own hormones.
Thyroid
The butter-fly shaped thyroid gland is one of the largest endocrine glands. The thyroid gland is in the front of the neck, just below the thyroid cartilage or “Adam’s apple”. The isthmus bridges the two lobes of the thyroid and is located below the cricoid cartilage.
Ovaries
The ovary is an ovum-producing reproductive organ, often found in pairs in the female reproductive system. Ovaries in women are analogous to testes in males—they are both gonads and endocrine glands. Our ovaries produce estrogen, progesterone, relaxin and inhibin.
Testes
The testicle is the male gonad. Like the ovaries in women to which they are homologous, testes are components of both the reproductive system and the endocrine system. The primary functions of the testes are to produce inhibin, sperm (spermatogenesis) and androgens, primarily testosterone.
The pituitary gland is often dubbed the “master gland” because its hormones control other parts of the endocrine system, namely the thyroid gland, adrenal glands, ovaries, and testes. ... In some cases, the hypothalamus signals the pituitary gland to stimulate or inhibit hormone production.
