MICROANATOMY

Detailed explanation-1: -Hypothalamus: The hypothalamus (hi-po-THAL-uh-mus) is in the lower central part of the brain. It links the endocrine system and nervous system. Nerve cells in the hypothalamus make chemicals that control the release of hormones secreted from the pituitary gland.

Detailed explanation-2: -The production of hormones in the anterior lobe itself is regulated in two ways: Through the hypothalamus, which makes hormones (known as “releasing hormones”) that increase the production of hormones in the anterior lobe or hormones (known as “inhibiting hormones”) that reduce it.

Detailed explanation-3: -The posterior pituitary does not produce its own hormones; instead, it stores two hormones-vasopressin and oxytocin-that are produced by neurons in the hypothalamus. Both hormones collect at the ends of the neurons, which are located in the hypothalamus and extend to the posterior pituitary.

Detailed explanation-4: -Follicle-Stimulating Hormone and Luteinizing Hormone Puberty is initiated by gonadotropin-releasing hormone (GnRH), a hormone produced and secreted by the hypothalamus. GnRH stimulates the anterior pituitary to secrete gonadotropins-hormones that regulate the function of the gonads.

Detailed explanation-5: -The clusters of cells that produce the six anterior pituitary hormones are under hypothalamic control. Unlike the posterior pituitary which basically stores hormones produced by the hypothalamus, the hypothalamus regulates the anterior pituitary via secreting “releasing hormones, ‘’ somatostatin and dopamine.
