The existence of both nervous factor and humoral factor in stimulating the gastric secretion can be demonstrated by the Vagal stimulation of the exocrine pancreas.
The pituitary gland is responsible for stimulating growth and secretion of hormones from other glands in the body. It releases various hormones that regulate functions such as growth, reproduction, and metabolism.
Parasympathetic stimulation of the intestine increases motility by promoting smooth muscle contractions and enhances digestive gland secretion by stimulating the release of digestive enzymes and fluids.
High levels of thyroxine in the blood negatively feedback to the pituitary gland, reducing the secretion of thyroid-stimulating hormone (TSH). Conversely, low levels of thyroxine signal the pituitary gland to increase TSH secretion to stimulate the thyroid gland to produce more thyroxine.
When blood calcium levels increase, the secretion of parathyroid hormone (PTH) decreases. PTH helps regulate calcium levels by stimulating the release of calcium from bones and increasing its reabsorption in the kidneys. When blood calcium levels are already high, PTH secretion is reduced to prevent further elevation.
Inhibin is a hormone that specifically suppresses spermatogenesis without affecting testosterone secretion. It is produced by the Sertoli cells in the testes and acts to inhibit the secretion of follicle-stimulating hormone (FSH) from the pituitary gland, which is necessary for sperm production. This helps to regulate the balance of hormones involved in male reproductive function.
Melanophore stimulating hormone (MSH) secretion from the vertebrate is regulated by the hypothalamus. Removal of the pituitary from control results in an autonomous uninhibited secretion of MSH.
Follicle-stimulating hormone (FSH) secretion is primarily regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus. GnRH stimulates the release of FSH from the anterior pituitary gland. Additionally, negative feedback from sex steroids such as estrogen and testosterone can also influence FSH secretion.
luteinizing hormone (LH)
The pituitary gland is responsible for stimulating growth and secretion of hormones from other glands in the body. It releases various hormones that regulate functions such as growth, reproduction, and metabolism.

Thyroid stimulating hormone (TSH) stimulates the secretion of the hormones thyroxine (T4) and triiodothyronine (T3).
Growth hormone, thyroid stimulating hormone, follicle-stimulating hormone, luteinizing hormone, prolactin, adrenocorticotropic hormone all require releasing hormones from the hypothalamus.
