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.
Anterior pituitary gland. It secretes Growth hormone,Thyroid stimulating hormone,Adrenocorticotrophic hormone, Follicle stimulating hormone,Leutenizing hormone,Prolactin hormone.
The hormone that regulates the synthesis and secretion of T3 (Triiodothyronine) and T4 (Thyroxine) by the thyroid gland is thyroid stimulating hormone (TSH) that is produced and secreted by the anterior pituitary gland, also known as the adenohypophysis.
Grave's disease is an autoimmune disease which causes hyperthyroidism.(particularly in the developed countries). normally TSH combines with the surface receptors of thyroid cells and causes the synthesis and secretion of thyroid hormones. in Grave's disease the thyroid stimulating autoantibodies (B-TSAB) produced by B lymphocytes activate the TSH receptors and increase the secretion of thyroid hormones(thyroxine and triiodothyronine). Grave's disease is due to elevated thyroid stimulating IgG also knoen as long acting thyroid stimulator (LATS) which activates TSH and, thereby, increases thyroid hormonal production.
ACTH secretion or release is elicited by hypothalmic CRH (Corticotropin-releasing hormone.)
The glandular secretion is associated with pocrine, holocrine, and merocrine.
There are 2 hormones that regulate the secretion of follicle stimulating hormone (FSH):activin = stimulates (or "activates") the secretion of FSHinhibin = inhibits the secretion of FSH
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.
luteinizing hormone (LH)
Growth hormone, thyroid stimulating hormone, follicle-stimulating hormone, luteinizing hormone, prolactin, adrenocorticotropic hormone all require releasing hormones from the hypothalamus.
inhibin and estrogen in females, inhibin and testosterone in males
Thyroid stimulating hormone (TSH) stimulates the secretion of the hormones thyroxine (T4) and triiodothyronine (T3).
Anterior pituitary gland. It secretes Growth hormone,Thyroid stimulating hormone,Adrenocorticotrophic hormone, Follicle stimulating hormone,Leutenizing hormone,Prolactin hormone.
FSH stimulates spermatogenesis and development of graafian follicles.LH stimulates secretion of sex hormones,emmits ova and turn graafian follicle into corpus luteum.
The interstitial cell-stimulating hormone stimulates ovulation in the female and production of the female sex hormone progesterone. In the male, it stimulates the secretion of testosterone.
Follicle-stimulating hormone (FSH), luteinizing hormone (LH), and thyroid-stimulating hormone (TSH) are similar glycoproteins. FSH and LH are also called gonadotropins because they stimulate the activities of the gonads.TSH promotes normal development of the thyroid gland and the production of thyroid hormones.Adrenocorticotropic hormone (ACTH) is a peptide hormone that stimulates the production and secretion of steroid hormones by the adrenal cortex.signals to the brain stimulate release of an anterior pituitary tropic hormone. The tropic hormone then acts on its target endocrine tissue, stimulating secretion of a hormone that exerts systemic metabolic or developmental effects.
In the late maturation follicular phase, the dominant follicle level secretion of estrogen crosses a certain threshold stimulating Luteinizing Hormone (LH) secretion, which in turn stimulates more estrogen production by the follicle. The result is a rapid increase in LH secretion, the LH surge, and therefore triggers the rupture of the dominant follicle, in other words, ovulation.
There are a few hormones that act on the gonads and they are different for both the male and female reproductive systems.In females, the gonads are the ovaries. The hormones include:Estrogen - This promotes the production of secondary sex characteristics and sex drive.Progesterone - This hormone helps prepare the uterus for pregnancy.Inhibin - This hormone inhibits the secretion of follicle stimulating hormone.In males, the gonads are the testes. Their corresponding hormones include:Testosterone - This stimulates spermatogenesis, growth, and maturation of sperm as well as the production of secondary sex characteristics.Inhibin - This hormone inhibits the secretion of follicle stimulating hormone.
