Reproductive health/Glandular system

ExocrinologyEdit

Exocrine organs are glands with ducts.

Mammary gland and montgomery's glands are two exocrine organs.

EndocrinologyEdit

Endocrine organs are ductless glands.

HypothalamusEdit

The hypothalamus regulates hormone cycles. Neuroestradiol,[1] gonadotropin releasing hormone (GnRH) ,[2] and gonadotropin inhibitory hormone (GnIH)[2] are produced in the hypothalamus. Glucocorticoids produced by the adrenal gland due to stress promote GnIH and inhibit GnRh.[2]

Pituitary (hypophysis)Edit

There is a link connecting the posterior pituitary to the anterior by a vein and to the hypothalamus.

Anterior (adenohypophysis)Edit

Prolactin and melanocyte-stimulating hormone (MSH) are produced in the Anterior hypothalamus (adenohypophysis). MSH is responsible for pigments.

Thyroid-stimulating hormone (TSH) regulates the thyroid gland: its growth and its functions.[3]

Adrenocorticotropic hormone (ACSH) regulates the adrenal gland and provides its cue for the hormone regulation of cortisol.[3]

Follicle stimulating hormone (FSH) is responsible for estrogen.[3]Lutenizing hormone (LH) is also responsible for estrogen, along with testosterone, and progestin.[3] FSH and LH are gonadotrophins, and their production is controlled by either GnIH or GnRh.[4]

Somatotropin is responsible for overall growth.[3]

Posterior (neurohypophysis)Edit

The hypothalamus regulates the posterior pituitary (neurohypophysis), which in turn regulates the anterior pituitary.[3] Oxytocin and vassopressin (ADH) are made here in the neurohypophysis.

Adrenal glandsEdit

Glucocorticoids are produced by the adrenal glands.[2]

Corpus luteumEdit

The corpus luteum is a temporary endocrine organ that produces progesterone which is signaled by prolactin.[5]
