Reproductive health/Glandular system
Exocrinology
[edit | edit source]Exocrine organs are glands with ducts.
Mammary gland and montgomery's glands are two exocrine organs.
Endocrinology
[edit | edit source]Endocrine organs are ductless glands.
Hypothalamus
[edit | edit source]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 | edit source]There is a link connecting the posterior pituitary to the anterior by a vein and to the hypothalamus.
Anterior (adenohypophysis)
[edit | edit source]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 | edit source]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 glands
[edit | edit source]Glucocorticoids are produced by the adrenal glands.[2]
Corpus luteum
[edit | edit source]The corpus luteum is a temporary endocrine organ that produces progesterone which is signaled by prolactin.[5]
