Pituitary Gland secretions and their functions Flashcards
which pituitary lobe releases both growth hormone(GH) and prolactin(PRL)
anterior lobe
which pituitary lobe releases both thyroid stimulating hormone(TSH) and adrenocorticotropic hormone(ACTH)
anterior lobe
which pituitary lobe secretes both follicle stimulating hormone(FSH) and luteinising hormone(LH)
anterior lobe
which pituitary lobe secretes both oxytocin and antidiuretic hormone(ADH)
posterior lobe
which of the pituitary gland hormones are peptides
Prolactin, Adrenocorticotropic hormone, Oxytocin and Antidiuretic hormone
which of the pituitary gland secretions are proteins
growth hormone
which of the pituitary gland secretions are glycoproteins
thyroid stimulating hormone, follicle stimulating hormone and luteinising hormone
what is the function of the growth hormone(GH)
promotes growth of body tissues
what is the function of prolactin(PRL)
promotes milk production from mammary glands
what is the function of thyroid stimulating hormone(TSH)
stimulates thyroid hormone release from thyroid
what is the function of adrenocorticotropic hormone(ACTH)
stimulates hormone release by adrenal cortex
what is the function of follicle stimulating hormone(FSH)
stimulates gamete production in gonads
what is the function of luteinising hormone(LH)
stimulates androgen production by gonads
what is the function of antidiuretic hormone(ADH)
stimulates water reabsorption in kidneys
what is the function of oxytocin
stimulates uterine contractions during childbirth
what is the role of the hypothalamus in pituitary gland secretions
secretes releasing or inhibitory hormones to stimulate or prevent secretion from anterior lobe
briefly describe the hypophyseal portal system
hypothalamic neurones secrete releasing or inhibitory hormones, then hypophyseal portal veins carry hormones to 2nd capillary bed of anterior pituitary
