chapter 18.2 Flashcards
what is hormone secretion controlled by
signals from the nervous system, chemical changes in the blood and regulated by negative feedback systems
what is the major integrating link between the nervous and endocrine system?
hypothalamus
where is the pituitary gland located
in the sella turcica of the sphenoid bone
the anterior pituitary gland secrete
human growth hormone
thyroid stimulating hormone
follicle stimulating hormone
prolactin
adrenocorticotrophic hormone
melanocyte stimulating hormone
what supplies blood to the anterior pituitary
the superior hypophyseal arteries
what is the most plentiful anterior pituitary hormone
human growth hormone
acts indirectly on tissues by secretion of insulinlike growth factors
what is a symptom of excess human growth hormone
hyperglycemia
TSH regulates the _______ and is controlled by ____
thyroid gland, TFH or thyrotropin
Follicle stimulating hormone
starts secretion of estrogen in the ovaries and sperm production in the testes
luteinizing hormone stimulates
progesterone secretion, estrogen secretion to start ovulation and corpus luteum formation
interstitial cells to secrete testosterone
prolactin
maintains milk secretion in mammary glands
ACTH controls the production of
glucocorticoids by the adrenal gland cortex
the posterior pituitary gland stores and releases
oxytocin and anti diuretic hormone
OT & ADH
oxytocin stimulates the
contraction of the uterus and ejection of breast milk
ADH stimulates
