Biol 473 Theory Exam 2 UPDATED
ACTUAL Exam Questions and CORRECT
Answers
primary pathology - CORRECT ANSWER -problem with secretion in target gland
secondary pathology - CORRECT ANSWER -problem with secretion of trophic hormone
hypothalamic pituitary gonad axis pathway - CORRECT ANSWER -Hypothalamus
releases GnRH
GnRH signals pituitary gland to release LH and FSH (inhibits GnRH)
LH targets gamete production(females)
LH targets endocrine cells that release steroid and peptide hormones
FSH targets gamete production
moderate estrogen/androgen feedback effect - CORRECT ANSWER -negative feedback
on GnRH
high androgen feedback effect - CORRECT ANSWER -negative feedback on GnRH
high estrogen feedback effect - CORRECT ANSWER -positive feedback on GnRH
low estrogen/androgen feedback efect - CORRECT ANSWER -no negative/positive
feedback on GnRH
GnRH increases
Estrogen functions for sex characteristics - CORRECT ANSWER -secondary sex
characteristics: breast development, fat deposition
, cause of postmenopausal vaginal wall thinning - CORRECT ANSWER -decrease in
estrogen levels
Rats cycle - CORRECT ANSWER -4 day estrous cycle
FSH and LH function - CORRECT ANSWER -stimulates ovulation and production of
estrogen
Progesterone/estrogen function - CORRECT ANSWER -regulate production of GnRH,
FSH, and LH
also prepare and maintain uterus for implantation
renal pelvis - CORRECT ANSWER -connects to renal pyramids
renal cortex - CORRECT ANSWER -surrounds renal medulla
Nephron function - CORRECT ANSWER -filtration: movement from blood to lumen
reabsorption: lumen to blood
secretion: blood to lumen
excretion: lumen to outside of body
Where does blood filtration occur - CORRECT ANSWER -glomerular capsule
Proximal convoluted tubule functions - CORRECT ANSWER -reabsorption of water,
ions, and organic nutrients
Distal convoluted tubule functions - CORRECT ANSWER -secretion of ions, acids, drugs,
and toxins
