Bnns502 - male reproductive system Exam
Questions With 100% Verified Answers
Tissue type, location and function of scrotum - answer✔skin and connective tissue, located at
base of penis. midline septum divides scrotum for each testi. regulates temperature of the testes
(2-3 degrees cooler than body temp)
function of cremaster muscle - answer✔pulls testes closer to pelvic floor
anatomy of internal testes - answer✔divided into lobules, lobules contain seminiferous tubules.
tissue type and function of seminiferous tubules - answer✔smooth muscle, push sperm and
testicular fluid towards epididymous
what two cell types inhabit seminiferous tubules - answer✔spermatogenic (germ cells) and
sustentacular
what is spermatogenesis and what two hormones facilitate this - answer✔formation of sperm
cells by meiosis in seminiferous tubules in lobules of testes (starts abt 14yo and 200-400 million
sperm produced p/d). follicular stimulating hormone and testosterone
functions of sustentacular cells (3) - answer✔provide nutrients and support of germ/sperm cells,
produce testicular fluid, control release of sperm into lumen of seminiferous tubule
sperm cell anatomy (4) - answer✔acrosome - enzyme filled cap structure on top of head
head/nucleus - flattened and pointed with 23 chromosomes
midpiece - contains mitochondria to provide energy for tail
tail - propels sperm
What does Gondatropin releasing hormone do - answer✔released from hypothalamus to anterior
pituitary gland, stimulates release of FSH and LH.
what roles do FSH and LH have in spermatogenesis - answer✔FSH - stimulates spermatogenesis
LH - releases testosterone from interstitial cells
