bnns502 - male reproductive system exam
study guide
tissue type, location and function of scrotum - Ans:✔✔-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 - Ans:✔✔-pulls testes closer to pelvic floor
anatomy of internal testes - Ans:✔✔-divided into lobules, lobules contain seminiferous tubules.
tissue type and function of seminiferous tubules - Ans:✔✔-smooth muscle, push sperm and testicular
fluid towards epididymous
what two cell types inhabit seminiferous tubules - Ans:✔✔-spermatogenic (germ cells) and sustentacular
what is spermatogenesis and what two hormones facilitate this - Ans:✔✔-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) - Ans:✔✔-provide nutrients and support of germ/sperm cells,
produce testicular fluid, control release of sperm into lumen of seminiferous tubule

sperm cell anatomy (4) - Ans:✔✔-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 - Ans:✔✔-released from hypothalamus to anterior
pituitary gland, stimulates release of FSH and LH.
what roles do FSH and LH have in spermatogenesis - Ans:✔✔-FSH - stimulates spermatogenesis
LH - releases testosterone from interstitial cells
3 functions of testosterone - Ans:✔✔-male sex organs (maintenance, development, functioning, growth)
protein synthesis, sperm maturation, bone growth
secondary male sex characteristics of puberty (hair, voice drop, oily skin, behaviour, libido, muscles,
bones)
interstitial cells location and function - Ans:✔✔-sit inbetween seminiferous tubules and release
testosterone when stimulated by LH
3 funtions of epididymus - Ans:✔✔-stores sperm, holds sperm while it matures and gains mobility,
propels sperm into ductus deferens during sexual arousal by peristalsis
