Question | Answer |
4 duct that serve as passageways for sperm: epididymus, ejaculatory duct, ductus deferens, & | urethra |
external male genitalia | penis & scrotum |
male gonads that produce male sperm and male sex hormone | testes |
part of testes where sperm are produced | seminiferous tubules |
cells that produce testosterone | Leydig |
cells that support spermatogenesis, providing sperm nutrition and secreting inhibin and androgen-binding protein | Sertoli |
where do testes develop in the male fetus? | near the kidneys |
when testes descend during embryologic development from near the kidneys to the scrotum, what do they pass through? | inguinal canals |
why is complete descent of the testes necessary for normal sperm development? | too hot in body for sperm |
spermatic cord contain: ductus deferens, testicular artery, veins, autonomic nerves, lymphatic vessels and | cremaster muscle |
structure supporting the male reproductive system formed when testes descend from the posterior abdomen | spermatic cord |
Highly coiled tube located in the scrotum, site of final sperm maturation. | epididymus |
ductus (vans)deferens, ejaculatory duct, epididymus are all paired/unpaired passageways | paired |
The ________ ____ passes through the prostate in males. | ejaculatory duct |
vasectomy site | ductus deferens |
seminiferous tubules -> epididymus -> vas deferens -> | urethra |
sperm cells + seminal fluid = | semen |
paired glands: bulbourethral glands and | seminal vesicles |
male sex gland that secretes mucus | bulbourethral gland |
seminal vesicle empty into/come from the ejaculatory duct | empty into |
bulbourethral glands and seminal vesicles secrete | alkaline fluid |
glands add scretions to semen: seminal vesicles -> | bulbourethral glands |
circumcision removes the (foreskin) | prepuce |
male erection stimulus receptors | skin around and on the genitals |
male erection central integration center | sacral spinal cord |
male erection efferent pathway | parasympathetic fibers release nitrous oxide (NO) |
male erection effector and reflex response | smooth muscles relax which dilates blood vessels |
primarily a vascular response in penis (parasympathetic NS) | erection |
primarily a muscular response in penis (sympathetic NS) | ejaculation |
cytoplasmic changes that make structurally mature sperm cells; conversion of sprematids to spermatozoa | spermiogenesis |
mature sperm | spermatozoa |
46 to 23 | meiosis |
secondary spermatocytes and ________ have 23 chromosomes by meiosis | spermatids |
stem cells | spermatogonia |
LH stimulates _________ production | testosterone |
anabolic steriods act like/inhibit testosterone | act like |
