Male Reproduction Flashcards
(24 cards)
Testes
produce sperm and testosterone
Epididymis
passageway of sperm from testes to vas deferens
Head of epididymis
sperm not capable of fertilization or motility
Body of epididymis
sperm gain motility
Tail of epididymis
storage site until ejaculation, sperm fertile and mobile
Vas Deferens
transport sperm from testes to penis
Accessory Sex Glands
secrete components of seminal fluid
Penis
fibroblastic or vascular type
Functions of the male
- produce and maintain supply of sperm
- detect females in estrus
- inseminate females and fertilize the female gamete
Term for produce and maintain supply of sperm
spermatogenesis
Spermatic cord contains:
vas deferens, pampiniform plexus, and external cremaster muscle nerves
Vas Deferens
transport sperm during ejaculation
Tunica Albuginea
connective tissue which holds testis together
Seminiferous tubule
sperm producing cells- true germinal epithelium
Rete Testis
function in sperm transport from seminiferous tubules- 100 tubules
Caput epididymis
function in maturation of spermatozoa, fluid absorption
Corpus epididymis
maturation of spermatozoa
Cauda epididymis
final maturation and storage, only sperm capable of fertilization
Efferent ducts
6-12 tubules absorb fluid
Scrotum
protection and temperature regulation
Leydig cells
source of testosterone
Seminiferous tubules
source of spermatazoa
Mediastinum
in center of testes, transport spermatozoa from lolbules within testes to epididymis
How do sperm travel through epididymis?
head, body, tail; they mature and gain motility as they move through
