ANATOMY AND PHYSIOLOGY OF MALE REP Flashcards
it is the body temperature regulator
scrotum
rugated, skin-covered, muscular, deeply pigmented pouch suspended from the perineum
scrotum
responsible for contraction of the scrotum
cremaster muscle
separates each sac
midline scrotum
it is inside the scrotum
testes
is responsible for the release of testosterone from leydig cells
luteinizing hormone
responsible for the release of androgen-binding protein (ABP) that combines with testosterone to promote sperm formation
follicle stimulating hormone
many preterm babies still have undescended testes or testes still remain in the pelvic cavity
cryptorchidism
3 cylindrical masses of erectile tissue in the penis shaft:
2 corpus cavernosa
1 corpus spongiosum
contains urethra which serves as a passage for both sperm and urine
corpus spongiosum
organ of copulation and urination
penis
organ of copulation and urination
penis
supplies blood to the penis
penile artery
erection is innervated by the
peripheral nervous system
a bulging, sensitive ridge of the tissue at the distal end of the penis; similar in function to the clitoris
glans penis
retractable casing of skin that protects the glans penis
prepuce
this is the cite of circumcision; surgically removed during circumcision; known as foreskin
prepuce
condition in which the prepuce is too tight that it interferes with the flow of urine
phimosis
a tightly coiled tube responsible for conducting sperm from the tubule to the vas deferens
epididymis
storage site of spermatozoa and semen
epididymis
sperm is capable of surviving for how many hours inside the woman’s body
72hrs
are two convoluted pouches that lie along the lower portion of the bladder and empty into the urethra by ejaculatory ducts
seminal vesicle
these glands secretes a viscous alkaline liquid with a high sugar, protein, and prostaglandin content
seminal vesicle
a chestnut-size gland that lies just below the bladder and allows the urethra to pass through the center of it, like the hole in the donut
prostate gland
an additional hollow tube surrounded by arteries and protected by a thick fibrous coating
spermatic cord
carries sperm from the epididymis through the the inguinal canal
vas deferens/ duct deferens
site severed durint the vasectomy to prevent passage of sperm
vas deferens/ duct deferens
lie beside the prostate gland and empty by short ducts into the urethra
bulbourethral gland/ cowper’s gland
they supply one more source of alkaline fluid to help ensure the safe passage of the spermatozoa
bulbourethral gland/ cowper’s gland
is a hollow tube leading from the base of the bladder which after passing through the prostate gland….
urethra
semen is derived from the
prostate gland (60%)
seminal vesicle (30%)
epididymis (5%)
bulbourethral glands (5%)
