CH 9 Flashcards
bulbourethral gland
pair of exocrine glands near the male urethra. secrete fluid into urethra
cowper gland
bulbourethral glands
ejaculation
ejection of sperm and fluid from the male urethra
ejaculatory duct
tube through which semen enters the male urethra
epididymis, epididymides
one of a pair of long tightly coiled tubes above each testis. stores and carries sperm from seminiferous tubules to the vas deferens
erectile dysfunction
inability of an adult male to achieve erection; impotence
flagellum
hair-like projection on a sperm cell that makes it motile (able to move)
fraternal twins
two infants resulting from fertilization of two separate ova by two separate sperm cells
glans penis
sensitive tip of the penis; comparable to the clitoris in the female
identical twins
two infants resulting from division of one fertilized egg. conjoined twins are incompletely separated identical twins
impotence
inability of an adult male to achieve erection
interstitial cells of the testis
specialized cells that lie adjacent to the seminiferous tubules in the testes
parenchyma
essential distinctive cells of an organ. they produce sperm
perineum
external region between anus and scrotum in the male
prepuce
forskin
prostate gland
exocrine gland at the base of the male urinary bladder
scrotum
external sac that contains the testes
semen
sperm cells and seminal fluid, discharged from the urethra during ejaculation
seminal vesicle
paired sac-like exocrine glands that secrete fluid into the vas deferens
seminiferous tubules
narrow, coiled tubules that produce sperm in the testes
spermatozoon, spermatozoa
sperm cells
sterilization
procedure that removes a person’s ability to produce or release reproductive cells; removal of testicles, vasectomy, and oophorectomy are sterilization procedures
stromal tissue
supportive, connective tissue of an organ, as distinguished from its parenchyma, also called stroma
testis, testes
male gonad that produces sperm
testosterone
hormone secreted by the interstitial tissue of the testes; responsible for male sex characteristics
vas deferens
narrow tube carrying sperm from the epididymis toward the urethra also called ductus deferens
