Male reproductive system Flashcards
Spermatozoon/Sperm cell
Male sex cell
Head of sperm cell carries
nuclear hereditary material or chromosomes
Flagellum
hair like projections - makes sperm cell move
Organs of male reproductive system are designed to ..
produce and release billions of sperm cells throughout a mans lifetime
Testosterone
hormone responsible for the male characteristics (bear, pubic hair, deeper voice)
Fraternal twins
Fertilization of two separate eggs by separate sperm cells `
Identical twins
result of a single fertilized egg splitting and forming two embryos
Prostate gland - location
under the bladder and surrounds the urethra
Epididymis
stores and carries semen - pair of long, tightly coiled tubes above each testis
seminiferous tubules
where sperm is formed
Scrotum
sac containing the male gonads (sperm cells)
bulbourethral glands
pair of exocrine glands near male urethra, cowper glands
ejaculatory duct
tube through which semen enters the male urethra
glans penis
sensitive tip of the penis
interstitial cells of the testes
produce testosterone, also called leydig cells
parenchymal tissue
Essential distinctive cells of an organ. EX. Seminiferous tubules within the testes
male perineum
region between anus and scrotum
prepuce
foreskin
seminal vesicles
paired sac like exocrine glands that secrete fluid into the vas deferens
Stromal tissue
Supportive, connective tissue of an organ, stroma
