male reproductive system Flashcards
produce sprerm and sex hormone
Testis
pouch of skin and muscle that houses the testicles and helps regulate their temperature for sperm production.
Scrotum
Protective covering around testis
Capsule
Site of sperm production, known spermatogenesis
Seminiferous tubule
Collects sperm from seminiferous tubule
Rele testis
Stores and matures sperm
Epididymis
transports sperm from epididymis to ejaculatory duct
Ductus deferens
Produces seminal fluid providing energy and nutrients for sperm.
Seminal vesicle
Passage for sperm and seminal fluid to enter urethra
Ejaculatory duct
Secretes fluid to nourish and protect sperm
Prostate Gland
Passageway for urine and semen
Urethra
produces pre ejaculation fluid to lubricate urethra
bulbourethral gland
organ for sec and urination
penis
erectile tissue responsible for erection
Corpora cavernosa
supports urethra and maintains erection
corpus spongiosum
highly sensitive tip of penis
glans penis
protective covering of glans penis
Foreskin
Produces testosterone
Interstitial cell
Nurtures and supports developing sperm cells
Sertoli cell
Gives rise to sperm cell
Germ cell
type of germ cell found in the testes that gives rise to sperm cells through the process of spermatogenesis.
spermatogonium
a developing sperm cell that undergoes meiosis to produce haploid spermatids, which eventually mature into sperm cells.
spermatocyte
an immature sperm cell formed from a spermatocyte. It undergoes further maturation to develop into a fully functional sperm cell.
spermatid
_______________, or sperm cell, consists of three main parts:
Head: Contains the genetic material (DNA) necessary for fertilization.
Midpiece: Contains mitochondria that provide energy for the sperm’s movement.
Tail: Propels the sperm forward, allowing it to swim towards the egg for fertilization.
Spermatozoan
