Male Reproductive System Flashcards
Gonads
Organs that produce gametes and hormones
Gametes
a reproductive cell of an animal or plant
Perineal Structures
External genitalia
testes
produce male gametes (spermatozoa)
1 Testis
2 Epididymis
3 Ductus Deferens (Vas Deferens)
4 Ejaculatory Duct
5 Urethra
What is the pathway of Spermatozoa?
Descent of the Testes
form from inside body cavity near the kidneys
Spermatic Cord
a bundle of nerves, ducts, and blood vessels connecting the testicles to the abdominal cavity.
Inguinal Canal
a diagonal passageway that connects the abdominal cavity to the groin
Pampiniform Plexus
a network of veins in the spermatic cord of the male reproductive system
Scrotal Cavities
a sac-like structure located in the perineum, the area between the anus and the scrotum
Tunica Vaginalis
a thin, serous membrane that surrounds and protects the testis
Dortos Muscle
layer of smooth muscle in dermis of scrotum
Cremaster Muscle
layer of skeletal muscle deep to dermis
Tunica Albuginea
a dense, fibrous connective tissue layer that surrounds the testis and ovary
Efferent Ductules
small, coiled tubules that carry sperm from the testis to the epididymis
Spermatogenesis
The process of sperm production
Begins at outmost cell layer in the seminiferous tubules
Name the five cells of Spermatogenesis
1 Spermatogonia
2 Primary spermatocytes
3 Secondary Spermatocytes
4 Spermatids
5 Spermatozoa
interstitial cells in testes
cells located between the seminiferous tubules that are primarily responsible for producing the male sex hormone testosterone
nurse cells in testes
Sertoli cells which are located within the seminiferous tubules and play a crucial role in supporting and nourishing developing sperm cells throughout the process of spermatogenesis
Spermiogenesis
Each spermatid matures into one Spermatozoon (Sperm)
Epididymis
Coiled tube at the start of the male reproductive tract
Epididymis Head
Recivies spermatozoa from efferent ductules
Epididymis Body
From last efferent ductule to posterior margin of testis
Epididymis Tail
Primary storage location of spermatozoa
