Reproductive System Flashcards
primary sex organs
Gonads
Give the gonads of both male and female
Testes in males
Ovaries in females
the purpose of gonads
Gonads produce gametes (sex cells) and secrete hormones
Sperm—male gametes
Ova (eggs)—female gametes
Anatomy of the Male Reproductive System
Testes
Duct systems
Accessory Glands
External Genitalia
parts of the Duct system in male
Epididymis
Ductus (vas) deferens
Urethra
parts of the Accessory organs in male
Seminal glands (vesicles)
Prostate
Bulbourethral glands
Coverings of the testes
Tunica albuginea
Septa
capsule that surrounds each testis
Tunica albuginea
extensions of the capsule that extend into the testis and divide it into lobules
Septa
Each lobule contains _______ seminiferous tubules
one to four
The duct system transports sperm from the body and includes:
Epididymis
Ductus deferens
Urethra
Found along the posterior lateral side of the testis
Epididymis
The Epididymis is a highly convoluted tube with a length of _____ long
6 m (20 ft)
Temporary storage site for immature sperm
Epididymis
Path of the semen
Seminiferous tubule-Rete testis-Epididymis-Vas Deferens
Runs from the epididymis via the spermatic cord through the inguinal canal and arches over the urinary bladder
Ductus (vas) deferens
end of the ductus deferens, which empties into the ejaculatory duct
Ampulla
passes through the prostate to merge with the urethra
Ejaculatory duct
smooth muscle in the walls of the ductus deferens create peristaltic waves to squeeze sperm forward
Ejaculation
cutting of the ductus deferens at the level of the testes prevents transportation of sperm (form of birth control)
Vasectomy
Extends from the base of the urinary bladder to the tip of the penis
Carries both urine and sperm
Sperm enters from the ejaculatory duct
Urethra
enumerate the three Urethra regions
Prostatic urethra
Membranous urethra
Spongy (penile) urethra
surrounded by prostate gland
Prostatic urethra
prostatic urethra to penis
Membranous urethra
runs the length of the penis to the external urethral orifice
Spongy (penile) urethra
