Male Reproductive System Flashcards
Sac of skin and superficial fascia that hangs outside the abdominopelvic cavity at the root of the penis
Contains paired testicles separated by a midline septum
External positioning keeps the testes 3*C lower than core body temperature
Scrotum
Thin layer of smooth muscle in the dermis
Contractions of this muscle causes wrinkling of the skin
Dartos muscle
A thicker layer of skeletal muscle that lowers and raises the testes based on temperature
Cremaster muscle
Each testes is enclosed by this
A continuation of the peritoneum that lines the abdominopelvic cavity
Tunica vaginalis
A fibrous capsule that covers each testis
Tunica albuginea
Microscopic coiled tubules that make up each testis
Formation of sperm cells (spermatogenesis) occurs
Seminiferous Tubules
Male reproductive organs or gonads
Testes
Storage and maturation area of sperm
Its head joins the efferent ductules and caps the superior aspect of the testis
Epididymis
The duct of the epididymis has stereocilia that:
1) absorb testicular fluid
2) pass nutrients to the sperm
Nonmotile sperm enter, pass through epididymis’ tubes and become motile propelled by what process?
Peristalsis
Contains the structures running from the testicles to the pelvic cavity
Passes through the inguinal canal
Spermatic cord
Contents of spermatic cord:
1) Vas Deferens
2) Nerves
3) Blood Vessels
Pea-sized glands inferior to the prostate
Produce alkaline mucus prior to ejaculation that neutralizes traces of acidic urine in the urethra
Bulbourethral gland/
Cowper’s gland
Tube-like organ which extends from the tip of urinary bladder to the tip of the penis
The duct transports and discharges both urine and semen
Urethra
Produce male hormones like testosterone and androgen
Intestinal Cells of Leydig
