The primary sex organs of the male are the two testes (sing. - testis), sometimes referred to as testicles. The testes are enclosed in an external pouch, the scrotum.

Lying over the superior and posterior surfaces of a testis is an elongated organ, the epididymis, where sperm are stored.

During ejaculation (ejection of the sperm) the sperm are propelled from the epididymis through the vas deferens. The vas deferens, blood vessels, nerves, lymphatic vessels, and the cremaster muscle make up the spermatic cord.

The vas deferens continues over the symphysis pubis and bladder into the pelvic cavity. The vas deferens joins a duct from the seminal vesicle to form the common ejacula-tory duct. This duct passes through the prostate gland and empties into the urethra.

The prostate gland, two seminal vesicles, and two Cowper's glands are secondary sex glands of the male. The Cowper's glands secrete into the urethra at the base of the penis.

The penis consists of three cylinders of spongy erectile tissue. The two upper cylinders are the corpora cavernosa. The longest of these cylinders is the corpus spongiosum (corpus = L. body). The corpus spongiosum contains the urethra. The distal end of the corpus spongiosum is enlarged to form the cone-shaped glans penis. A flap of skin called the prepuce or foreskin covers the glans in uncircumcised males.

Exercise 36.1

Correctly label Figure 36.1. Exercise 36.2

Identify the following structures on the model of the male reproductive system: common ejaculatory duct, corpus cavernosum, corpus spongiosum, Cowper's gland, epididymis, glanspenis, prepuce, prostate gland, scrotum, seminal vesicle, spermatic cord, symphysis pubis, testis, ureter, urethra and vas deferens.

Renal Fascia Around Kidney

Exercise 36.2

Cat dissection: urinary and reproductive systems. Using Figure 362 as a guide locate the following structures of the urinary system in the cat: urinary bladder; kidneys, renal artery, renal vein, ureters, and urethra.

Locate the penis. The sheath around the penis is the prepuce. Pull back the prepuce to expose the glans penis which is covered with papillae.

Carefully cut away the scrotum to expose the testis within a sac of fascia. Locate the epididymis.

Trace the vas deferens of the spermatic cord to the body wall, through the inguinal canal\ past the bladder; and into the penis near the prostate gland.
