sagittal section

Front-to-back vertical section on the median line of the body.

peritoneum

Resistant membrane covering the internal walls and organs of the abdominal cavity and maintaining its shape.

abdominal cavity

Lower portion of the trunk containing the majority of the organs of the digestive, urinary and genital systems.

urinary bladder

Muscular reservoir where urine from the kidneys collects before being evacuated through the urethra.

prostate

Gland secreting a thick whitish liquid that aids in the formation of sperm and contributes to the mobility of the spermatozoa.

symphysis pubis

Slightly movable fibrocartilaginous joint connecting the two pubes (anterior part of the two iliac bones).

cavernous body

Erectile tissue of the back of the penis extending to the gland.

male urethra

Membranous duct enabling evacuation of urine and carrying sperm to the terminal part of the penis.

penis

Organ enabling copulation as well as the evacuation of urine and sperm; during sexual arousal, it fills with blood and forms an erection.

glans penis

Bulging anterior terminal portion of the penis consisting of a spongy body; it is surrounded by the prepuce and is where the meatus of the urethra opens.

foreskin

Cutaneous fold covering the glans penis.

urinary meatus

Outer orifice of the urethra enabling evacuation of urine and sperm.

scrotum

Cutaneous muscular pouch containing the testicles and regulating their temperature.

testicle

Male genital gland that produces spermatozoa and the sex hormone testosterone.

epididymis

Small organ in which sperm produced by the testicles is stored and undergoes maturation; it is connected to the deferent duct.

thigh

Section of the leg between the hip and the knee; it contains many powerful muscles.

bulbocavernous muscle

Muscle contributing to erection and to the evacuation of urine and sperm.

Cowper’s gland

Organ secreting a viscous substance emptying out into the urethra just before ejaculation to lubricate and to neutralize the acidity of residual traces of urine.

buttock

Fleshy part consisting mostly of muscles located at the base of the back.

anus

Terminal orifice of the digestive tract enabling ejection of fecal matter.

ejaculatory duct

Muscular membranous duct extending the deferent canal and opening into the urethra in the prostrate gland.

rectum

Terminal section of the large intestine preceding the anus.

seminal vesicle

Enlargement of the deferent duct whose glands secrete a protein-rich viscous liquid that makes up about 60% of the sperm.

deferent duct

Muscular membranous duct channeling the sperm of the epididymis to the prostate gland; it extends through the ejaculator duct.
