Runs the length of the penis from the bladder to the meatus
Uretha
The flaccid penis fills with _______ during arousal, Causing an erection and allowing for the function of copulation/intercourse
Blood
A lubricant, ________, is produced under the prepuce on the penis
Smegma
It covers the glands or head that is filled with nerve endings
Foreskin
The oval shape testes are located in the __________________
Scrotum
Each oval shape does testes or epididymis are divided into_________
250 lobules
Coiled within the lobure are_______________where the sperm are formed
Seminiferous tubes
Mature sperm are stored in the______
Epididymis
A tube 13 to 20 feet in length, coiled and lying on the side of each testicle
Epididymis
Covering the head of the sperm that contains enzymes that help it penetrate the ova
Acrosome
Supplies energy for the sperm
Midpiece
The tail or__________provide motility
Flagellum
Sperm carry either an___or___chromosome
X or Y
Our muscular tubes transporting sperm from the Epididymis to the seminal vesicles
Vas deferens
The _________ produce a slightly alkaline Fluid that mixes with the sperm and becomes part of the semen ejaculated it during the male orgasm
Seminal vesicles
It protects the sperm from the acidity of the urethra
Seminal vesicles
Also Secretes an alkaline fluid that mixes with the sperm as part of the semen
Prostrate Gland
Produce another mucous Alkaline secretion in the urethra excreted from the glands just before the ejaculation
Cowper’s/ bulbourethral glands
Produces sperm cells
testis
Sack of the skin that holds the testis
Scrotum

Penis
Vas deferens
Carries sperm from testes to urethra
Urethra
Carries sperm and urine out of the body
Secretes a fluid that makes up most of the components of the semen
Seminal vesicle
Prostate gland
Secretes a slightly alkaline milky fluid that is discharged as part of the semen
Bulbourethral gland
Secretes a thick and clear mucus that lubricates and neutralize that any trace of acidic urine in the urethra
- Sympathetic fibers innervate smooth muscle of ductus deferens
-Produces forceful peristaltic contractions of smooth muscle of the ductus deferens
-Peristalsis propels perm and seminal fluid out distal end of urethra
Ejaculation
-parasympathetic function
- stimulates Dilation of penis blood vessels -causing engorgement of penis with blood
Erection
-Conscious thoughts (cerebral cortex) Stimulate correction center in the hypothalamus this in turn causes vasodilation or penile arterioles
-Reflux stimulation of Sacral plexus in infants and sleeping adult males (very common in dream states)

Follicles
Each egg is called
Ovum
After the follicle ruptures, it becomes a mass of yellow cells called the
