Penis
|
Male external genitalia, the ertile, erotically sensitive organ in males; its functions include sexual pleasure, delivery of semen, and unrination
|
|
|
Glans penis
|
The terminal know of the penis ("head")
|
|
|
Penis shaft
|
External elongated portion of the penis that contains 3 erectile structures, 2 corpa cavernosa and a singel corpus spongiosum
|
|
|
Foreskin (or prepuce)
|
The loose skin that partially or completely covers the glans in males who have not been circumcised
|
|
|
Smegma
|
A whitish greasy secretion that builds up under the foreskin of the penis
|
|
|
Cavernous bodies (Corpus Cavernosa)
|
Either of two elongated erectile structures within the penis, which extend backward into the pelvic floor
|
|
|
Spongy body ( Corpus Sponsiosum)
|
A single midline erectile structure. In both sexes it fills the glans; in Males it extends backwards along the underside of the Penis, surrounding the Urethra
|
|
|
Urethra and the Urethral Opening
|
The tube that conveys urine from the bladder to the Urethral Opening. It also serves for the discharge of semen
|
|
|
Root
|
Both the Corpora Cavernosa and the Coprus Spongiosum extend backward into the body under the pubic bones forming the root. The root is about 2 inches long and consists of two diverging crura, the backward extensions of the Corpura Cavernosa, and a central bulb, the backward extension of the Corpus Spongiosum.
|
|
|
Corona
|
The rim of the glans of the Penis, erotically sensitive nerve endings
|
|
|
Frenulum
|
A strip of loose skin on the underside of the Penis, running between the glans and the shaft. Highly sensitive.
|
|
|
Scrotum
|
The sac behind the Penis that contains the Testicles, and can be sexually arousing
|
|
|
Teste or Testicle
|
The male gonad: one of the two glands within the scrotum that produce sperm and secrete sex hormones. Egg shaped.
|
|
|
Seminiferous Tubules (where sperm develop)
|
Dominate the internal structure of the testicle. A set of about 1,000 narrow convoluted tubes that are site of sperm production (spermatogenesis)
|
|
|
Sperm
|
Hundreds of millions produced per day; a male gamete, produced in the testicles
|
|
|
Interstitial cells (Leydig Cells)
|
Produce testorone, cells are located between the seminiferous tubules in the testicle and secrete hormones
|
|
|
Epidiymis (2 behind testes)
|
a structure attached to each testicle where sperm mature and are stored before entering the Vas Deferens
|
|
|
Vas Deferens (2)
|
Either of 2 bilaterial ducts that convey sperm from the epididymis to the ejaculatory duct. Cut in Vasectomy
|
|
|
Ejaculatory Ducts (2)
|
Located inside the Prostate gland. Either of two bilaterial ducts formed by the junction of the Vas Deferns and the duct of the seminal vesicle. The ducts empty into the Urethra within the prostate
|
|
|
Prostate gland
|
A single gland, located at the base of the bladder, that surrounds the Urethra; its secretions ware component of semen
|
|
|
Seminal Vesicles(2)
|
Two glands situated to either side of the prostate, their secretions are a component of semen.Not storage areas for Semen, but add their own secretions
|
|
|
2 bulbourethral (Cowpers) glands
|
Two small glands near the root of the penis, whose secretions ("pre-cum") may appear at the Urethral Opening during sexual arousal prior to ejaculation
|
|
|
Semen (term for total ejaculate or "cum")
|
The thick, cloudy, off white liquid that is expelled from the male urethra at sexual climax. Most important component is the sperm and between 100 million and 700 million sperm are found in a single ejaculate, however it only occupies about 1% of the total make-up for Semen
*Prostate secretion is a cloudy alkaline fluid and a major component of semen |
|
|
Breasts, nippples (papilla mammae), areola
|
1/3 of men do enjoy arousal from the stimulation of their breasts
|
|
|
Spermatic Cord
|
The testicles "life-line". A bundle of structures that connect the testes to Organ systems within the abdominal cavity.
The Vas Deferns(Vas) is a tube that runs through each spermatic cord storing and carrying mature sperm away from the epididymis The ejaculatory duct is formed by the junction of the Vas Deferns of Seminal Vesicle and empties into the Urethra within the Prostate |
