Q

Smooth Muscle

Surround each crus; contraction of these during arousal elvates the shaft & glans of the penis.

Also help with erection and ejaculation

57
Q

Discharges urine from the bladder & semen from the internal reproductive glands; enters the rrot of the penis & travels its lenght to emerge at the tip of the glans.

A

Urethra

58
Q

62
Q

Scrotum

A

Scrotal Sac - a loose bag of skin that hangs down behind the penis and contains the two testicles.

It posses lots of sweat glands that help to regulate the temperature of the scrotal contents.

Notes: the testes, inside look like the brain cortex. The are folded.

Sperm can also be store here

A

Epididymis

66
Q

Tunica Vaginalis

A

It is 4cm long

68
Q

carries mature sperm away from the epididymus; w/n spermatic cord

A

Vas deferens

71
Q

Temperature range for producing sperm

A

4-7C (7-12F) below core body temperature

72
Q

A

internal structure of the testes; fine, convoluted tubes that are the site of sperm production, or Spermatogenesis through meiosis.

It looks like the cortex of the brain

73
Q

The more testosterone the more production of sperm.

So what happens when you have “extra” sperm?

A

The body will produce estrogen to bring the production of sperm down.

So when a person is taken extra testosterone (steroids) the body could, in theory, become more feminine.
