Document Summary
Pitch of voice (men have more prominent laryngeal prominence) Ducts transport, store and assist in maturation of sperm. Accessory glands secrete most of the semen volume: provide sugars, buffers, enzymes support semen. Penis is the copulatory organ, contains the urethra (passage for semen and urine) Tests inside scrotum: normally, one lower than other (from development) Root of penis: attachment of penis to anterior body wall, penis= extra abdominal organ. Spermatic cord: connects inside nerves, vessels to outside. Responds to temperature change: normal sperm requires temps 2-3 degrees below body temp, cold: testes/scrotum pulled closer to body (cremaster and dartos contract, warm: scrotal skin flaccid and loose (away from body) Skeletal muscles bands that extend from internal oblique. Inside scrotum skin, contracts to pull closer to body (middle layer) Descends through spermatic cord to surround testis. Wrinkle the skin, creates rougher surface (reduces heat loss)
