Document Summary
Spermatozoon (sing): the male sex cell (aka sperm cell) Sperm cell carries nuclear hereditary material/chromosomes in its head region. The tail consists of a flagellum, which makes the sperm cell mobile. Fraternal vs identical: fraternal: 2 completely separate pregnancies and they both happen at the same time, see slides for details about amnion stuff. Testis: inside scrotal sac (outside of body) Epididymis: on top of testis, sperm cells become motile here location for storage of sperm until time for ejaculation. Vas deferens: tube that runs from testis to pelvic region at level of urinary bladder, merging with ducts to form ejaculatory duct to get sperm out of body. Seminal vesicles: two glands located at base of bladder open to ejaculatory duct. Secrete semen: more about semen below! Prostate gland: secretes milky, white fluid that is a mix of sugars, enzymes, alkaline chemicals (nutritious for sperm cells) (alkaline chemicals promote survival of sperm in acidic environment of vagina)
