Lab Practical 3 Flashcards
Gonads of the male.
Testes
These cells produce testosterone.
Interstitial Cells
Sac in which the testes are suspended outside the body.
Scrotum
Muscle used to regulate the temperature of the testes.
Dartos
A cap of enzymes that covers the nucleus of the sperm cell.
Acrosome
Contributes to genetic variety in the offspring.
DNA crossing-over
A passageway in the groin area in which the testes descend during development.
Inguinal Canal
Slender ducts in the testes in which sperm are produced.
Seminiferous Tubules
Surgical sterilization of the male.
Vasectomy
Portion of the penis removed by circumcision.
Prepuce
Base that neutralizes the acid within the female vagina.
Spermine
Organ that serves to deposit semen in female vagina.
Penis
Process in which a sperm cell undergoes meiosis producing four spermatoza.

Spermatogonia
These cells provide nourishment to the sperm. Also called Sertoli.
Sustentacular Cells
Where it allows the sperm to penetrate and fertilize the egg.
Capacitation
Connective tissue that protects from the epididymis to the abdominal wall.
Spermatic Cord

Primary Spermatocyte
What is the second sperm cell division called?
Secondary Spermatocyte
DNA is located in the ____ sperm.
Head
These have digestive enzymes inside the sperm and it helps the sperm burrow into the egg.
Acrosome
This part of the sperm has mitochondria which provide the energy to help it swim.
Midpiece
This part of the sperm has the ______ which allows it to swim. It is located inside the tail.
