Going from the outside to the inside of a seminiferous tubule, what will you pass through?
Basement membrane Spermatogonia Sertoli cell Spermatocyte Spermatid Sperm
Spermatogenesis can be divided into three stages: ________________.
- proliferative
- meiotic (producing spermatids)
- spermiogenesis (producing sperm)
Which type of spermatogonia is self-regenerating?
Type Ad (on the periphery of the tubule, near the basement membrane)
Trace the number of chromosome sets in developing sperm.
Spermatogonium: one cell; 2n (Mitosis) Primary spermatocyte: one cell; 4n (Meiosis I) Secondary spermatocyte: two cells; 2n (Meiosis II) Spermatid: four cells; 1n (Spermiogenesis) Sperm: four cells; 1n
Meiosis I goes from ______________ to _____________.
primary spermatocytes; secondary spermatocytes

The mitochondria in sperm are located in _______________.
the midpiece
Anatomists divide the epididymis into three sections. What function does each serve?
