Spermatogenesis question
Notice the cell labeled &quot;spermatid&quot; is still attached to the Sertoli cell. Once released from the Sertoli cell, spermatids are called spermatozoa.
This process (release of the spermatid to form a spermatazoon) is called spermiation
EDIT
The text you added is still correct, but not well explained. Spermiogenesis is the development of the spermatid, the haploid 1N gamete produced by the second meiotic division, into a cell with a long flagella with a small amount of cytoplasm. Spermiation is the release from the sertoli cell. Both spermiogenesis and spermiation are involved in the development of a spermatid to a spermatozoon, but the specific point where we stop calling them spermatids and start calling them spermatozoa is release by the Sertoli cell, or spermiation, a substantial process in its own right. Both spermiogenesis and spermiation are important steps in the conversion of the haploid 1N gamete to a motile, free spermatozoon.
