Question

During spermiogenesis, nebenkern of the sperm develops from ________ of the spermatid.

Hint:

The nebenkern is essentially the "engine room" of the sperm, located in the middle piece.

Answer 1

Step 1: Spermiogenesis is the transformation of a non-motile spermatid into a motile spermatozoon.
Step 2: The mitochondria of the spermatid aggregate and twist around the proximal part of the axial filament in the middle piece.
Step 3: This spiral arrangement of mitochondria is specifically called the nebenkern, which provides energy (ATP) for sperm motility.
