Question

Proximal centriole of sperm is found in

• A. Head
• B. Neck
• C. Middle piece
• D. Tail

Answer 1

The correct option is B Neck

A male sperm contains a head, neck, a middle piece, and the tail. The sperm head contains an elongated haploid nucleus whereas the neck contains a proximal centriole i.e. reduced centrosome which remains intact during the spermatogenesis. The middle piece contains numerous mitochondria which produce energy for the movement of pain and facilitate sperm motility.

So, the correct option is 'Neck'.
