Question

What is the functional significance of annulus formation during spermiogenesis?

विकल्प

• Generates energy for sperm movement

• Provides structural support to the sperm

• Enables sperm to penetrate the egg

• Condenses the nuclear material

Answer 1

The annulus, formed as a ring-like structure between the middle piece and tail, provides critical structural support to the sperm. This anatomical feature acts as a reinforcing band that maintains the structural integrity of the sperm and ensures proper biomechanical function during flagellar movement through the viscous environment of the female reproductive tract.
