Differences between annulospiral and flower ending?

Answer 1

Afferent innervation in the muscle

spindle :

a) Primary afferent:

That forms annulo-spiral endings to the central part of both nuclear bag and nuclear chain intrafusal muscle fibers. They are thick and rapidly conducting

b) Seconderyafferent:

That forms flower-spray endings on both sides of annulospiral endings in intrafusal muscle fibers. They are thinner and slower in conduction.

Answer 2

Annulospiral endings are primary sensory endings found in muscle spindles that wrap around the intrafusal muscle fibers, detecting the rate of muscle stretch. Flower-spray endings, on the other hand, are secondary sensory endings in muscle spindles that fan out and respond to muscle length. Both endings are important for proprioception and muscle control.
