what are muscle sensory receptors
Muscle spindles are sensory receptors within the belly of a muscle that primarily detect changes in the length of this muscle.They convey length information to the central nervous system via sensory neurons.This information can be processed by the brain to determine the position of body parts.he spindle is a stretch receptor with its own motor supply consisting of several intrafusal muscle fibres. The sensory endings of a primary (group Ia) afferent and a secondary (group II) afferent coil around the non-contractile central portions of the intrafusal fibres.
