Modified muscle fibers encased in a connective sheat and functioning as stretch receptors.
Organ in a muscle that senses changes in muscle length, especially stretches. Rapid stretching of the muscle results in messages being sent to the nervous system to contract the muscle, thereby limiting the stretch.
is an encapsulated sensory organ that lies within muscles and conveys information to the spinal cord as well as receiving a specific input from the anterior horn gamma-motorneuron. It is important in setting muscle tone, mediating the tendon stretch reflex, as well as providing useful proprioceptive information to the CNS
Structure in skeletal muscles containing small muscle fibers and sensory receptors activated by stretch.
The sensory organ within a muscle that is sensitive to stretch and thus protects the muscle from being stretched too far; Muscle spindles cause the muscle to contract instead of allowing it to stretch during rapid stretching.
An encapsulated sensory structure activated by stretch of skeletal muscles.
Specialized stretch receptor within skeletal muscle giving information on muscle length and rate of change of length; sensitivity can be modified by central nervous system. Responsible for stretch reflex.
Muscle structure is innervated by both sensory and motor neuron axons. Its functions are to send proprioceptive information about the muscle to the central nervous system, and to respond to muscle stretching.
