Spindle neuromusculaire
See also: Spindle, Neuromusculaire
The spindle neuromusculaire is a Mécanorécepteur consisted of muscle fibers modified. Parallel to had fibers the Muscle, it is sensitive to the lengthening of this one.
Role
Its role is to increase the level of contraction of the muscle in answer to its own stretching. The muscle tends to return to its initial length.
Constitution
Each spindle includes/understands three to ten small muscle fibers wrapped in a conjunctive fabric capsule.
Operation
They react during the lengthening of the muscle and slacken what creates a related nerve impulse going until the spinal-cord.
