GENERAL HISTOLOGY

Detailed explanation-1: -The stretch reflex or myotatic reflex refers to the contraction of a muscle in response to its passive stretching by increasing its contractility as long as the stretch is within physiological limits.

Detailed explanation-2: -The myotatic reflex is the “knee-jerk” reflex in which a muscle contracts in direct response to its stretch. It is typically elicited by tapping on the tendon of a muscle, which deforms the tendon and stretches the muscle.

Detailed explanation-3: -The stretch reflex (myotatic reflex), or more accurately “muscle stretch reflex", is a muscle contraction in response to stretching within the muscle. The reflex functions to maintain the muscle at a constant length.

Detailed explanation-4: -The Spinal and Peripheral Motor System The stretch reflex consists of a monosynaptic response from the direct connection between Ia afferents and motor neurons, that may be followed by polysynaptic reflex activity.

Detailed explanation-5: -If a muscle is stretched (lengthened) too far or too quickly the muscle spindles are excited and the stretch reflex is activated, which causes the muscles to contract, thereby protecting the muscle from being over stretched or torn.
