The stretch reflex (myotatic reflex), or more accurately "muscle stretch reflex", is a muscle contraction in response to stretching a muscle. The function of the reflex is generally thought to be maintaining the muscle at a constant length but the response is often coordinated across multiple muscles and even joints. [ 1 ]

2023年8月4日 · The muscle stretch reflex is the most basic reflex pathway in the body and as such, understanding this allows understanding of more complex reflexes. This article shall discuss the components of a reflex arc, the monosynaptic reflex and relevant clinical issues.

2024年10月2日 · The stretch reflex (also called the myotatic stretch reflex, the muscle stretch reflex and sometimes the knee-jerk reflex), is a pre-programmed response by the body to a stretch stimulus in the muscle.

2023年7月17日 · The stretch reflex is the contraction of a muscle that occurs in response to its stretch. It is not controlled by higher functioning centre i.e. the brain, and is a monosynaptic response that is transmitted to the spinal cord. Our body needs to …

2024年12月14日 · Muscle stretch reflexes in the biceps, triceps, knees, and ankles should be examined in all patients as part of a routine neurologic examination. Testing for clonus in the ankles should be performed when hyperreflexia is seen in the lower extremities.

2022年9月12日 · The monosynaptic stretch reflex, sometimes called the muscle stretch reflex or deep tendon reflex, is a reflex arc that facilitates direct communication between sensory and motor neurons innervating the muscle.

The muscle stretch reflex is a reflex arc that responds to stretching of muscle fibers to keep the muscle in an appropriate state of tension and tone, ready to contract or relax as needed. The sensory input (afferent) of the reflex is from two structures in the muscle called spindles and Golgi tendon organs .

The local circuitry within the spinal cord mediates a number of sensory motor reflex actions. The simplest of these reflex arcs entails the response to muscle stretch, which provides direct excitatory feedback to the motor neurons innervating …

2024年12月1日 · passively stretched, its fibers resist the stretch by contracting. Reflexes elicited by application of a stretch stimulus to either tendons or periosteum, or occasionally to bones, joints, fascia, or aponeurotic structures are usually referred to as muscle stretch or deep tendon reflexes. The reflex is caused by sudden muscle stretch,

2022年2月3日 · Based on the dynamic response of the primary endings to stretch: This reflex occurs while the muscle length is actually increasing, and is produced mainly as a result of the stretch of the nuclear bag fibers (rapidly adapting receptors).
