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.

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 …

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.

The stretch reflex is defined as a neural reflex involving a receptor and effector neurone, which can be either phasic or tonic, and is responsible for muscle contraction in response to stretching stimuli. It plays a crucial role in maintaining posture and muscle tone.

2022年7月24日 · The stretch reflex is a type of reflex wherein the muscle contracts caused by the stimulation of the muscle proprioceptors. When the muscle is stretched, the reflex reaction is to resist the stretching.

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.

2023年5月23日 · The myotatic stretch reflex (MSR) is an involuntary muscle contraction that occurs in response to overly stretching a muscle. Special receptor cells called muscle spindles have the central role in this reflex, which is why the reflex is also called the muscle spindle reflex.

2020年9月21日 · In this Primer, we outline what is currently known about stretch reflex function and its underlying mechanisms, with a specific focus on how the cascade of nested responses collectively known as stretch reflexes interact with and build off of one another to support real-world motor behavior.

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 …
