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 ]
This reflex is also called the inverse myotatic reflex, [4] because it is the inverse of the stretch reflex. GTOs' inhibitory effects come from their reflex arcs: the Ib sensory fibers that are sent through the dorsal root into the spinal cord to synapse on Ib inhibitory interneurons that in turn terminate directly on the motor neurons that ...
In biology, a reflex, or reflex action, is an involuntary, unplanned sequence or action [1] ... The myotatic or muscle stretch reflexes ...
The elicited response is compared with the reflex result of the same action when the maneuver is not in use. Often a larger reflex response will be observed when the patient is occupied with the maneuver: "A weak or apparently missing reflex could be triggered by afferent activity resulting from such muscle tension.
Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung; Hoffmann's reflex — also known as the finger flexor reflex; middle finger and thumb response. Test can indicate both neurological damage and nerve regeneration; often combined with the Babinski reflex test. Jaw jerk reflex
Joints are controlled by two opposing sets of muscles called extensors and flexors, that work in synchrony for smooth movement.When a muscle spindle is stretched, the stretch reflex is activated, and the opposing muscle group must be inhibited to prevent it from working against the contraction of the homonymous muscle.
Most people enter military service “with the fundamental sense that they are good people and that they are doing this for good purposes, on the side of freedom and country and God,” said Dr. Wayne Jonas, a military physician for 24 years and president and CEO of the Samueli Institute, a non-profit health research organization.
Liddell-Sherrington reflex Associated with Edward George Tandy Liddell and Charles Scott Sherrington, the Liddell-Sherrington reflex is the tonic contraction of muscle in response to its being stretched. When a muscle lengthens beyond a certain point, the myotatic reflex causes it to tighten and attempt to shorten.
