WebJul 13, 2024 · Abstract. Muscle spindles are encapsulated sensory organs found in most of our muscles. Prevalent models of sensorimotor control assume the role of spindles is to reliably encode limb posture and movement. Here, I argue that the traditional view of spindles is outdated. Spindle organs can be tuned by spinal γ motor neurons that … WebMuscle spindles and the stretch reflex Muscles are recruited through the activation of spindle cells, which are stretch receptors housed within the muscle belly. As the muscle is loaded, the muscle spindle stretches to match the extent of the load. The spindle then sends a signal to the spinal cord, which commands the same muscle to contract. perkspot used cars

Muscle spindle function in healthy and diseased muscle

WebWhen 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. This inhibition is accomplished by the actions of an inhibitor interneuron in the spinal cord. WebTone within skeletal muscle is controlled via a receptor called the MUSCLE SPINDLE. Therefore, to understand the control of tone it is imperative to understand function of the muscle spindle. The functional value of reflexes . The Stretch Reflex .
