Muscle contraction
A reflex.
Proprioceptors are sensory nerve ending in muscles, tendons, and joints which respond to variations in movement, position, and tension. Muscle spindles proprioceptors sense changes in muscle length, Pacinian corpuscles are proprioceptor which detect changes in movement and pressure within the body, and the Golgi tendon organs, proprioceptors in the tendons near the end of muscle fibers, are sensitive to changes in muscle tension.
True
Muscle spindles primarily monitor muscle length and changes in muscle length, providing information about muscle stretch and contraction. Tendon organs, on the other hand, monitor muscle tension or the force of muscle contraction by detecting changes in tension within the tendons. Together, these sensory receptors help regulate muscle tone and protect muscles from injury.
The internal tendon bulk is thought to contain no nerve fibres, but the epitenon and paratenon contain nerve endings, while Golgi tendon organs are present at the junction between tendon and muscle.
golgi tendon organs
Three organs of the muscular system would be muscles, nerves, and blood vessels. If we included nerve receptors, then we could add Golgi tendon organs and muscle spindle cells.
It's called the stretch reflex and involves muscle spindles which are sensorimotor organs located in skeletal muscle.
Muscle spindles and golgi tendon organs. im not sure if there are more but those are the ones i know of
The Golgi tendon organ is a sensory receptor located at the junction of muscles and tendons. Its primary function is to monitor tension and force generated by muscle contractions. When muscle tension becomes excessive, the Golgi tendon organ sends signals to the central nervous system to inhibit further muscle contraction, thereby preventing potential injury. This reflex mechanism helps maintain muscle and tendon integrity during physical activity.
The Golgi tendon reflex is a protective mechanism that inhibits muscular contraction when excessive tension is detected in the tendon. During PNF stretching, activating the Golgi tendon organs through isometric muscle contractions can help to temporarily relax the muscle, allowing for a greater stretch to be achieved. This reflex helps to prevent injury by limiting the amount of force exerted on the muscle during stretching.
