gamma motoneurons
They measure the rate of change of length of a muscle.
Proprioceptors, stretch-reflex receptors.
Muscle spindles are sensory receptors that monitor muscle tone. They are located within the muscle belly and are sensitive to changes in muscle length and stretch, providing feedback to the central nervous system about the state of muscle contraction.
Muscle spindles are the fibers in skeletal muscles that are stimulated by the degree of stretch. These specialized sensory organs detect changes in muscle length and contribute to the stretch reflex, helping to maintain posture and control muscle contraction.
The knee-jerk reflex is a type of stretch reflex, which is a type of spinal reflex. It involves the stimulation of sensory neurons in the muscle spindles of the quadriceps muscle, leading to a quick contraction of the muscle in response to a sudden stretch.
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.
It's called the stretch reflex and involves muscle spindles which are sensorimotor organs located in skeletal muscle.
The myotatic reflex is provoked by activation of muscle spindles in a stretched muscle. These muscle spindles are sensory receptors that detect changes in muscle length and help regulate muscle contraction and body position. When a muscle is stretched, the muscle spindles send signals to the spinal cord, leading to a reflex contraction to prevent overstretching.
Increased pliability of muscles: muscle spindles are located within muscle fibres. When muscle spindles are stretched the nerve impulses are made and information relative to the degree of stretch is sent to the nervous system. It then sends the messages back concerning how many motor units should be contracted in order to have a smooth movement. When your body is used to steady state exercise the more efficient your muscles spindles become at transmitting information, and the more pliable muscles become
