The stretch reflex in a skeletal muscle is initiated because of nerve impulses arising from an organ embedded in the muscle called .

Muscle spindles

Explanation:

Muscle spindles are stretch receptors thst has both the sensory abd motor components ĺocated in the body of a muscle that basically signals on alterations in the muscle length. They transfer the length information to the central nervous system through the afferent nerve fibers. It fasten the motor neurons through the stretch reflex to prevent muscle stretch. Muscle spindles are sensory receptors that are majorly found in the muscle.
