The stretch reflex, or myotatic reflex, is provoked by activation of which of the following in a stretched muscle?

Question

Quizplus · Accepted Answer

The stretch reflex, also known as the myotatic reflex, is provoked by activation of muscle spindles in a stretched muscle. The muscle spindle is a specialized muscle fiber that detects changes in muscle length and sends signals to the spinal cord, triggering a reflexive contraction of the same muscle to resist further stretching. The Golgi tendon organ, on the other hand, is a sensory receptor located at the junction of the muscle and tendon that senses changes in muscle tension and helps regulate muscle activity. Therefore, the correct answer is A) muscle spindles.
