Stretch Reflexes Provide Automatic Regulation of Skeletal Muscle Length

Question

Stretch reflexes provide automatic regulation of skeletal muscle length.

Accepted Answer

Stretch reflexes are a type of involuntary reflex that automatically regulate skeletal muscle length. When a muscle is stretched, the muscle spindles within the muscle detect the change in length and send signals to the spinal cord. The spinal cord then sends signals back to the muscle, causing it to contract and resist further stretching. This helps to maintain muscle tone and prevent overstretching or tearing of the muscle fibers.
