Verified step by step guidance

Understand the function of stretch receptors: Stretch receptors are specialized sensory structures that detect changes in muscle length or tension. They play a critical role in proprioception, which is the body's ability to sense its position and movement.

Identify the role of muscle spindles: Muscle spindles are stretch receptors embedded within skeletal muscle fibers. They detect changes in muscle length and initiate reflexes to maintain muscle tone and posture.

Differentiate Golgi tendon organs: Golgi tendon organs are located in tendons and monitor tension generated by muscle contraction, not muscle length. They help prevent excessive force that could damage muscles or tendons.

Exclude Meissner's corpuscles and Pacinian corpuscles: Meissner's corpuscles and Pacinian corpuscles are mechanoreceptors found in the skin. Meissner's corpuscles detect light touch, while Pacinian corpuscles detect deep pressure and vibration. They are not involved in detecting muscle stretch.

Conclude that the correct answer is 'Muscle spindle': Based on the function and location of stretch receptors, muscle spindles are the correct type of stretch receptor embedded in skeletal muscle.
