MUSCLE PHYSIOLOGY

Detailed explanation-1: -Most vertebrates possess three basic types of proprioceptors: muscle spindles, which are embedded in skeletal muscles, Golgi tendon organs, which lie at the interface of muscles and tendons, and joint receptors, which are low-threshold mechanoreceptors embedded in joint capsules.

Detailed explanation-2: -Proprioception relies on two, primary stretch receptors: Golgi tendon organs and muscle spindles. Muscle spindles are sensory receptors within the belly of a muscle that primarily detect changes in the length of this muscle.

Detailed explanation-3: -Receptors of vision. The retinal is the principal molecule of vision in the retina. Receptors of hearing. Receptors of balance. Receptors of taste. Receptors of smell. Receptors on the skin.
