MUSCLE PHYSIOLOGY

Detailed explanation-1: -Free nerve endings are formed by branching terminations of sensory fibers in the skin. The endings are slightly thickened. Although mechanoreceptors, thermoreceptors, and nociceptors are all examples of free endings, nociceptors are the most common type.

Detailed explanation-2: -Nerve Endings There are typically three encapsulated types of joint receptors. These resemble pacinian corpuscles, Ruffini endings, and Golgi tendon organs. There is also a nonencapsulated type of nerve ending that is thought to be a nociceptor specific for pain associated with movement.

Detailed explanation-3: -The dermis contains hair follicles, sweat glands, sebaceous (oil) glands, blood vessels, nerve endings, and a variety of touch receptors. Its primary function is to sustain and support the epidermis by diffusing nutrients to it and replacing the skin cells that are shed off the upper layer of the epidermis.
