Low kick sciatic nerve, which is the longest and widest nerve in the human body, beginning in the lower back and running through the buttocks all the way to the lower limb, is a frequent target for low kicks. The most common defense against a low kick is known as "checking", where the leg is bent and brought up to protect the thigh. This causes the kicker to slam their shin into the defending fighters' shin or knee, causing pain and damage to the offender. In some instances, a well executed check of a low kick can break the leg of the
Nerve supply to the skin the most densely innervated parts of the body. Though there is no specific categorization, both “free” nerve endings and unencapsulated nerve endings of myelinated axons are found within the dermis of those areas. The cornea, one of the other exposed mucous membranes, contains “free” nerve endings served by nonmyelinated axons. The conjunctiva contains a less dense distribution of “free” nerve endings that are served by both myelinated and unmyelinated axons. The distribution of the sensory neurons within the skin accounts for the large and overlapping receptive fields of the skin. The size of the receptive fields in turn explains why
