<p><b>New page</b></p><div>'''Hair plexus''' is a term used in [[anatomy]] to describe a network of [[nerve]] fibers that surround the base of each [[hair follicle]]. This network of nerves allows for the sensation of hair movement, contributing to the sense of [[touch]].<br />
<br />
==Structure==<br />
The hair plexus is formed by the wrapping of [[sensory nerve]] fibers around the base of each hair follicle. These nerve fibers are a type of [[free nerve ending]], and they are highly sensitive to the movement of the hair. When the hair moves, these nerve endings generate an [[electrical signal]] that is transmitted to the [[brain]], allowing the individual to perceive the sensation of touch.<br />
<br />
==Function==<br />
The primary function of the hair plexus is to detect the movement of hair. This is an important aspect of the sense of touch, as it allows individuals to detect the presence of small insects or other objects on the skin. The hair plexus also plays a role in the [[goosebump]] response, as the contraction of the [[arrector pili muscle]] in response to cold or fear can stimulate the nerve endings in the hair plexus.<br />
<br />
==Clinical significance==<br />
Damage to the hair plexus can result in a loss of sensation in the affected area. This can occur as a result of [[nerve injury]], [[skin disease]], or certain [[neurological disorders]]. In some cases, the hair plexus may be affected by [[neuropathy]], a condition that causes damage to the peripheral nerves.<br />
