FREE NERVE ENDINGS ANATOMY

Free nerve endings are considered rather simple. They are the least modified and are considered to be the most superficial of all the sensory receptors that deal in tactile sensation.

These simple receptors are driven into the lower layers of the epidermis and end in a knobby fashion jammed in between the various epithelial cells.

While free nerve endings can discern pressure, like the feel of a shoe around the foot, they are most useful for their main purpose, which is discerning sensations of pain and temperature.

A few of the free nerve endings are similarly sensitive to tickles and itches.
