Melanocytes: morphological basis for an exteroceptive sensory system for monitoring ultraviolet radiation.

From the conventional medical perspective, melanocytes have been traditionally viewed as epidermal responders/reactors to ultraviolet radiation. In this paper we have begun an analysis of the functional significance of melanocytes as monitors for ultraviolet radiation with their neuronal, endocrinological and immunological intercalations. This preliminary study was performed using as a human model unilateral sural nerve sensory blockade before and after ultraviolet exposure to both feet while the unblocked foot acted as the control.
