Melanocytes & Skin Color<br />
• The melanin pigmentary system is<br />
composed of functional units -<br />
epidermal melanin units<br />
• Each unit consists of a<br />
melanocyte that supplies<br />
melanin pigment to a group of<br />
keratinocytes (about 36)<br />
• Pigmentation is determined primarily by<br />
the amount of melanin transferred to the<br />
keratinocytes
