AP PSYCHOLOGY

Detailed explanation-1: -Melanocytes, found in the deep basal layer of the epidermis, contain brown granules called melanin. Besides contributing to skin color, melanin provides protection during episodes of sun exposure. Carotene found in subcutaneous fat tissue contributes to the yellowish color of the skin.

Detailed explanation-2: -Melanin is predominantly restricted to the basal layer (or Stratum basale) of the human epidermis, where it is found in both melanocytes (MCs), the cells that make melanin, and in nearby keratinocytes (KCs), the cells of the epidermis that accept melanin.

Detailed explanation-3: -Melanocytes produce the skin coloring or pigment known as melanin, which gives skin its tan or brown color and helps protect the deeper layers of the skin from the harmful effects of the sun.

Detailed explanation-4: -The epidermal melanin unit (EMU) denotes the symbiotic relationship between a melanocyte and a pool of associated keratinocytes.

Detailed explanation-5: -Melanin helps protect the cells of the epidermis, or outer layer of the skin, from UV light. This protection extends to all forms of UV light (UVC, UVB, and UVA) as well as blue light. It does this by absorbing the UV light before it’s able to damage the sensitive DNA of the skin cells.
