What is the primary function of melanocytes in the integumentary system?
A
To secrete sebum, which lubricates the skin
B
To produce keratin, which strengthens the skin
C
To produce melanin, which protects against UV radiation
D
To form the outermost layer of the epidermis
Verified step by step guidance1
Identify the role of melanocytes in the integumentary system. Melanocytes are specialized cells located in the basal layer of the epidermis.
Understand the primary function of melanocytes, which is to produce melanin, a pigment responsible for skin color.
Recognize that melanin plays a crucial role in protecting the skin from ultraviolet (UV) radiation by absorbing and dissipating the harmful rays.
Differentiate the function of melanocytes from other cells in the skin, such as sebaceous glands that secrete sebum and keratinocytes that produce keratin.
Conclude that the primary function of melanocytes is to produce melanin, which provides protection against UV radiation, rather than secreting sebum or producing keratin.
