Question

STRUCTURED/APPLICATION/SKILL TYPE
Given below is a diagrammatic sketch of the vertical section of the human skin.
Name any one of the above parts which has at least three functions.

Answer 1

• The skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.
• The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.
• The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
• Accessory structures of the skin include hair, sweat glands, and sebaceous glands.
• Sebaceous glands secrete the oily, waxy substance called sebum that is made of triglycerides, wax esters, squalene, and metabolites of fat-producing cells. Sebum waterproofs and lubricates the skin and hair of mammals.
