ANATOMY

Detailed explanation-1: -Understanding the skin requires knowledge of its accessory structures. These originate embryologically from the epidermis and include hair, nails, sweat glands and sebaceous glands. All are important in the skin’s key functions, including protection, thermoregulation and its sensory roles.

Detailed explanation-2: -Accessory structures of the skin include hair, nails, sweat glands, and sebaceous glands.

Detailed explanation-3: -Insulation: The hypodermis insulates your body to protect you from the cold and produces sweat to regulate your body temperature, protecting you from the heat. Protecting your body: The hypodermis allows your skin to move smoothly over the tissues and muscles underneath it.

Detailed explanation-4: -Eccrine sweat glands Eccrine glands are often referred to as the small gland variety, but are by far the most ubiquitous type of sweat gland [12]. Humans have  2–4 million eccrine sweat glands in total and are found on both glabrous (palms, soles) and non-glabrous (hairy) skin [13–15].
