Question

State any two functions of the mammalian skin other than those concerned with heat regulation.

Answer 1

Hint: Mammalian skin is made up of two layers: a nonvascular epidermis on the outside and a dermis, or corium, on the inside. Fingerlike projections (dermal papillae) of sensitive vascular dermis protruding into the epidermis connect the two layers. Skin aids in the control of body temperature and contributes to homeostasis. Other than thermoregulation, the skin also serves various other functions.

Complete answer:
The epidermis, dermis, and hypodermis are the three layers of the skin. The hypodermis, or subcutaneous fatty tissue, lies under the dermis.
Other than thermoregulation skin serves several important functions:
Protection The skin protects the body in a variety of ways. Sun protection, physical harm, and bacterial invasion are more specific examples.
Immunity: To combat bacteria and other pathogens, some skin cells collaborate with the immune system.
Water Resistance: The skin acts as a water-repellent barrier.
Endocrine: This important vitamin is produced when an organic molecule in your skin combines with sunlight.
Sensitivity: Skin can be extremely sensitive, allowing it to detect even minor changes in temperature and pressure.

Note:
A surface epidermis and a deeper dermis make up the skin's two primary layers. There are numerous layers to the epidermis. The top layer is made up of dead cells that shed on a regular basis, and it is gradually replaced by cells generated from the bottom layer. Because collagen and elastin fibres are present, the dermis links the epidermis to the hypodermis and gives strength and elasticity.
