Definition of skin effect. : an effect characteristic of current distribution in a conductor at high frequencies by virtue of which the current is greater near the surface of the conductor than in its interior resulting in an increase of resistance with increasing frequency.
Functions of skin. Protection: it protects against UV light, mechanical, thermal and chemical stresses, dehydration and invasion by micro-organisms. Sensation: skin has receptors that sense touch, pressure, pain and temperature. Thermoregulation: various features of the skin are involved in regulating temperature of the body. For example sweat glands, hair, and adipose tissue. Metabolic functions: subcutaneous adipose tissue is involved in production of vitamin D, and triglycerides. This diagram shows the layers found in skin. There are three main layers: the epidermis, dermis and hypodermis. There are also sweat glands, and hairs, which have sebaceous glands, and a smooth muscle called the arrector pili muscle, associated with them.
