Introduction:

The skin has three layers namely- epidermis, dermis, and subcutaneous layer. The dermis contains hair follicles, glandular cells, blood vessels, and connective tissues. The dermis layer provides elasticity to the skin and the sense of touch and pain by the presence of sensory receptors. The hair follicles have three layers where the outer layer is the cuticle, the middle is the cortex, and the innermost layer is medulla which is also known as the central core of the hair follicle.
