MICROANATOMY

Detailed explanation-1: -The dermis contains nerve endings, sweat glands and oil glands (sebaceous glands), hair follicles, and blood vessels. The nerve endings sense pain, touch, pressure, and temperature.

Detailed explanation-2: -Sensory nerve endings in the skin can elicit all of the principal sensations: touch, pain, itch, warmth, and cold. The skin is supplied by both myelinated and unmyelinated branches of spinal nerves. Nerve branches enter the dermis from the subcutaneous fat and form both a superficial and a deep nerve plexus.

Detailed explanation-3: -Every square inch of skin contains 20 feet of blood vessels, 100 oil glands and 650 sweat glands. It also contains more than 1, 000 nerve endings that sense touch, pain, temperature and pressure.

Detailed explanation-4: -The second layer (located under the epidermis) is called the dermis; it contains nerve endings, sweat glands, oil glands, and hair follicles.
