GENERAL HISTOLOGY

Detailed explanation-1: -When you are burned, you experience pain because the heat has destroyed skin cells. Minor burns heal much the same way cuts do. Often a blister forms, which covers the injured area. Under it, white blood cells arrive to attack the bacteria and a new layer of skin grows in from the edges of the burn.

Detailed explanation-2: -Sensation can be divided into four types: superficial, deep, visceral, and special. Superficial sensation is concerned with touch, pain, temperature, and two-point discrimination. Deep sensation includes muscle and joint position sense (proprioception), deep muscle pain, and vibration sense.

Detailed explanation-3: -Broadly, these sensations can classify into two categories. General sensations which include touch, pain, temperature, proprioception, and pressure. Special Senses: Vision, hearing, taste, and smell which convey sensations to the brain through cranial nerves.

Detailed explanation-4: -For the ability to sense a sharp object, the best screening test uses a safety pin or other sharp object to lightly prick the face, torso, and 4 limbs; the patient is asked whether the pinprick feels the same on both sides and whether the sensation is dull or sharp.
