MICROANATOMY

Detailed explanation-1: -The ends of the nails usually consist only of the “superficial", hardened layer and are not pointed like claws. With only a few exceptions, primates retain plesiomorphic (original, “primitive") hands with five digits, each equipped with either a nail or a claw.

Detailed explanation-2: -The nail bed is a specialized structure of the epidermis that is found at the tips of our fingers and toes. The nail body is formed on the nail bed, and protects the tips of our fingers and toes as they are the farthest extremities and the parts of the body that experience the maximum mechanical stress (Figure 1).
