Explanation:

Question 40

To solve this, we recall nail anatomy. The nail plate is the visible part of the nail that grows and slides over the nail bed. Nail grooves are the folds of skin, mantle is the tissue around the nail, and cuticle is the dead skin at the base. So the correct option is d.

Trichoptilosis is the technical term for split ends. Beaded hair is monilethrix, hair loss has other terms, and knotted hair is trichonodosis. So the correct option is b.

In nail anatomy, the free edge is the part of the nail plate that extends beyond the fingertip or toe tip. Nail body is the main visible part, cuticle area is around the base, and extension is not the correct term here. So the correct option is c.

Answer:

d. nail plate
