3–58 Label the structures of the fingernail in Figure 3–3 as you read the following

material. Each nail is formed in the (1) nail rootand is composed of keratin, a hard

fibrous protein, which is also the main component of hair. As the nail grows from a

(2) matrixof active cells beneath the (3) cuticle,it stays attached and slides forward

over the epithelial layer called the (4) nail bed. Most of the (5) nail bodyappears

pink because of the underlying blood vessels. The (6) lunulais the crescent-shaped

area at the base of the nail. It has a whitish appearance because the vascular tissue

underneath does not show through.

Here is a review of the three basic rules of word building:

• Rule 1:Word root links a suffix that begins with a vowel.


• Rule 2:Combining form (root + o) links a suffix that begins with a consonant.


• Rule 3:Combining form (root + o) links a root to another root to form a compound word. (This rule holds
  true even if the next root begins with a vowel.)
