Structures of the Fingernail in a Lateral View

The fingernail is composed of several key structures, each serving a specific purpose. In a lateral view, these structures can be clearly identified and labeled. Below is a detailed description of each component:

The Key Structures

• Nail Matrix: The area under the base of the nail where new cells are produced, leading to nail growth.
• Nail Bed: The skin beneath the nail plate that supports the nail.
• Lunula: The visible part of the matrix, often seen as a white crescent shape at the base of the nail.
• Cuticle: The layer of clear skin located along the bottom edge of your finger or toe, protecting the matrix from infection.

Step-by-Step Labeling Guide

1. Identify the Nail Matrix: Locate the area beneath the cuticle where the nail grows.
2. Locate the Nail Bed: Observe the skin underneath the nail plate.
3. Find the Lunula: Look for the white crescent shape at the base of the nail.
4. Examine the Cuticle: Identify the thin layer of skin at the base of the nail.
