Explanation:

Identify the core question

The question asks to identify the two main parts of a hair from the given options. This relates to the anatomy of the Integumentary System.

Analyze the anatomical structures of hair

A hair is a filament of keratinized cells that grows from an oblique tube in the skin called the hair follicle. Anatomically, a single hair is divided into two primary parts based on its relationship to the skin surface:

1. Hair shaft: The portion of the hair that projects above the epidermis (visible on the surface of the skin).
2. Hair root: The portion of the hair embedded deep within the dermis, below the skin surface.

Evaluate the given options

• Hair root: This is one of the two main parts of the hair (the portion below the skin surface).
• Hair shaft: This is the other main part of the hair (the portion above the skin surface).
• Hair follicle: This is the pocket or tube-like depression in the skin that contains the hair root, but it is an accessory skin structure rather than a part of the hair itself.
• Epilation: This is a medical term referring to the removal of hair by the roots, not an anatomical part of the hair.

Select the correct options

Based on the anatomical division of a hair, the two parts are the Hair root and the Hair shaft.

Answer:

• Hair root (Correct answer)
• Hair shaft (Correct answer)
• Hair follicle
• Epilation
