The cortex provides pigment and strength. Which option best reflects this role?

• A. Blood supply
• B. Pigment and strength
• C. Glandular tissue
• D. Surface lubrication

Answer: (B)

Think about hair structure: the cortex is the thick, middle layer of the hair shaft that contains pigment granules and a dense keratin framework. The pigment granules give hair its color, and the keratin network provides the hair’s strength and resilience. So, describing the cortex as having pigment and strength fits its role exactly.

The other options don’t describe what the cortex does. Blood supply comes from vessels in the surrounding follicle and dermis, not from the cortex itself. Glandular tissue refers to sebaceous glands associated with hair but not part of the cortex. Surface lubrication comes from sebum on the skin and hair surface, not from the cortex.
