Question

question 8 of 100
what is the function of the hair bulb?
select the correct response:
it contains cells that form the hair strand.
it causes goose bumps.
it anchors the hair in the skin.
it lubricates the hair and skin.

Explanation:

• Goose bumps are caused by arrector pili muscles, not the hair bulb.
• The hair follicle (not the bulb specifically) anchors hair, while the bulb's core role is housing matrix cells that divide to produce the hair strand.
• Lubrication is done by sebaceous glands, not the hair bulb.

Answer:

A. It contains cells that form the hair strand.
