Which layer of the hair shaft gives hair most of its strength, elasticity and natural color?

Choose the best answer

What the anatomy questions test

  • The hair shaft has three layers: the cuticle (protective scales), the cortex (strength, elasticity and natural color) and the medulla (core). The dermal papilla nourishes the growing hair.
  • Hair grows about half an inch a month through anagen (growth), catagen (transition) and telogen (rest) phases.
  • Hydrogen bonds break with water or heat and re-form as hair dries or cools. Disulfide bonds break only with chemicals such as perm solutions and relaxers.
  • The skin has the epidermis (outer, no blood vessels; new cells form in the stratum germinativum) and the dermis (blood vessels, nerves, sebaceous and sudoriferous glands).
  • Cranium bones: occipital, two parietal, frontal, two temporal, ethmoid and sphenoid. The mandible is the lower jaw and the zygomatic bones form the cheeks.
  • The masseter and temporalis chew, the orbicularis oris closes the lips, the platysma lowers the jaw, and the sternocleidomastoideus turns and bends the head.
  • The fifth cranial (trifacial) nerve is the chief sensory nerve of the face; the seventh (facial) nerve is its chief motor nerve.

Common questions

Which layer of the hair gives it color?

The cortex. It holds the melanin and the keratin fibers that give hair its strength and elasticity.

What are the three stages of hair growth?

Anagen, the active growth phase; catagen, a short transition; and telogen, the resting phase before the hair sheds.
