Question

Quizplus · Accepted Answer

The medulla is the innermost layer of the hair shaft and is present in most, but not all, hairs. The cortex surrounds the medulla and is responsible for the hair's strength, elasticity, and color. The cuticle is the outermost layer of the hair shaft, while the glassy membrane, hair bulb, and connective tissue sheath are all structures associated with the hair follicle.
