Final answer:
False, the cuticle of the hair does not directly influence hair texture or cause hairs to move; it serves as a protective outer layer.
Step-by-step explanation:
The cuticle of the hair is not directly responsible for the texture or movement of hair. The cuticle is the outermost layer of very hard, keratinized cells that protect the inner structures of the hair shaft. The hair texture, whether straight or curly, is determined by the shape and structure of the cortex and, to an extent, the medulla. These are influenced by the shape of the hair follicle, not by the cuticle itself.
While the cuticle does play a protective role and is involved in preventing damage to the hair, its function does not extend to controlling hair movement. Hair movement is actually detected by the hair follicle plexus, which consists of nerve endings that sense when the hair is moved. However, this does not imply that the cuticle itself causes the hair to move.
