Question

Quizplus · Accepted Answer

The root hair plexus is a network of sensory nerves that surrounds the base of each hair follicle. It is responsible for detecting movement of the hair, from a single hair being moved to a light breeze blowing across a large number of hairs. The other options, while important in hair function, do not specifically respond to hair movement at this level of sensitivity.
