Question

multiple choice question
what is the function of a hair receptor?

○ sense acid level in the acid mantle

○ detect heavy pressure

○ detect movement of the hair

○ detect variations in temperature

Explanation:

Hair receptors, also called hair follicle receptors, are sensory structures associated with hair follicles. They are mechanoreceptors that respond to the displacement or movement of the hair shaft caused by light touch or air movement. The other options are incorrect: acid level sensing is not their role, heavy pressure is detected by deep pressure receptors like Pacinian corpuscles, and temperature is detected by thermoreceptors.

Answer:

detect movement of the hair
