Question

Nerves at the roots of hair follicles to detect pain, temperature, itch, and hair movement are called _____.

Answer 1

Free nerve endings is the correct answer.

Step-by-step explanation:

Nerves at the roots of hair follicles to detect pain, temperature, itch, and hair movement are called Free nerve endings.

free nerve endings are the receptors that are present in the dermis region around the bottom of hair follicles and near to the skin surface.

Free nerve endings work as thermoreceptors(to detect temperature, heat) mechanoreceptors(to detect pressure) nociceptors( to sense pain)and they do not have complex sensory structures.

Hair receptors are quickly adapting free nerve endings encased around the bottom of the hair follicles that identify the pain, temperature, itch, and hair movement.

Answer 2

Answer: The correct answer for the blank is-

Free nerve endings.

Free nerve endings can sense temperature, various mechanical stimuli such as pressure, touch, stretch as well as pain and itch.

Free nerve endings extend from the dermis region to the spaces that are present between the epidermal cells. Their primary role is to detect pain ( that is nociception) but also serve other functions..

In other words, different free nerve endings act as thermoreceptors ( for sensing temperature/ heat), mechanoreceptors and ( for sensing pressure, touch, stretch) and nociceptors ( for sensing pain).
