Question
Chapter 5, Problem 16RQ
Summary Introduction
To determine:
The function of arrector pili muscles.
Introduction:
The skin is composed of the cutaneous membrane and accessory structures. In the accessory structures the hair and the hair follicles are of particular importance. The arrector pili muscles are the smooth muscle cells that surround the hair. They are activated by stimulation and cause the hair follicles to stand erect.
