MICROANATOMY

Detailed explanation-1: -The arrector pili muscle is a tiny muscle connected to each hair follicle and the skin. When it contracts it causes the hair to stand erect, and a “goosebump” forms on the skin. The hair follicle is a tube-shaped sheath that surrounds the part of the hair that is under the skin and nourishes the hair.

Detailed explanation-2: -Arrector pili muscles are composed of smooth muscle tissue, which means that the contractions of this muscle are involuntary. They are triggered to contract when the body experiences fear, and also when the body is cold. The contraction of these muscles produce “goosebumps.” The answer is false.

Detailed explanation-3: -The arrector pili muscle mass are small muscle mass attached to hair follicles in mammals. Contraction of those muscular tissues causes the hairs to face on end-regarded colloquially as goosebumps.
