Which muscles in the skin contract to make the hairs on our skin stand up straight (goosebumps) when we are cold or frightened?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. Arrector pili.

Arrector pili Muscle
  • It is a tiny muscle that attaches to the base of a hair follicle at one end and to dermal tissue on the other end.
  • To generate heat when the body is cold, the arrector pili muscles contract all at once, causing the hair to 'stand up straight' on the skin.
