The muscle connected to the hair follicle is called the:

1. epicranius

2. arrector pili

3. procerus

4. auricularis

The correct answer is: arrector pili

The muscle connected to the hair follicle is known as the arrector pili. This muscle is responsible for causing your hair to stand on end, resulting in "goosebumps" or "chicken skin" when you're cold or experiencing strong emotions. The other options are incorrect because they are not directly connected to the hair follicle. The epicranius is a muscle of facial expression that raises the eyebrows and wrinkles the forehead. The procerus is also a facial muscle, responsible for pulling down the eyebrows and causing vertical wrinkles between the eyebrows. The auricularis muscles are located around the ear and are responsible for moving the ears. However, none of these muscles have a direct connection to the hair follicle like the arrector pili does.
