Piloerector Muscle
The arrector pili muscle is responsible for causing hair to stand on end when contracted. It is a small bundle of smooth muscle fibers attached to the hair follicle. When this muscle contracts, it pulls on the hair follicle, making the hair upright.
The muscle responsible for the goosebumps appearance is the arrector pili muscle. When stimulated, this muscle contracts and pulls on hair follicles, causing them to stand upright and creating the appearance of goosebumps on the skin.
The arrector pili muscles makes the hairs on your arm stand on end.
The pilosebaceous unit consists of a hair follicle, sebaceous gland, and associated arrector pili muscle. The hair follicle produces hair, the sebaceous gland secretes oil to lubricate the skin and hair, and the arrector pili muscle is responsible for causing hair to stand up on end.

Arrector Pili Muscle
The root of each hair follicle is connected to the small arrector pili muscles are small muscles attached to hair follicles in mammals. Each arrector pili muscle has a bundle of smooth muscle fibers which attach to the follicular units which have nerves.
tiny muscle fibers attached to each hair follicle, which contract to make the hairs stand on end, causing goose bumps.
The arrector pili muscle is the structure responsible for pulling on the hair follicle, causing it to stand up and creating goosebumps. This muscle contracts in response to cold or emotional stimuli, causing the hairs to elevate and creating the appearance of goosebumps on the skin.
Standing hair is caused by the tiny muscle that connects the hair to the follicle. This muscle is called the arrector pili.
