Which type of nerves are connected to the muscles that cause goosebumps?

1. Sensory Fiber Nerves

2. Motor Fiber Nerves

3. Sympathetic Nerves

4. Parasympathetic Nerves

The correct answer is: Motor Fiber Nerves

The nerves responsible for causing goosebumps are motor fiber nerves, which play a crucial role in the innervation of muscles. When the body experiences cold temperatures or emotional stimuli such as fear or excitement, the small muscles at the base of hair follicles, called arrector pili muscles, contract. This contraction leads to the elevation of hair and the formation of goosebumps. Motor fiber nerves specifically transmit signals from the central nervous system to these muscles, initiating their contraction. While sympathetic nerves are involved in the autonomic responses to stimuli that can also lead to goosebumps, the direct action causing the muscles to contract is through motor fibers. Therefore, motor fiber nerves are the correct choice, as they specifically govern the movement of the muscles involved in the phenomenon of goosebumps.
