Question

Caused by cold, fever, or sudden excitement, our muscles near the hair roots on our bodies pull the muscle tight. What is this called? a) Goosebumps b) Shivering c) Muscle contraction d) Sweating

Answer 1

Goosebumps occur when the arrector pili, the muscles near the hair roots, contract in response to stimuli like cold, fever, or sudden excitement. This causes the hairs to stand on end, which we refer to as 'goosebumps'.

Step-by-step explanation:

The sensation you're asking about is called Goosebumps, and it happens when the muscles near the hair roots, specifically the arrector pili, contract in response to stimuli like cold, fever, or sudden excitement. The arrector pili are small muscles attached to hair follicles in mammals. When these muscles contract, they cause the hairs to stand on end, creating what we commonly refer to as goosebumps. This is a natural response often associated with the body's reaction to intense emotions, cold or shock.
