Explanation:
Detailed explanation-1: -Goosebumps occur when tiny muscles in our skin’s hair follicles, called arrector pili muscles, pull hair upright. For animals with thick fur, this response helps keep them warm.
Detailed explanation-2: -The contraction of arrector muscles pulls the hair to vertical position at one end and depresses the epidermis at the other end. Arrector muscles runs obliquely between the hair follicle and the outer part of the dermis.
Detailed explanation-3: -Other medical terms for goosebumps are horripilation, piloerection, or the pilomotor reflex. Each of these terms describes a temporary change in the skin from smooth to bumpy, most commonly developing after exposure to cold.
