The formation of goose bumps in humans under stress is considered by some to be a vestigial reflex, [4] though visible piloerection is associated with changes in skin temperature in humans. [5] The reflex of producing goose bumps is known as piloerection or the pilomotor reflex , or, more traditionally, [ 6 ] horripilation .
Keratosis pilaris (KP; also follicular keratosis, lichen pilaris, or colloquially chicken skin. [1]) is a common, autosomal-dominant, genetic condition of the skin's hair follicles characterized by the appearance of possibly itchy, small, gooseflesh-like bumps, with varying degrees of reddening or inflammation.

Frisson (UK: / ˈ f r iː s ɒ n / FREE-son, US: / f r iː ˈ s oʊ n / free-SOHN [1] [2] French:; French for "shiver"), also known as aesthetic chills or psychogenic shivers, is a psychophysiological response to rewarding stimuli (including music, films, stories, people, photos, and rituals [3]) that often induces a pleasurable or ...
They got their name because they look like the skin of a plucked bird. Goosebumps have a practical purpose for animals. When an animals’ hair sticks up it makes it look bigger and helps protect ...
Skin conditions such as leprosy can damage arrector pili muscles, preventing their contraction. [9] Inducing contraction of the arrector pili muscles via an α1-adrenergic receptor agonist has been shown to reduce hair shedding as a result of traction alopecia [ 10 ]
The formation of goose bumps in humans under stress is a vestigial reflex; [31] its function in human ancestors was to raise the body's hair, making the ancestor appear larger and scaring off predators. The arrector pili (muscle that connects the hair follicle to connective tissue) contracts and creates goosebumps on skin. [32]
