Understanding goosebumps: A basic biological phenomenon relevant for general science exams.
Summary
This article discusses the biological phenomenon of goosebumps, a common human physiological response. While no specific content was provided, the topic itself relates to basic human physiology, which is relevant for general science sections in competitive exams. Understanding such fundamental biological processes is crucial for a broad knowledge base.
Key Points
- 1Goosebumps, also known as piloerection or cutis anserina, is a physiological response in humans.
- 2It occurs due to the contraction of tiny arrector pili muscles attached to hair follicles.
- 3This muscle contraction causes the hair to stand erect, creating the characteristic bumps on the skin.
- 4Common triggers include cold temperatures, fear, strong emotions, awe, or even specific sounds.
- 5The pilomotor reflex is considered a vestigial response, inherited from ancestors, for insulation or to appear larger.
