How Do You Spell PILOMOTOR REFLEX?

Pronunciation: [pˈa͡ɪləmˌə͡ʊtə ɹˈiːflɛks] (IPA)

The Pilomotor Reflex is a physiological response to stress or excitement that causes muscles at the base of hair follicles to contract, resulting in the hair standing on end. The spelling of "Pilomotor" is pronounced /ˌpaɪ.loʊˈmoʊ.tər/ in IPA phonetic transcription. The word is derived from two roots: "pilo," which means "hair," and "motor," which refers to the muscles involved in the reflex. The spelling accurately represents the word's pronunciation and highlights its meaning, which is related to hair and muscles.

PILOMOTOR REFLEX Meaning and Definition

1. The Pilomotor Reflex, also known as the piloerection reflex or the goosebumps response, is a involuntary bodily reaction characterized by the erection of hairs on the skin due to various stimuli. This reflex is commonly observed in mammals, including humans, and is primarily associated with the contraction of tiny muscles known as arrector pili muscles that are attached to the hair follicles.

   When an individual experiences certain stimuli, such as exposure to cold temperatures, fear, excitement, or strong emotions, the autonomic nervous system is activated, leading to the activation of pilomotor reflex. The sympathetic nervous system, specifically, is responsible for triggering this reflex. As a result, the arrector pili muscles contract, causing the hair follicles to become more upright and pulling the hair strands perpendicular to the skin surface.

   As the hair raises on the skin, the skin appears bumpy, often resembling the skin of a plucked bird or chicken, hence the popular term "goosebumps." The purpose of this reflex in humans is believed to be a vestigial trait originating from our evolutionary ancestors. It served as a defense mechanism to make early mammals appear larger and more intimidating to potential threats or to create a layer of insulation against the cold.

   In summary, the pilomotor reflex is an automatic reaction triggered by various stimuli that results in the erection of hair on the skin's surface. It is a survival mechanism that assists in thermal regulation, protection, and possibly social signaling.

Etymology of PILOMOTOR REFLEX

The word "Pilomotor" originates from two components: "pilo" and "motor", each with their own etymology.

The prefix "pilo-" is derived from the Greek word "pilós", meaning "hair". It is often used in medical terminology to refer to hair-related terms.

The suffix "-motor" comes from the Latin word "mōtor", meaning "one who moves". It is typically used to describe mechanisms or processes related to movement in scientific terminology.

Thus, the term "Pilomotor" combines these components to refer to the movement or action related to hair. In the context of the "Pilomotor Reflex", it specifically refers to the contraction of the muscles around hair follicles, which causes hair to stand upright (commonly known as "goosebumps" or "piloerection").
