What part of the nervous system stimulates the arrector pili muscles and give you goosebumps?
Each arrector pili is composed of a bundle of smooth muscle fibres which attach to several follicles (a follicular unit), and is innervated by the sympathetic branch of the autonomic nervous system. The contraction of the muscle is therefore involuntary - stresses such as cold, fear etc. may stimulate the sympathetic nervous system and thus cause contraction, but the muscle is not under conscious control.

What gland causes goose bumps?
Goosebumps are caused by the contraction of tiny muscles at the base of hair follicles, known as arrector pili muscles. This reaction is typically triggered by the autonomic nervous system in response to cold temperatures or emotional stimuli, rather than a specific gland. While sweat glands can play a role in the body's response to temperature, it is the muscles, not glands, that create the appearance of goosebumps.
What body system stimulates muscles to contract and interprets information from sensory organs?
The nervous system which also interprets information from sensory units
What 3 structures are only innervated by the sympathetic nervous system?
The structures that are only innervated by the sympathetic nervous system include the sweat glands, arrector pili muscles (responsible for piloerection or goosebumps), and the adrenal medulla (part of the adrenal gland that releases hormones like adrenaline).
What is the System that relays commands to skeletal muscles and stimulates glands and other muscle so that the organism may continue to live and respond to stimuli?
nervous
What organs have only sympathetic innervation?
The adrenal medulla and the arrector pili muscles are examples of organs that receive only sympathetic innervation. The adrenal medulla functions as an endocrine organ, releasing hormones like adrenaline during the "fight or flight" response. The arrector pili muscles, which cause hair to stand on end, are also solely controlled by the sympathetic nervous system.
What kind of muscle is the arrector pili?
The contraction or relaxation of the erector pili muscle determines the orientation of hair on the skin. When it contracts, due to fear or cold, hair stands upright.This is a tiny muscle that attaches to the base of a hair follicle mammals at one end and to dermal tissue on the other end.
Does the arector pili muscles receive direct parasympathetic innervation?
Arector pili muscles get innervation from sympathetic out flow. But the neurotransmitter is acetylcholine. So functionally the nerve supply is parasympathetic.
Causes hair to stand on end?
Little muscles at the base of each hair shaft called arrector pili (also Erector pili).When we are cold, muscles just below our skin, called erector muscles, contract. This pulls on our hairs, causing them to stand on end. By doing this, the hairs form an insulating layer of air, which keeps us warm and maintans our constant internal body temperature.
What is a somatic nervous system?
A nerve that is under your conscious control and stimulates skeletal muscles also controls voluntary movements, such as writing, talking, smiling or jumping
What system gives you goosebumps?
the un (unvlountary) nervous system gives you goosesbumps.
What stands hairs on end causing piloerection?
Piloerection, or the standing of hairs on end, is primarily caused by the contraction of tiny muscles called arrector pili located at the base of hair follicles. This reaction is typically triggered by cold temperatures, which help to trap heat, or by strong emotions such as fear or excitement, which can activate the body's fight-or-flight response. The sympathetic nervous system stimulates these muscles, causing the hairs to stand upright. This reflex is a vestigial response inherited from our animal ancestors, where it would make them appear larger to predators or to retain warmth.
