It (oxygen) enters the lungs, is absorbed by the alveoli in the walls of the lungs, transferred in red blood cells to the heart, where it is pumped into the aorta, then to the arteries and veins and then the capilaries that feed the hair follicles which reside above the temporalis muscle.
arrector pili.
arector pili muscle
The muscle connected to hair follicles is called the arrector pili muscle. This small, smooth muscle contracts in response to cold or emotional stimuli, causing the hair to stand erect, a phenomenon commonly known as "goosebumps." These muscles play a role in thermoregulation and can also make the animal appear larger to potential threats.
The arrector pili muscles are in the hair follicles. When contracted, they cause the hair to stand on ends, commonly known as goosebumps.
tiny muscle fibers attached to each hair follicle, which contract to make the hairs stand on end, causing goose bumps.
Hair is attached to the head by hair follicles, which are tiny pockets in the skin where hair grows from. Each hair follicle is connected to a sebaceous gland and a tiny muscle called the arrector pili muscle, which help with hair growth and positioning. Blood vessels in the scalp also play a role in nourishing the hair follicles.
Blood vessels in the scalp provide nutrients and oxygen to hair follicles, enabling them to grow. As long as the blood vessels are healthy and continue to supply the required nutrients, the blood stream will feed the hair follicles, supporting their growth. If there are any issues with blood flow or nutrient supply, it can affect the health and growth of the hair follicles.
How long does alochol stay in hair follicles
No, the dermis gives rise to hair follicles.
The arrector pili muscle is a small smooth muscle attached to hair follicles in the skin. When it contracts, usually in response to cold or emotional stimuli, it causes the hair to stand upright, a phenomenon known as piloerection or "goosebumps." This reaction can help insulate the body by trapping air or making the animal appear larger to predators. Additionally, it plays a role in the secretion of sebum from sebaceous glands associated with hair follicles.
Hair follicles are embedded in the dermis layer of the skin.
The muscle responsible for the goosebumps appearance is the arrector pili muscle. When stimulated, this muscle contracts and pulls on hair follicles, causing them to stand upright and creating the appearance of goosebumps on the skin.
