No, they attach to the outside of the hair follicle.
still flows and carries debris to the end of the glacier
Xylem, It transports minerals and water from roots to shoots.
because they are dangerous and can kill people
The pilomotor response, also known as goosebumps or goose pimples, is a reflex in which hair follicles contract in response to cold temperatures or strong emotions, causing hairs to stand on end. This response is caused by the contraction of tiny muscles at the base of each hair follicle, which can help trap heat close to the skin or make animals appear larger in the face of a threat.
Piloerection, also known as "goosebumps," is a physiological response in which the small muscles at the base of hair follicles contract, causing the hairs to stand on end. This response is triggered by various stimuli such as cold temperature or emotional arousal. In animals, piloerection can make the individual appear larger to intimidate or ward off potential threats.
Piloerection, or goosebumps, is a physiological response where hair stands up on end. In response to cold temperatures, piloerection traps a layer of air near the skin to provide insulation and reduce heat loss. However, in response to heat, piloerection is not as effective in reducing heat loss.
The scientific term for goose bumps is piloerection. It refers to the contraction of the tiny muscles at the base of hair follicles, causing the hairs to stand on end. This response is triggered by cold temperatures or emotional stimuli, such as fear or excitement.
This phenomenon is caused by the piloerector muscles contracting, which can be triggered by fear, cold temperatures, or emotional responses. The muscles pull on the hair follicles, causing the hairs to stand upright. This is known as piloerection, or colloquially as "goosebumps."
Hair standing on end.
In cold weather, your body may trigger a process called piloerection, where the tiny muscles at the base of hair follicles contract, causing hair to stand on end. This response is a leftover evolutionary trait aimed at trapping heat close to the body. The hairs on your arms and legs may appear more prominent but do not actually generate warmth.
The erector pili muscle is a small muscle attached to hair follicles in mammalian skin. Its contraction causes hairs to stand on end, creating "goosebumps" or piloerection. This response is part of the body's fight or flight reaction to cold, fear, or other stimuli.
When cats' backs ripple, it is a sign of excitement or playfulness. This behavior is known as piloerection, where the muscles in the skin contract, causing the fur to stand on end. It is a natural response to heightened emotions in cats.
A cat's tail may become bushy as a sign of fear, excitement, or aggression. This reaction, known as piloerection, occurs when the muscles at the base of the hair follicles contract, causing the hair to stand on end and the tail to appear bushy.
Animals have hair to keep them warm in the wild. Also, with animals like cats and dogs, in a fight their hair stands on end, making them look bigger :)
Those are known as arrector pili muscles. They are responsible for contracting and causing hairs to stand up in response to cold or emotional stimuli.
If you are referencing to goosebumps those are actually little muscles that attach to your hair follicle that make it stand up. This process is in response to fear or coldness. In animals their hair stands up to thwart away predators. In humans, it doesn't do that but its the same muscle that pulls the follicle up.
