Where do the cells divide to produce hair?
Hair cells divide in the hair follicle, which is located in the outer layer of the skin called the epidermis. The hair follicle contains stem cells that divide and differentiate to produce new hair cells, eventually forming the hair shaft that grows out of the skin.
What part of the hair shaft is made of cortical cells?
The cortex layer of the hair shaft is made of cortical cells. It is the middle layer of the hair shaft and provides strength, elasticity, and color to the hair.
Hair is produced by cells called?
I believe it is produce by scalpition but I am not sure if that is the right answer if any one has a better answer put it down. Hair is composed of keratinized dead cells that have been pushed to the surface.
Where does hair production occur?
Hair production occurs in hair follicles, which are tiny pockets in the skin where hair begins to grow. The hair follicle contains cells that divide and grow to produce the hair shaft that we see on the surface of the skin.
What are cuticle scales?
Cuticle scales are formed from dead cells on the hair cuticle, which is the outer layer of the hair shaft. The scales give the hair shaft strength.
What gland is connected to the hair follicle?
Sebaceous glands are associated with hair follicles. They produce oil that lubricate the hair shaft.
Does the hair bulb produce hair?
Only the cells of the hair bulb are alive to understand this more here is how the hair bulb if formed. Hair follicles forms a cluster of cells in the upper layer of the skin. These cluster of cells are called the primitive hair germ, which needs nourishment to grow into a developed hair follicle. To get nourishment it works all the way down into the lower layer of the skin. As it does, the cell cluster pulls the upper layer down with it creating a follicle called the root Sheath, out of which the hair will grow. The shape of this follicle then determines the shape of the hair shaft as it grows from the follicle.
What part of the hair extends from the hair papilla to the body surface?
The hair shaft extends from the hair papilla to the body surface. It is made up of keratinized cells that form the visible part of the hair.
What are tube like pockets of epidermal cells that extend into the dermis?
Hair follicles are tube-like structures that extend from the epidermis into the dermis. They are comprised of epidermal cells and contain the hair shaft.
Why does hair absorb oil?
Hair is made of proteins, mostly keratin. The cells are no longer vascular, but the outside of the hair shaft is porous, and can absorb water and oil.
A portion of the hair where mitosis takes place?
The portion of hair where mitosis occurs is the hair bulb, which is located at the base of the hair follicle. This is where new hair cells are produced, and as they multiply and differentiate, they push older cells up the follicle, forming the hair shaft.
What is the outer layer of the hair shaft called?
The outer layer of the hair shaft is called the cuticle. It consists of overlapping layers of thin cells that help protect the hair strand and give it its strength and flexibility.
