The hair cycle

The relative duration of these different stages influences the length and appearance of hair in different parts of the body. The first stage is known as anagen during which active mitotic division occurring in the basal matrix of the hair follicle leads to hair growth.

Is hair cells mitosis or meiosis?

Somatic cells make up your body. Your hair, skin, bones, muscles, eyes and even your brain are made of somatic cells. These cells reproduce using mitosis so that each daughter cell is an exact clone.

What is the hair follicle made up of?

The hair follicle is made of multiple layers of cells that form from basal cells in the hair matrix and the hair root. Cells of the hair matrix divide and differentiate to form the layers of the hair.

How does mitosis affect hair growth?

Approximately 90% of hairs taken from a normal scalp are anagen hairs. This is a period of epithelial proliferation, in which bulb matrix cells undergo mitosis and proliferation to form the hair shaft. … Kenogen is the lag phase between loss of telogen hair and the growth of new hair.

Do hair cells divide?

Others want to know what makes a hair cell a hair cell, so they can find a way to make surrounding cells in the inner ear turn into hair cells. These cells do not normally divide, so once they are lost, the only hope is to somehow induce them to divide or to turn neighboring cells into hair cells.

Where are hair cells?

In mammals, the auditory hair cells are located within the spiral organ of Corti on the thin basilar membrane in the cochlea of the inner ear. They derive their name from the tufts of stereocilia called hair bundles that protrude from the apical surface of the cell into the fluid-filled cochlear duct.

What type of cell is a hair cell?

Hair Cells. Hair cells are the transducers that change mechanical energy of motion to electrical signals conveyed as vestibular nerve action potentials. These hair cells come in two shapes, a goblet-shaped type I cell and a thinner, more columnar type II cell (Fig. 8.4A).
