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.
Is growing hair a chemical or physical change?
Growing hair is a biological process that involves physical changes. Cells in hair follicles divide and differentiate to produce new cells, which then form hair strands. This process does not involve a chemical reaction that alters the chemical composition of the hair.
What Inside the cochlea contains hearing receptor cells?
The cochlea contains hearing receptor cells called hair cells. These cells convert sound vibrations into electrical signals that are sent to the brain via the auditory nerve for processing.
What structure contains hair cells receptive to changes in dynamic equilibrium?
The structure that contains hair cells receptive to changes in dynamic equilibrium is the semicircular canals in the inner ear. These canals are responsible for detecting rotational movements and maintaining balance.
How many cells are contained in each trichome?
A typical trichome contains multiple cells arranged in a specific structure depending on the plant species. The number of cells can vary, but trichomes commonly consist of one to several dozen cells.
Is hair nonliving or living?
Hair is considered nonliving because it is composed of dead cells that are no longer actively growing or metabolizing. Although hair follicles are living structures that produce hair, once the hair emerges from the follicle, it is no longer alive.
Why do babies have no hair when their born?
because their hair cells are forming and growing
Receptors that contains hair bundles hair cells and supporting cells?
spiral organ of Corti
Can chemotherapy help thicken blood?
Chemotherapy destroys actively growing cells such as hair, lining of stomach, and blood cells...because cancer is a tumor of fast growing cells. this is why people on chemotherapy get nausea and vomiting, and hair loss and become anemic. there are products that can be taken to increase RBC production, erythropoetin. This is what athletes use to increase their RBCs and therefore oxygen carrying capacity Therefore your blood doesn't get "thicker", you lose red blood cells, white blood cells, platelets etc. with chemotherapy.
The epidermis contains what?
The epidermis contains several layers of cells, including keratinocytes, melanocytes, Langerhans cells, and Merkel cells. It also contains nerve endings, blood vessels, and hair follicles.
Is growing hair a chemical or physical change?
Growing hair is a biological process that involves physical changes. Cells in hair follicles divide and differentiate to produce new cells, which then form hair strands. This process does not involve a chemical reaction that alters the chemical composition of the hair.
Why does your hair gray when you get older?
Each hair follicle contains a certain number of pigment cells. As we age the pigment cells in the hair follicles gradually die and the hair turns gray, silver, or white.
How are scale-like parts of the hair are formed?
The scale-like parts of the hair, known as cuticles, are formed by overlapping layers of cells that are flat and thin. These cells provide protection for the inner layers of the hair shaft and help to maintain the hair's structure and strength. The direction in which these cuticle cells lay can impact the hair's overall appearance and texture.
How does chemotherapeutic drugs kill the cancer cells and not kill the human?
Basically, chemo drugs target the fastest-growing cells. So they kill cancer cells, but also some fast-growing human cells like those in hair follicles and the gastrointestinal tract (that's why chemo patients lose their hair and feel nauseated).
Why hair and nail grow if they are made up of dead cells?
There are cells in the epidermis (outer layer of the skin) which are alive and as they fill with keratin, they "push" forward and so the hair and the nails "grow". This appearance of growing is actually a sign that the cells at the skin are growing. The hair and the nails are dead. They can be cut as there is no feeling in them. If a person cuts the nails too short, that will hurt and bleed. See link below:
Never stops growing in the human body?
Hair and nails are two parts of the human body that never stop growing. This is because new cells continuously grow at the base of the hair follicles and nail beds, pushing the older cells outward. However, the rate of growth may slow down with age.
What makes your hair grow?
The keratin made by the hair follicle cells makes long fibers. The cells, growing just under the scalp, eventually die, leaving the keratin behind. This keratin, combined with the keratin left by many other cells, emerge from your scalp as hair.
