What cells undergo mitosis in humans?
Three types of cells in the body undergo mitosis. They are somatic cells, adult stem cells, and the cells in the embryo. Somatic cells – Somatic cells are the regular cells in the body of multicellular organisms.
What type of cells result after meiosis quizlet?
Each daughter cell is diploid (contains the normal number of chromosomes). Meiosis produces 4 daughter cells, each of which are unidentical to the parent cell and to one another. Each daughter cell is haploid (contains half the number of normal chromosomes).
What types of cells are produced by mitosis?
Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
What type of cells are involved in mitosis?
mitosis / cell division. Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
What is the end product of mitosis quizlet?
What is the end product of Mitosis? Two identical daughter cells.
Where are hair cells in ear?

Can damaged hair cells in ear regenerate?
Unlike their counterparts in other mammals and birds, human hair cells cannot regenerate. So, once hair cells are damaged, hearing loss is likely permanent.
What damaged hair cells in ears?
A one-time exposure to extreme loud sound or listening to loud sounds for a long time can cause hearing loss. Loud noise can damage cells and membranes in the cochlea. Listening to loud noise for a long time can overwork hair cells in the ear, which can cause these cells to die.
How do you fix damaged hair cells in your ear?
While damaged auditory hair cells can be compensated for with the use of hearing aids, there is no replacement or cure for damaged vestibular hair cells. Hair cells do not function in isolation, but need to be connected to the auditory centers of the brain through nerve fibers.
How do you protect hair cells in your ear?
The most effective strategies used to prevent hair cell loss after noise-induced damage are: (1) use of antioxidants, (2) inhibition of programmed cell death pathways, (3) anti-inflammatory therapies, and (4) neurotrophic factors.
What are hair cells in the ear called?
The cochlear hair cells in humans consist of one row of inner hair cells and three rows of outer hair cells (see Figure 13.4). The inner hair cells are the actual sensory receptors, and 95% of the fibers of the auditory nerve that project to the brain arise from this subpopulation.
Can ear hair cells repair themselves?
In humans and other mammals, damaged sensory hair cells in the inner ear are unable to divide or regenerate themselves, and there are no drugs that will help restore lost hearing. As a result, most cases of hearing loss (90 percent) are permanent.
