Hair cells in the inner ear are nourished by the surrounding fluid in the cochlea, called the endolymph. This fluid provides essential nutrients and oxygen to the hair cells to help maintain their function in detecting sound waves. Damage to the hair cells or changes in the composition of the endolymph can lead to hearing loss.

What organ does hair grow from?
Hair grows from hair follicles, which are found within the skin of mammals. Each hair follicle is connected to blood vessels and nerves, allowing hair to grow and be nourished with essential nutrients.
How is a hair formed?
Each hair develops from a group of epidermal cells at the base of a tubelike depression called a hair follicle, which extends from the surface into the dermis and contains the hair root. The epidermal cells at the base are nourished from dermal blood vesssels in a projection of connective tissue at the deep end of the follicle. As these epidermal cells divide and grow, older cells are pushed toward the surface. The cells that move upward and away from the utrient supply become keratinized and die. Their remains constitute the structure of a developing hair shaft that extends away from the skin.
What are hair cells made up of?
Hair cells in the inner ear are specialized sensory cells that detect sound waves. They are made up of stereocilia, which are tiny hair-like projections that are critical for detecting and transmitting sound signals to the brain. Hair cells translate mechanical vibrations into electrical signals that the brain can interpret as sound.
Are root hair cells living or dead?
Root hair cells are living cells. They are specialized cells found in plant roots that absorb water and nutrients from the soil. These cells have extensions (root hairs) that increase the surface area for absorption.
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.

Cells receive nourishment from the blood. The blood carries molecules that are broken down from food in the digestive system.
What is it called when the bodys cells are nourished and energized?
Cellular metabolism is the process by which the body's cells are nourished and energized through the breakdown of nutrients and production of energy. This process involves various biochemical reactions that allow cells to function and carry out their basic functions.
WHAT IS The process in which the body's cells are nourished and energized?
The process in which the body's cells are nourished and energized is called cellular respiration. During cellular respiration, cells break down glucose into energy in the form of adenosine triphosphate (ATP) through a series of biochemical reactions. This process occurs in the mitochondria of cells and is essential for the maintenance of cellular functions.

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.
