Introduction to Ependymal Cell
Ependymal Cells Definition
Ependymal cells are cells that line the cavities of the brain and spinal cord. They are responsible for producing and secreting cerebrospinal fluid, which circulates through these cavities and helps to protect the brain and spinal cord from injury.
Ependyma
The ependyma is a type of ciliated epithelium that lines the cavities of the central nervous system, including the ventricles of the brain and the spinal cord. It is composed of columnar cells that have a single cilium at the apical surface. The cilia beat in a coordinated fashion to sweep fluid and debris from the surface of the cells. The ependyma also contains numerous microvilli that increase the surface area for absorption.
Structure
of an Atom
The atom is the smallest particle of an element that has the chemical properties of that element. The atom is made up of a nucleus and electrons. The nucleus is made up of protons and neutrons. The electrons orbit the nucleus.
Function
The function of the immune system is to protect the body from infection and disease. The immune system is made up of a network of organs, tissues, and cells that work together to protect the body. The immune system fights off germs and infections, destroys cancer cells, and repairs tissue damage.
Ependymal Epithelium
Ependymal epithelium lines the cavities of the brain and spinal cord. It is a ciliated, columnar epithelium that is responsible for the production of cerebrospinal fluid.
Ependymal Cells Function
Ependymal cells line the cavities of the brain and spinal cord and produce cerebrospinal fluid. This fluid bathes and cushions the brain and spinal cord and helps to remove waste products. Ependymal cells also play a role in the development and regeneration of nerve cells.
