Anatomy & Physiology Nervous #6
Which is the primary type of cell in the nervous system?
Glial cells are supportive cells in the central nervous system. Glial cells, unlike neurons, do not conduct electrical impulses.
An axon is a long threadlike part of a nerve cell. The axon is responsible for impulse conduction from the cell body to other cells.
Myelin is a mixture of phospholipids and proteins that form a whitish insulating sheath around many nerve fibers. Myelin increases the speed at which nerve impulses are conducted.
Neurons are specialized cells that transmit nerve impulses. They are considered the primary cell type in the nervous system.
The nervous system, a complex collection of specialized cells and nerves, transmits signals between different parts of the body.
Neurons are the primary nervous system cells. Neurons communicate with each other in unique ways. The neuron is the basic working unit of the brain that is designed to transmit information not only to other nerve cells but to gland cells and muscles also.
