Respuesta :
The basic element of the nervous system is the nerve cell, or neuron. In combination, neurons form nerves, fibers that transmit impulses throughout the body. A protective covering of myelin, a fatty substance, insulates parts of the fibers.
The neuron, also known as a nerve cell, is the most fundamental component of the nervous system. Its duty is to send information from one cell to the next.
Nervous system and nerve cell:
The nerve cell does this by containing unique fibres that stretch from the cell body's cytoplasm. Dendrites carry impulses from the cell to the cell body.
The nerve cells, which are formed into long processes are called axons along which nerve impulses travel, are the basic parts of the nervous system. The bodies of nerve cells can be grouped together to form ganglia, and nerves are made up of bundles of axons.
