_is the structural and functional units of the nervous system
Answers
Answer:
Nerve Cells
Although the nervous system is very complex, nervous tissue consists of just two basic types of nerve cells: neurons and glial cells. Neurons are the structural and functional units of the nervous system. They transmit electrical signals, called nerve impulses. Glial cells provide support for neurons. For example, they provide neurons with nutrients and other materials.
Neuron Structure
As shown in Figure below, a neuron consists of three basic parts: the cell body, dendrites, and axon. You can watch an animation of the parts of a neuron.
The cell body contains the nucleus and other cell organelles.
Dendrites extend from the cell body and receive nerve impulses from other neurons.
The axon is a long extension of the cell body that transmits nerve impulses to other cells. The axon branches at the end, forming axon terminals. These are the points where the neuron communicates with other cells.
The structure of a neuron allows it to rapidly transmit nerve impulses to other cells.
