Nervous system cells are called neurons. They have three distinct parts, including a cell body, axon, and dendrites. ... While there are billions of neurons and thousands of varieties of neurons, they can be classified into three basic groups based on function: motor neurons, sensory neurons, and interneurons.

The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord.

The brainstem is divided into three sections in humans: the midbrain (mesencephalon), the pons (metencephalon), and the medulla oblongata (myelencephalon).

The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.

The brain has three main parts: the cerebrum, cerebellum and brainstem. Cerebrum: is the largest part of the brain and is composed of right and left hemispheres.

What are the parts of the nervous system? The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

What are the three general functions of the nervous system? sensory, integrative, and motor.

A typical neuron consists of a cell body and neuronal processes such as dendrites and axon. ... These extensions are the conducting region of the neuron. Nerve impulses are generated in the axon and transmitted away from the cell body towards the synapse. The cell body is the major biosynthetic center of the neuron.

Neuron. Neurons (also known as neurones, nerve cells and nerve fibers) are electrically excitable cells in the nervous system that function to process and transmit information. In vertebrate animals, neurons are the core components of the brain, spinal cord and peripheral nerves.
1213036
The cells in nervous tissue that generate and conduct impulses are called neurons or nerve cells. These cells have three principal parts: the dendrites, the cell body, and one axon. The main part of the cell, the part that carries on the general functions, is the cell body.

['Sensory neurons send impulses from sensory receptors to inform the CNS of a stimulus. ... ', 'Motor neurons send impulses from the CNS to the muscle, organ or gland they command to take action. ... ', 'Inter neurons receive information from other neurons and pass this information on to other neurons.']
