The long part of a nerve cell, it brings impulses away from the cell body.
|
|

None of the above

Detailed explanation-1: -The cell body, also called the soma, is the spherical part of the neuron that contains the nucleus. The cell body connects to the dendrites, which bring information to the neuron, and the axon, which sends information to other neurons.
Detailed explanation-2: -The region of the neuron containing the nucleus is known as the cell body, soma, or perikaryon (Figure 8.2). The cell body is the metabolic center of the neuron.
Detailed explanation-3: -The cell body is the largest part of the neuron that contains the nucleus and cytoplasm. The cell body is also called the soma.
Detailed explanation-4: -Most of the cell bodies of neurons are in the central nervous system (brain and spinal cord), or in the ganglia (which lie just outside the spinal cord) of the peripheral nervous system. The axon: a single nerve ‘fibre’ which transmits impulses to the distal end.
Detailed explanation-5: -The cell body (also called the soma) is the spherical part of a neuron that houses the nucleus. It also contains all the other organelles essential for cell survival and plays a key role in supplying energy, proteins, and other materials to the axon.
