Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of neuron has many extensions that arise from the cell body?
A
unipolar
B
bipolar
C
multipolar
D
None of the above
Explanation: 

Detailed explanation-1: -A multipolar neuron has the highest number of structures extending from the cell body. There is only one axon, but each cell has many dendrites, making it easier for the neuron to exchange information.

Detailed explanation-2: -Motor neurons have the most common type of ‘body plan’ for a nerve cell-they are multipolar, each with one axon and several dendrites.

Detailed explanation-3: -Dendrites. Dendrites and axons are cytoplasmic extensions, or processes, that project from the cell body. They are sometimes referred to as fibers. Dendrites are usually, but not always, short and branching, which increases their surface area to receive signals from other neurons.

Detailed explanation-4: -Multipolar neurons are the most common type of neuron. They are located in the central nervous system (brain and spinal cord) and in autonomic ganglia. Multipolar neurons have more than two processes emanating from the neuron cell body.
