Multipolar has a number amount of axons ____
A
one
B
two
C
three
D
four
Explanation: 

Detailed explanation-1: -Multipolar neurons are the most common types of neurons in the CNS; they form the autonomic ganglia. They possess a single axon with several symmetrically radiating dendrites.

Detailed explanation-2: -Each multipolar neuron contains one axon and multiple dendrites. Multipolar neurons can be found in the central nervous system (brain and spinal cord). The Purkinje cell, a multipolar neuron in the cerebellum, has many branching dendrites, but only one axon.

Detailed explanation-3: -An anaxonic neuron is a type of neuron where there is no axon or it cannot be differentiated from the dendrites.

Detailed explanation-4: -The axons of multipolar neurons are often very long and can conduct action potentials throughout the brain, down the spinal cord, and along the nerves.

Detailed explanation-5: -No neuron ever has more than one axon; however in invertebrates such as insects or leeches the axon sometimes consists of several regions that function more or less independently of each other. Axons are covered by a membrane known as an axolemma; the cytoplasm of an axon is called axoplasm.
