True or False? A neuron contains more than one axon.
Please explain. Ty!

(this is just a guess) False because no neuron ever has more than one axon; however in invertebrates such as insects the axon sometimes consists of several regions that function more or less ...
Neurons have different shapes and sizes, but all have the same basic structure. They have a central core, located in a roughly spherical area of the neuron, called cell body. From the cell body come out fine branched extensions. These extensions are called dendrites. From the cell is detaching a single, long fiber, called the axon, the main fiber which provides the leading of the signal to the nerve.
So, the statement that a neuron contains more than an axon is false!
True, a neuron contains hundreds and hundreds of axon's. Axon's transmit impulses away from the cell body whereas dendrites conduct impulses towards the body of the neuron. One nerve consist of an axon covered my a Schwann cell(protective covering), which is then encased in a endoneurium(another protective covering), which is then encased by a fasicle which is a "nerve bundle". All this is encased by the epineurium(final protective covering). Axon's provide for rapid transmission of impulses to distal or distant locations of the body. Nerve cells also contain blood vessels such as arteries and veins that supply the nerve with it's blood supply. You have millions of neurons in your body that are either motor neurons or sensory neurons. Motor neurons make something happen whereas sensory neurons transmit sensory information like touch and pressure.
The cell body of a neuron frequently gives rise to multiple dendrites, but never to more than one axon, although the axon may branch hundreds of times before it terminates.
BUT only a few neutrons actually have axons.
