Bipolar neurons have only one axon and one dendrite with the soma between them. There are probably very few, if any, neurons that contain only a single axon and dendrite. However, the concept is useful because some neurons behave as if they only had a single axon and dendrite. These neurons, called bipolar neurons because their cell body sits in between the axon and dendrite (giving the neuron two "poles"), are abundant in the nervous system. One very important type of bipolar neuron occurs in the retina, and is responsible for how we process light at an early level.
The part of the neuron that receives the majority of inputs is the dendritic tree. In most neurons its appearance is very similar to what a tree would look like in Autumn with no leaves. The part that carries information away and toward the dendrites of other cells is called the axon. There is only one axon per neuron and they can vary quite considerably in their length.
The part of the neuron that decides whether to send a message to the next neuron is the axon hillock. It acts as a gatekeeper by integrating incoming signals from other neurons and generating an action potential if the combined signals are strong enough to reach the threshold.
At the synapse, the electrical impulse between the two neutrons at synapse set of chain chemical reactions which create a chemical impulse at the synapse.
The myelin sheath covers the axon and speeds up nerve transmissions by insulating the axon and allowing for faster propagation of electrical signals.
myelin, although it is really only around the AXON of the neuron, not the whole neuron.
No, a neuron typically has only one axon which carries nerve impulses away from the cell body. However, certain types of neurons, such as those in invertebrates, can have multiple axon-like processes known as neurites that function in a similar way to axons.
No, each neuron has only one axon, but has multiple dendrites so it can receive information from multiple axons from other multiple neurons.

False.
A neuron has a large cell body that contains the nucleus, threadlike extensions called ­dendrites, and an axon. The dendrites carry impulses toward the neuron's cell body. The axon carries impulses away from the cell body. Nerve impulses begin in a dendrite, move toward the cell body, and then move down the axon. A neuron can have many dendrites, but it has only one axon. An axon, however, can have more than one tip, so the impulse can go to more than one other cell.Axons and dendrites are sometimes called nerve fibers. Nerve fibers are often arranged in parallel bundles covered with connective tissue, something like a package of uncooked spaghetti wrapped in cellophane. A bundle of nerve fibers is called a nerve.
