multipolar neuron
Myelin sheath. This is the insulating sheath which covers most of the axon, between the Axon Hillock and Collateral branches of the Neuron.
A molecule is many order of magnitude smaller than a neuron. A neuron is made of molecules not the other way around.

A neuron can have at most one axon. However, an axon can branch - sometimes many times.
The nervous system is composed of many cells called neurons, these are essentially the functional units of the nervous system. ?Neurotrnasmitters are chemical messengers that are sent from one neuron to another neuron. ?So basically they are messangers communicating from one neuron to the next. ?Some neurotransmitters are excitatory which act to help activate a neuron, some neurotransmitters are inhibitory and act to reduce excitement of a neuron. ?Many many neurotransmitters will act on a neuron at a given time and the sum total will result in either an excitation or inhibition of that neuron. ?Examples of neurotransmitters include GABA, glutamate, serotonin, dopamine, acetylcholine, histamine, ?glycine, epinephrine, norepinephrine, melatonin, substance P, and many more!
