multipolar neuron
A molecule is many order of magnitude smaller than a neuron. A neuron is made of molecules not the other way around.
It's normal for each neuron to have one thousand (1000) connections.

A neuron can have at most one axon. However, an axon can branch - sometimes many times.
The Inter-neuron (also known as the local circuit neuron, relay neuron or the association neuron) is the neuron which connects the afferent and the efferent neurons in the neural pathways.

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!
A molecule is many order of magnitude smaller than a neuron. A neuron is made of molecules not the other way around.
The cells that makes up the nervous system is the Inter-neuron (circuit neuron), sensory neuron and motor neuron.
The parts of a generic neuron are:- soma - cell body axon - upto 1 meter long dendrite - many
