Sometimes, depending on the type and function of the neuron, and when it does, it will be on the AXON of the neuron, not the whole neuron.
The AXONS of grey matter in the brain do NOT have a coating, but white matter in the brain DOES, as do longer axons in the peripheral nervous system. The Myelin Sheath which coats white matter in the brain is made up of glial cells called oligodendrocytes, and the myelin sheath around peripheral nerve cells are called Schwann cells.

What neuron is before a synapse?
The synapse consists of the two neurons, one of which is sending information to the other. The sending neuron is known as the pre-synaptic neuron (i.e. before the synapse) while the receiving neuron is known as the post-synaptic neuron (i.e. after the synapse).
What is a presynaptic neuron?
a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.
What is the first motor neuron in an autonomic pathway called?
The first motor neuron in an autonomic pathway is called a preganglionic neuron. It originates in the central nervous system and synapses with a postganglionic neuron in an autonomic ganglion.
What is a motor neuron attached to?
A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.
What happens when a substance gets into a neuron?
When a substance enters a neuron, it can bind to receptor sites on the neuron's membrane, triggering a cascade of events within the neuron. This can lead to changes in the neuron's electrical activity, release of neurotransmitters, or alterations in gene expression, ultimately affecting the neuron's function.
This structure of the neuron plays a role similar to the rubber coating?
Myelin sheath, comprised of glial cells wrapped around an axon one after another (oligodendrocytes in the CNS, schwann cells in the PNS).
Where is the neuron?
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.
Why is a neuron called an interneuron?
A neuron is called a inter-neuron because that specific neuron takes impulse from one neuron to a next neuron. For example your sensory neuron sends a impulse that you had felt a hot object. It goes through the spine to a inter-neuron to a motor neuron (this processes is called a reflex). Then the motor neuron tells your muscles in your hand to move
Define relay neuron?
a relay neuron is the neuron that picks up the message from the sensory neuron and delivers it to the motor neuron in the spinal cord or the brain
What is the 3 types of neuron?
one type of neuron is the motor neuron
What is intermixed neuron?
a neuron which recieve both messages from afferent and efferent neuron...
What type of neuron connects to a muscle?
A motor or efferent neuron.
What is a neuron impulse?
it is neuron impulse
What is another name for afferent neuron?
sensory neuron or receptor neuron.
Is motor a neuron?
motor neuron is a type of neuron that found at the muscles, tissues, and organs.
Why is there a fatty coating around the neuron?
The myelin sheath around nerve tracts insulate and protect the nerve from too much stimulation and it also makes the electrical current, that is used to feel and move, move faster through the body. People who lack the myelin sheath have serious and life threatening problems because their bodies do not move when it is supposed to, one common disorder of demyelination is multiple sclerosis.
What effects do neurotransmitters from the neuron have on the next neuron?
The neurotransmitters from one neuron have direct effect on the next neuron. They are channels that are used to transmit messages in the nerves.
