Myelin Sheath is basically fat-containing cells that insulates the neurons from any electric impulses that travel along the nerves and makes sure that the impulses do not jump between close nerves

∙ 9y agoThe axon branch off a neurons are covered by myelin sheath to give insulation to the same. Myelin sheath is made up of cells, which come from mesoderm.

Are the nodes of ranvier only found on myelinated peripheral neuron processes?
Yes.
Is white matter dense in myelinated axons?
Yes White matter is the part of the nervous system that is dense is myelinated axons
What part of the neuron would be responsible for notifing the brain that you hurt yourself?
Sensory nerve fibers carry message to brain. A part of neuron or or single neuron does not carry this message to the brain.
How many synapses occur in this reflex arc?
there are 2 - one between the sensory and relay neurones; the other between the relay and motor neurones.
What part of the neuron sends information to others?
Presynaptic neuron sends postsynaptic receives
Does a worm have a myelinated or non-myelinated neuron?
non-myelinated
What is speed of myelinated neuron?
50 m/sec
Are muscles and glands myelinated?
Muscles and glands are not myelinated. It is the axon of a neuron that is myelinated. The myelin forms a layer called myelin sheath that makes the nervous system function properly.
Are the nodes of ranvier only found on myelinated peripheral neuron processes?
Yes.
The speed of nerve impulse transmission through the axon of a sensory neuron will be quickest in?
I'm guessing; "myelinated nerve fibres" contrary to the much slower "non-myelinated nerve fibres"
Which type of cell produces the myelin covering around the axon of a neuron?
In the central nervous system, neuronal axons are myelinated by oligodendrocytes. In the peripheral nervous system axons are myelinated by Schwann cells.
What is the output structure of a neuron?
The axon is the output structure of a nerve cell. Many times it is myelinated like an electrical wire.
Does impulse travel faster along myelinated neuron?
Yes, impulses travel faster in myelinated axon rather than in unmyelinated. It is mostly due to nodes of Ranvier. Instead of travel along the axon, in myelinated axon impulses "jump" from node to node. Also there are two types of myelinated axons: type A and type B. (Type C in unmyelinated axon.) Type A is the fastest among all of them.
Is white matter dense in myelinated axons?
Yes White matter is the part of the nervous system that is dense is myelinated axons
Which animal cell is sometimes called a neuron?
a neuron is a nerve cell
What is white matter in the brain composed of?
largely or entirely composed of nerve fibers and contain few or no neuronal cell bodies or dendrites.
What part of a neuron relays signals from one neuron to another neuron or to an effector?
synaptic terminal
