Most axons are covered with a protective sheath of myelin, a substance made of fats and protein, which insulates the axon. Myelinated axons conduct neuronal signals faster than do unmyelinated axons.

Can a myelinated axon have a larger diameter than an unmyelinated axon?
Unmyelinated fibers typically have smaller diameters than myelinated fibers.
Where is the axon not insulated with myelin?
Brain & spinal cord neurons are not myelinated
Along myelinated sections between nodes in a myelinated axon electrical signals are conducted by?
saltatorial conduction
Where do axon collaterals emerge on a myelinated nerve?
nodes of ranvier
Conduction along a myelinated axon is called?
It is called saltatory conduction. This describes the "jumping" of an action potential from node to node on a myelinated axon.
What type of axon allows saltatory conduction?
A myelinated axon
Can a myelinated axon have a larger diameter than an unmyelinated axon?
Unmyelinated fibers typically have smaller diameters than myelinated fibers.
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"
The neurolemma and the myelin of the myelinated axons are interrupted at regular intervals along the axon by?
The gap between each myelinated section of an axon is known the node of ranvier.
Where is the axon not insulated with myelin?
Brain & spinal cord neurons are not myelinated
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.
Along myelinated sections between nodes in a myelinated axon electrical signals are conducted by?
saltatorial conduction
White matter of brain composed?
myelinated axon of the neurons
Where do axon collaterals emerge on a myelinated nerve?
nodes of ranvier
Conduction along a myelinated axon is called?
It is called saltatory conduction. This describes the "jumping" of an action potential from node to node on a myelinated axon.
What give white matter its white color?
Myelin in the myelinated axon
COnduction speed of a nerve fiber would be the fastest in a?
...in a myelinated axon.
