Do myelinated nerve fibers conduct signals faster than unmyelinated fibers?

Yes, unmyelinated axons, action potentials are generated at sites immediately adjacent to each other and conduction is relatively slow. Degree of myelination speeds up transmission.

Does an unmyelinated fiber conduct impulses faster than a myelinated fiber?
False
What nueron conducts impulses faster?
Myelinated neurons conduct impulses faster than unmyelinated neurons.
What is meant when axon is described as myelinated?
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.
Which impulses are faster myelinated or unmyelinated?
Neural transmission is different and MORE rapid in myelinated neurons
What is the relationship between the degree of myelination and and conduction velocity?
That myelinated axons fare faster, unmyelinated are slower.
A myelinated nerve fiber is characterized as being whereas an unmyelinated?
Myelinated nerves are white, and composes the white matter of the brain and spinal cord they also are able to pass an action potential down an axon much faster; Unmyelinated nerves are gray, and composes the gray matter of the brain and spinal cord. These nerves transmit signals much slower
What is the relationship between nerve size and conduction velocity?
velocity proportional to square root of diameter
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.
What impulse conduction is the fastest in neurons?
Axons conduct the nerve impulses. Dendrites receive the impulses. Possible the impulses go through the dendrites faster, though the synaptic cleft may slow this pathway. Dendrites are much shorter than axons.
Unmyelinated fibers conduct impulses more rapidly than myelinated fibers?
Other way, dude. Nerve fibers are just like electric wires. Just think of a Myelinated fiber as a wire with rubber on the outside, and unmyelinated with ought it. Electricity runs more efficiently through a wire that has rubber on it, and so do myelenated fibers, but with an added bonus, they are faster than their unmyelenated counterparts hope it helped!
Why are nerves myelinated?
Some neurons are myelinated so they can carry signals faster.
Would conduction speed of a nerve fiber be the fastest in a large or small myelinated fiber?
Yes. Myelinated fibers have a myelin sheath around them which keeps the impulse from scattering and on a direct path. This makes the impulse travel faster than unmyelinated fibers.
