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.

Which impulses are faster myelinated or unmyelinated?

Myelinated nerves conduct impulses faster than unmyelinated nerves. The myelin sheath acts as an insulator that allows for faster transmission of nerve signals by increasing the speed at which the action potential travels down the axon.


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 are the differences between myelinated and unmyelinated nerve fibers in terms of their conduction speed and efficiency?

Myelinated nerve fibers conduct electrical signals faster and more efficiently compared to unmyelinated nerve fibers. This is because the myelin sheath insulates and speeds up the transmission of signals along the nerve fibers.


How do the conduction velocities of unmyelinated axons compare to myelinated axons?

Unmyelinated axons have slower conduction velocities compared to myelinated axons. Myelinated axons are able to conduct nerve impulses faster due to the insulation provided by the myelin sheath.


Which nerve fiber do impulses travel slowly?

Unmyelinated nerve fibers conduct impulses more slowly than myelinated nerve fibers. Myelinated nerve fibers have a fatty substance called myelin sheath that allows for faster transmission of impulses compared to unmyelinated fibers without this sheath.


Can a myelinated axon have a larger diameter than an unmyelinated axon?

Yes, a myelinated axon can have a larger diameter than an unmyelinated axon. Myelin sheath covers the axon, and the diameter of the axon itself can vary independently of myelination. The larger diameter of a myelinated axon allows for faster conduction of nerve impulses compared to unmyelinated axons.


Why are myelinated axons faster than unmyelinated axons?

Myelinated axons are faster than unmyelinated axons because the myelin sheath acts as an insulator, allowing for faster transmission of electrical signals along the axon. This insulation helps to prevent signal loss and allows the electrical impulse to "jump" from one node of Ranvier to the next, a process known as saltatory conduction, which speeds up the transmission of the signal.


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.


What is the relationship between the degree of myelination and and conduction velocity?

That myelinated axons fare faster, unmyelinated are 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.
