The most rapid nerve impulses are impulses that are carried?
The most rapid nerve impulses are carried by myelinated nerve fibers, which have a fatty sheath called myelin that enables faster signal transmission. These fast nerve impulses are crucial for quick reflex actions and communication between different parts of the body. Unmyelinated fibers are slower in transmitting nerve impulses compared to myelinated fibers.
Does a nerve provided impulses for many muscle fibers or just few?
A nerve can stimulate impulses to several muscle fibers. When muscle fibers are grouped they form a single muscle group like the biceps.
Do nerve impulses travel at 170 mph?
Nerve impulses do not travel at 170 mph; instead, they can vary significantly in speed depending on the type of nerve fiber. In myelinated fibers, impulses can travel at speeds up to about 120 meters per second (approximately 268 mph), while unmyelinated fibers are much slower. Thus, while some nerve impulses can approach high speeds, they do not typically reach 170 mph.
What is non-myelinated nerve fiber?
a nerve fiber that lacks the fatty myelin insulating sheath. Such fibers form the gray matter of the nervous system, as distinguished from the white matter of myelinated fibers. Also called nonmedullated nerve fiber.
What does non myelinated fibers look like?
Non-myelinated fibers appear as thin, unmyelinated axons within bundles of nerve fibers. They lack the myelin sheath that surrounds some other nerve fibers, which gives them a more transparent or grayish appearance compared to myelinated fibers. Non-myelinated fibers are typically smaller in diameter and conduct nerve impulses more slowly than myelinated fibers.
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.

Which Mineral is necessary for transmission of nerve impulses in the nerve fibers?
Zinc

Muscle fibers contract and relax in response to what?
nerve impulses
What carries odor impulses to the cerebrum for interpretation?
nerve fibers?
How fast nerve impulses travel?
Nerve impulses travel through nerve fibers, and the speed of which they travel depends on the type of nerve fiber. They travel usually around 86 miles per hour.
What is the optics?
It is a bundle of nerve fibers that carry electrical impulses to the brain from the retina.
How fast do nerves impulses travel?
Nerve impulses travel through nerve fibers via a action potential and the speed at which the impulse travels depends on the type of nerve fibre. This can range from 100m/s in the case of touch to 20-30 m/s when you're thinking.
What fibers are the most rapid nerve impulses conducted on?
These are nerves in animals. They include central and peripheral; peripheral include somatic and autonomic.

The bundles of neurons that transmit impulses over long distances are called?
The bundles of neurons that transmit impulses over long distances are called nerves. Nerves are composed of axons, which are the long fibers that carry electrical impulses from one part of the body to another.
