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 does increasing the axon diameter also increase the speed of impulse conduction?
Larger diameter axons conduct impulses more rapidly than axons with a smaller diameter. Larger axons tend to be myelinated and conduct impulses rapidly. Myelin is a substance rich in lipid that forms an electrical insulation layer around the axon. This insulating myelin sheath allows impulses to be transmitted more rapidly then small diameter axons that are nonmyelinated.
Are impulses conducted rapidly if neurotransmitters are present?
Myelin
Why node of ranvier is present on myelinated axon?
Nodes of Ranvier are present on myelinated axons to allow for saltatory conduction, where the action potential jumps rapidly between nodes to increase the speed of conduction. By having gaps in the myelin sheath at the nodes of Ranvier, the action potential is able to regenerate at these points, leading to faster transmission of electrical signals along the axon.
Impulses are conducted rapidly if is present?
Myelin sheath. It is a fatty layer that surrounds the axon of a neuron and helps to speed up the transmission of electrical impulses along the neuron.
When impulses from various sources have an additive effect on a neuron the process is called?
When impulses from various sources have an additive effect on a neuron, the process is called summation. This can occur through temporal summation, where multiple impulses from the same source rapidly fire in succession, or spatial summation, where impulses from different sources converge at the same time to reach the neuron's threshold for firing.
Will glass or copper conduct heat the most rapidly?
Copper will conduct heat more rapidly than glass. This is because copper has higher thermal conductivity compared to glass, allowing heat to transfer more efficiently through the material.
What carries cardiac impulses to the myocardium?
Cardiac impulses are carried to the myocardium via specialized muscle cells called Purkinje fibers. These fibers are part of the cardiac conduction system and help to transmit electrical signals rapidly and efficiently throughout the heart muscle.
What kind of animal tissue functions in transmitting messages rapidly through the body?
Nervous tissue is the type of animal tissue that functions in transmitting messages rapidly through the body. It includes neurons that are specialized for conducting electrical impulses over long distances.
How many force modules are used to systematically and rapidly open an austere airfield establish operational capability and conduct air operations?
five
How do nerve impulses follow the fight or flight response?
During the fight or flight response, the brain perceives a threat and sends signals to the sympathetic nervous system to activate. This activation leads to the release of adrenaline, which binds to receptors on target cells, causing electrical impulses to travel rapidly along nerve fibers. These impulses prepare the body for physical action, such as increased heart rate and heightened senses, to deal with the perceived threat.
Is magnesium shiny and does it conduct heat and electricity?
Magnesium would only be shiny in a freshly cut surface. It quickly oxidizes with a film of protective oxide rapidly forming. In this condition it would look grey. It does conduct both heat and electricity.
Action potentials are conducted more rapidly when transmission is?
Myelinated. Myelin sheaths insulate nerve fibers, allowing the action potential to "jump" from one node of Ranvier to the next, a process known as saltatory conduction. This significantly increases the speed of signal transmission along the axon.
