What else can I help you with?
What is a nerve impule transmitted by axons?
It is called a nerve impulse.
What will conduct a nerve impulse faster thick or thin axon?
Thick axons conduct nerve impulses faster than thin axons because they have a lower resistance to the flow of electrical signals. This allows for quicker transmission of signals along the axon.
What direction does nerve impulse travel?
Along a nerve cell, the impulse travels from the axon to the dendrites and then again to the axons through the synapse.
What is the difference between synaptic and nerve impulse transmission?
Synaptic transmission is chemical, while nerve impulse or axonal transmission is electrical.
What transmits a nerve impulse at the highest rate?
Myelinated nerve fibers transmit nerve impulses at the highest rate due to the presence of insulation provided by the myelin sheath. This insulation helps the nerve impulse jump quickly from one node of Ranvier to the next, allowing for rapid transmission.
How does the diameter of the axon affect the rate of nerve impulse transmission?
The diameter of the axon significantly influences the rate of nerve impulse transmission, with larger diameters allowing for faster conduction. This is primarily due to reduced internal resistance to the flow of ions, enabling quicker depolarization and repolarization of the membrane. Additionally, larger axons can facilitate the effectiveness of myelination, which further speeds up impulse transmission through saltatory conduction. Thus, thicker axons generally result in more rapid signal propagation compared to thinner ones.
Also called a nerve impulse transmitted by axons?
action potential
Which two characteristics of axons increases the speed of nerve impulse?
diameter and presence of myelination.....
What is the difference in transmission between myelinated and unmyelinated fibers?
Impulse transmission on an unmyelinated nerve fiber is much slower than the impulse transmission on a myelinated nerve fiber.
Why does a reflex nerve pathway move faster than a normal nerve transmission?
Reflex nerve pathway is a monosynaptic transmission. There are no interneurons involved. Only the limb that carries the afferent nerve impulse from the stimulus and the efferent motor function for the reflex involved. That is why it is faster. Normal nerve transmission require an interpretation of the impulse by the brain whereas reflex pathways do not. Another reason is because most reflexes from the exteroreceptors travel along myelinated axons (white matter) which carry the impulse faster than other neurons that have unmyelinated axons (grey matter).
What is nerve impulse transmission?
An action potention.
Is a nerve message also called a synapse?
Nerve messages are called an impulse. Synapses are the space between two axons.
