What substances carry a nerve impulse?
Neurons and their axons
What transmits a nerve impulse at the highest rate?
Large myelinated axons.
What is the material surrounding the axon that increases the speed of the nerve impulse?
myellin
What is the correct order that information passes through in a neuron?
The flow of information across nerve cells is called a nerve impulse in which the axons of the cell must depolarize, repolarize and go through a refractory period before reaching the resting potential. At this point, another impulse can occur.
The axons of the retina culminate in what nerve?
the axons of the retina culminate in the optic nerve which forms a blind spot on the retina
What is a nerve impule transmitted by axons?
It is called a nerve impulse.
What substances carry a nerve impulse?
Neurons and their axons
What transmits a nerve impulse at the highest rate?
Large myelinated axons.
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.
Also called a nerve impulse transmitted by axons?
action potential
Is a nerve message also called a synapse?
Nerve messages are called an impulse. Synapses are the space between two axons.
Why does the frog sciatic nerve give a graded response?
The frog schiatic nerve gives a graded response because the nerve is a bundle of axons and not a single axon (thus it does not show the all or none response of an axon-either generating an action potential or not). If one axon is generating an action potential then a small nerve impulse is witnessed, if all axons are simultaneously generating action potentials then a large nerve impulse is witnessed. Thus the nerve impulse is graded (it can be none, small, medium, large, larger, maximal).
What is the material surrounding the axon that increases the speed of the nerve impulse?
myellin
What are Bundles of axons are called?
NERVES
How do nerve axons enhance speed of nerve impulse transmission?
By being wrapped in myelin sheaths, produced by Schawann cells in the peripheral nervous system and oligodendrocytes in the central nervous system.
What minimizes leakage of the electrical current traveling along the axon?
The nodes of Ranvier along myelinated axons in sensory nerve fibers minimize leakage of the nerve impulse electrical signal.
Where do axons from the olfactory nerve project to?
Axons from the olfactory nerve project directly to the
