the axons and dentrites would get mixed up and the brain would be thinking in two ways and we would be confused to which one was which

What are the most rapid action potentials conducted on?
thick myelinated axons
The most rapid action potentials are conducted on?
thick, myelinated axons.
What is a tiny branching thread-like structure found in neurons?
There are two possible answers - axons or dendrites. Axons carry action potentials away from the neuron, while dendrites receive action potentials.
What is the association of axons with nerves?
Axons conduct the nerve impulses, or action potentials, to the axon terminals and the synaptic cleft.
Which structure if the neuron transmits an impulse through the myelin sheath?
Neural impulses (action potentials) are transmitted through axons which are covered in a myelin sheath for insulation.
Do axons carry action potentials away from the cell body?
The areas that have had the action potential are refractory to a new action potential.
What is salutatory conduction?
Saltatory conduction refers to the propagation of action potentials along myelinated axons from one node of Ranvier to the next node. It increases the conduction velocity of action potentials.
What nerve is composed of axons of the ganglion cells and transmits action potentials the thalamus of the brain?
Optic nerve
What is the high-speed signals that pass along the axons of nerve cells called?
The high-speed signals that pass along the axon are called action potentials. They spread in a wave of depolarization.
How does the long axon help in a nerve cell?
The axons are long so that action potentials can be sent from one part of the body to another very quickly. If instead of one long axon we had loads of individual cells there would be a much bigger delay because the action potentials would have to be converted to chemical signals very fequently and that takes time.
Do myelinated nerve fibers conduct signals faster than unmyelinated fibers?
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.
Also called a nerve impulse transmitted by axons?
action potential
