What is the advantage of faster conduction of nerve impulses?

What factors increase the speed of conduction along a neuron?

A myelin sheath on the axon of a neuron a. covers the axon completely. b. decreases the rate of impulse conduction c. increases the rate of impulse conduction d. has no effect on nerve impulse conduction

How does myelin increase the speed of nerve impulse conduction?

Describe the adaptive advantage of faster conduction of nerve impulses:

Comment on the significance of the differences between the speed and duration of nervous and hormonal controls:

(a) Explain why stimulating the first frog heart with electricity caused it to change its beating rate: _____ (b) Explain why the second heart in the experiment reduced its beating rate after a delay: _____

The water level of the reservoir in Austin, Texas, was 3 feet below normal. After a heavy rain storm, the water level increased to 5 feet above normal. How much did the rain storm change the water level?

What is the function of a neuron?

Explain how an action potential travels in a myelinated neuron.

(a) Name the neurotransmitter discovered by Loewi in his frog heart experiment: (b) Why was there a delay before the second heart in the experiment reduced its beating rate?

Identify the three basic components of a nervous system and describe their role: (a) ______ (b) ______ (c) ______

What is meant by saltatory conduction?

How does this differ from its travel in a non-myelinated neuron?
