2. Reaction times increase and coordina-
and temperature, are carried by
A fibers. Motor impulses to skeletal muscles are also carried by A fibers.
These types of impulses relay information about the external surroundings and how the body will respond to external stimuli. The speed with which these impulses are carried could reduce the incidence of injury to the body by allowing for a quick reaction to a stimulus.
3. Student answers will vary. Sample answer: Two factors that influence the speed with which an impulse is conducted are the diameter of the axon and whether or not it is myelinated. In the absence of myelination, increasing the diameter of the axon will increase the speed of impulse conduction. The large axons in the organisms are responsible for the escape or withdrawl reflexes.
