Response time of a neural pathway is considered.

This job names factors that contribute to the response time of a neural pathway, giving an explanation for each factor. It also offers an example of how one of these factors affects speed of transmission in the visual system as a brief overview.

Neural Response Time

There are several things that could lead to differences in neural response time and most of them are based in the physical structure of the neuron itself. There are a few examples of exogenous (things from outside the body) that can have an effect on the response of a neuron.

One of the major factors that contributes to response time is the presence of, or lack of, a myelin sheath around an axon. A myelin sheath protects the signal in an axon and makes it move along much faster than if the neuron had no myelin surrounding it. Neurons in the visual system are almost all myelinated and very fast.
