The gustatory pathway has a more complicated course. There are more fiber tracts involved in the transmission of the neural impulses for taste. The facial nerve transmits gustatory signals or messages from the anterior two-third of the tongue. However, for the posterior one-third of the tongue,the glossopharyngeal nerve is responsible for the transmission of the gustatory signals along the pathway.
Motor neurons
spinothalamic, it is a somatosensory pathway
By providing an alternative pathway with a lower activation energy.
An abnormal, rapid heart rhythm, due to an extra pathway for the electrical impulses to travel from the atria to the ventricles.
A catalysts speed up the rate of reaction by providing an alternate pathway which has a lower energy of activation than the normal pathway.
An enzyme works by providing an alternate pathway for the reaction, and one that has a LOWER activation energy than the original pathway without the enzyme. It thus speeds up the reaction.
Axons conduct the nerve impulses. Dendrites receive the impulses. Possible the impulses go through the dendrites faster, though the synaptic cleft may slow this pathway. Dendrites are much shorter than axons.

synaptic gaps.
a nerve cell forming part of a pathway along which impulses pass from the brain or spinal cord to a muscle or gland.
