Introductory Assignment to the Nervous System
... The brain takes the message from the sensory neurons and decides if a response is necessary. The brain decides the response should be to cover eyes with hands. This message leaves the brain via a motor neuron. The motor neuron deadends in a muscle, telling the muscle to contract and jerk up the arms ...

Note: This hypothesis is mainly concerned with peripheral neurons
... In vitro assays have shown that NTs enhance both axonal and dendritic growth In vivo, the situation is more difficult to study Why? In standard knockouts, it is difficult to separate the survival effects of NTs from their effects on the morphology of neurons. This problem has begun to be addressed ...
