Neurons come in many sizes. For example, a single sensory neuron from your fingertip has an axon that extends the length of your arm, while neurons within the brain may extend only a few millimeters. Neurons have different shapes depending on what they do. Motor neurons that control muscle contractions have a cell body on one end, a long axon in the middle and dendrites on the other end; sensory neurons have dendrites on both ends, connected by a long axon with a cell body in the middle.
There is a special cell in our body that is part of the nervous system. It receives messages in the muscles sent from the motor neurons in our brain. These cells are called effectors.
NEURONS
motor nerves are the one responsible sending messages to the brain..
those special child's . . .

yes longevity is a trait of neurons along with a high mebatolic rate and the lack of ability to divide (amitotic)
its based on christmas
they are called cones :)
When the action potential reaches the end of an axon, it causes special chemical messages called neurotransmitters to be released across the space between the neurons (the synapse).
