There are two types of neurons in our legs: motor neuron and sensory neuron. These send and receive messages to and from each other and the brain.
After Ed's accident, he can't move his injured leg since the motor neuron is dysfunctional. The sensory neuron is functional so he can feel his limbs but can't move them since when the sensory neuron sends a message to the motor neuron, it isn't able to deliver the message to the brain to make the leg move. This is why he can still feel his limbs but is not able to move them.

The five successive stages of coal
formation are as follows:
step 1: plants decay
step 2: peat is formed
step 3: peat changes to lignite (soft
brown coal made from peat)
step 4: bituminous coal is formed
(black and brittle and very polluting)
<span>step 5: anthracite coal is formed
(highest amount of carbon and clean burning)</span>
