Spinal Injuries can cause loss of sensation and paralysis (loss of ability to move) in the legs. Choose ALL options that help to explain why this can happen.

• (Inter)neurons in the spinal cord carry messages between the brain and legs.

• If the spinal cord is damaged, sensory messages will not be able to go to the brain.

• If the spinal cord is damaged "movement" messages may not get to the muscles in the legs.

• There are no neurons in the spinal cord

• There are more touch receptive fields in the lips

• The touch receptive fields are more sensitive in the lips

• The touch receptive fields are bigger in the lips

Neurotransmission has both electric and chemical components. Select ALL that explain why they are needed.

• The axon carries an electric message along a neuron, to the end of the axon.

• Electric messages are stimulated in the synapse and each message travels along a single neuron, which they stop at.

• At the synapse, the electric message stimulates chemicals called neurotransmitters to cross the gap.

• Neurotransmitters cross the gap, and the electric message continues along to the next neuron.
