The Spinal Cord
The ability to think and feel
Through contact between the dendrites of one neuron and the axon branches of the next
Through neurotransmitting chemicals that float between the synapse space
Through electrochemical signals that pass from axon to axon
By an electrical current that is transmitted from the dendrite of the first neuron to the axon branch of the second neuron
From the brain
To the brain
Branches off the brain and spinal cord and is responsible for muscle movement.
Is connected to the central nervous system and is responsible for gathering sensory information.
Responsible for collecting and acting on information that is interpreted by the brain.
Connects the central nervous system to the environment to gather sensory input and create motor output.

A cell where sounds are converted into electrical signals
A region in a cell membrane that receives electrical impulses
A specialised structure that is sensitive to a specific external stimulus
Motor neurons engage muscles and face flinches away from bug
Electrical impulse passed out of CNS and carried to the PNS through motor neurons
Sensory information carried via sensory neurons through the PNS to the CNS
Sensory information reaches the CNS inter-neuron relay
The celiac wished that gluten had no affect on her digestive system
The celiac wished that gluten didn't affect her digestive system
Sensory information is passed through the afferent pathway to the control centre where it is interpreted
Nerve impulse are sent from the control centre along the afferent pathway to the muscles
