This is a nursery rhyme.  Usually, nursery rhymes have lots of very simple words in them for little children to understand.  Just to be different, I’ve decided to give my nursery rhyme as many difficult words as I possibly can.  So here’s an explanation to what they mean:

NEURON: A type of cell (see ‘C’) that transmits electrical charges, and is important in the central nervous system (which is the system that helps us to think, feel and react).  Most of the neurons are in the brain, but there are also lots of neurons in the spinal cord and all over our bodies.
NOCICEPTOR: A type of neuron with the specific task of sensing pain.
RECEPTOR: A type of neuron with the task of sensing things from the outside world (so a nociceptor is a type of receptor, and a receptor is a type of neuron, and a neuron is a type of cell).
ACTION POTENTIAL: The signal that a neuron sends when it ‘fires’.
SYNAPSE: The little gap that separates the axon of one neuron from the dendrite of the next neuron.  Synapses are there so that information can only go one way along the axon, and are also thought to be very important in storing memories.
DENDRITE: The part of a neuron that receives information – through a synapse – from another neuron.
AXON: A thin thread stretching out of a neuron, which leads to another neuron, and along which information travels (in the form of action potentials).
MOTOR NEURON: A type of neuron located in the spinal cord which controls the movement of body parts.

Here are the words.
