Miranda is a sculpture artist, and part of her work involves putting clay into a kiln. One day, when removing pieces from the kiln, Miranda drops one she had been working on. She can’t work out why she dropped it; it was hot but she was telling herself not to drop it.

Why might Miranda have dropped the artwork?

• Miranda didn’t like the piece of art.

• Her motor neurons told her sensory neurons it was too hot.

• Her interneurons communicated quicker than she was thinking.

• Her sensory neurons carried a message to tell her muscles to let go.

Information from your central nervous system is communicated to the body’s organs via:

• interneurons

• motor neurons

• the spinal cord

• sensory neurons
