What are our Receptors?
Our sense organs
INFO (TURN THE CARD)
Sensory nerves -> Inter nerves -> Motor nerves
What are Sensory Neurons?

What are Inter Neurons?
Neurons found within the CNS and transfer impulses between the other neurons.
What are Motor Neurons?
They transmit impulses from the CNS to effectors (like muscles).
