Key Words: stimuli, receptors, impulses, sense organs, CNS, neurons, nerves, secretory organs
• Once a sensory receptor detects a stimulus, the information is sent in the form of an electrical impulse along cells known as neurons.

What is a receptor?
How do you respond to changes in
your surroundings?
Key Words: stimuli, receptors, impulses, sense organs, CNS, neurons, nerves, secretory organs
• Sensory Neurons carry nerve impulses from receptors in the body to the CNS.
• Motor Neurons carry nerve impulses from the CNS to the rest of the body

Key Words: stimuli, receptors, impulses, sense organs, CNS, neurons, nerves, secretory organs
• Impulses that travel along motor neurones cause effector organs like muscles or glands to respond.
• Muscles contract and glands secrete chemical substances.
