Reflex Actions

Flowchart nodes

• Detects stimuli and sends information as an electrical impulse  

• Receptor

• Sensory neuron

• CNS (Central nervous system)

• Carries electrical impulse to the CNS

• Made up of the brain and spinal cord, it co-ordinates the information and sends impulses back out around the body

• Motor Neurons

• Carries impulses from the CNS around the body to effector organs

• Effector organs

• Effector organs are muscles or glands, muscles react by contracting and glands react by secreting chemical substances

• Relay neurons (connect the motor and sensory neurons, found in the CNS)
