By the end of the lesson you should be able to
Describe the transmission of impulses from senses to central nervous system and back to muscles.
Describe the reflex action and the pathway of the reflex arc.
Describe the function of reflex response. Describe the role of the central nervous
system.

Sensory neuronsSensory neurons
Carries impulses from receptors e.g pain receptors in skin to the CNS( brain or spinal cord)

Relay neuronRelay neuron
Carries impulses from sensory nerves to motor nerves.

Motor neuronMotor neuron
Carries impulses from CNS to effector e.g. muscle to bring about movement or gland to bring about secretion of hormone e.g ADH
