Question

Trace the sequence of events which occur when a bright light is focused on your eyes

Answer 1

Answer:

• they carry the stimuli to the spinal cord which transports the message to the brain
• the brain revert back the message by the motor neurons which contract the Pupil.
• The sequence of events which occur is as follows:-

Receptors ->sensory neurons -> brain ->motor neurons ->eye muscles-> pupil
