Question

Make a flow diagram showing the pathway of a nerve impulse when you pat at the shoulder of your friend.

Answer 1

Here is the flow chart indicating the nerve impulse

Answer 2

Flow diagram showing pathway of nerve impulse is shown below :

Explanation:

when a friend pat on the shoulder the response is carried :

stimulus-->receptor-->sensory nerve-->spinal chord --> motornerve -->effector-->response

here in a given condition the stimulus is a pat at the shoulder this information converts into chemicals (neurotransmittors)  and carried by receptors to the sensory nerves which takes this to the spinal chord in a central nervous system which gives reply to motor nerves which are present in muscels and gives the information to effector and it creates an response .
