Nervous System Question.?

I can’t seem to put these into order.
The question is : Put the following events in order as they occur in the nervous system of each person in the circle.
a. Nerve impulses generated by the pressure receptors travel along a sensory nerve to the spinal cord.
b. Pressure receptors in the left hand are triggered.
c. The brain intercepts the sensation as a “squeeze”
d. The nerve impulses are conducted along tracts in the spinal cord up through the medulla, pons, and midbrain to the somatic sensory cortex of the brain.
e. A nerve impulse travels from the primary motor cortex through the midbrain, pons, and medulla to the cortico-spinal tract within the spinal cord.
f. The primary motor cortex of the brain sends the instruction to use the right hand to squeeze the hand of the next person.
g. The impulse reaches effectors (muscles in the hand and arm).
h. The impulse travels from the spinal cord to the hand along a motor neuron.
i. The muscles are instructed to squeeze the hand of the next person.
I just know that b. is the first one. Does any one know what order this would go in?
