Answer
Hi again Sumaya;  These look like homework questions but I will answer the first one.

1. Touch receptors in the skin respond to any pressure. The pressure triggers a nerve impulse that travels along a sensory  neuron to the cord and then to the brain.  It  goes to the primary sensory are in the temporal lobe.  If a reaction to the touch is needed an impulse is sent to the motor areas.

2.The answer to this question is to long for me to go into and you can easily research this question.  Google the effects of alcohol and if you do not understand something get back to me
