## Step 1
The peripheral nervous system (PNS) is a part of the nervous system that consists of the nerves and ganglia outside of the brain and spinal cord. Its main function is to connect the central nervous system (CNS) to the limbs and organs. Essentially, the PNS is responsible for transmitting information to and from the CNS.

## Step 2
The PNS is responsible for controlling various parts of the body. These include the muscles, which allow us to move, the skin, which allows us to feel touch, and the organs, which perform various functions such as digestion and respiration.

## Step 3
Medications can affect the PNS in several ways. Some medications can stimulate the PNS, increasing the activity of the nerves and muscles. Others can depress the PNS, reducing the activity of the nerves and muscles. This can be useful in treating conditions such as high blood pressure or certain types of pain.
