shoulders (deltoids) and chest (pectorals).
Most of the muscles of the body are exercised when running. Of course the foot and leg muscles are needed the most but the muscles of the torso and upper body are used as well.
The muscles most often affected are those that are near the central part of the body, such as muscles of the chest and the upper arms and legs.
movement is caused by the contraction(shortening) of muscles.
Most commonly one exercises skeletal muscles. For example, the quadraceps in the upper-leg, biceps in the upper-arms, or the pectoral muscles of the chest (used in push-ups) are some of the most obvious muscle groups.
Most of the work is being done by your leg muscles, but the upper body sees some activity as it keeps you balanced and upright.

primarily the biceps, also the pectorals (pecs), and shoulder, and abs (most of the upper body really)
Of course.
For the most part its biceps and triceps. but back and shoulder muscles are very important too.
The traditional pull up is a so-called `compound` exercise, which means it targets most of the muscle groups of the upper body (so basically it trains your entire upper body fairly equally). In my experience though, the muscles which grew tired the most after every pull up workout and in long-term grew the most were the obliques and shoulder muscles.
