The Triceps muscle is the most powerful extensor of the elbow and it is innervated by the radial nerve.
Triceps has three heads.
Long head originates from the Infraglenoid tubercle of scapula
Lateral and middle heads originate from posterior surface of shaft of humerus and between them have a groove called the radial/spiral groove through which passes the radial nerve and profunda brachi artery. In fractures of the midshaft of humerus, the radial nerve can thus be damaged.
All three heads joint to form a common tendon at back of elbow and attach to the olecranon process of the ulna

When flexing your arm you would use shoulder muscles, mainly the deltoids and pectoralis major. If you flex your elbow (which most people think means flexing your arm, but is really the forearm), then you would use your biceps, brachialis. and brachioradialis muscles, which would be three muscles, depending on the orientation of the forearm.
What muscles are used to drink a beer?
First you need to hold the beer. this involves flextion of the fingers. the muscles used for this is: flexor digitorum superficialis; flexor figitorum profundus; flexor pollocis longus. then you need to pronate your wrist. this uses : pronator teres; pronator quadratus; brachioradialis you also need to flex the elbow joint. this uses : biceps brachii; brachialis; brachioradialis then finally you need to abduct the shoulder: middle deltoid; suprispinatus; pectoralis major.
