For example, the biceps muscle, in the front of the upper arm, is a flexor, and the triceps, at the back of the upper arm, is an extensor. When you bend at your elbow, the biceps contracts. Then the biceps relaxes and the triceps contracts to straighten the elbow.
What happens when you pull on a biceps muscle?
The most common symptom of a bicep tear or strain is pain in the upper arm, which can lead to bruising, muscle spasms, or loss of mobility and strength. Typically, nonsurgical treatments like rest, ice, and non-steroidal anti-inflammatory medications can help provide relief from your symptoms.
What happens to the biceps when the arm moves?

How do biceps move your arm?
The biceps includes a “short head” and a “long head” that work as a single muscle. … The tendon that attaches the biceps muscle to the forearm bones (radius and ulna) is called the distal biceps tendon. When the biceps contracts, it pulls the forearm up and rotates it outward.

Is the brachialis part of the bicep?
The brachialis (brachialis anticus), also known as the Teichmann muscle, is a muscle in the upper arm that flexes the elbow. It lies deeper than the biceps brachii, and makes up part of the floor of the region known as the cubital fossa (elbow pit).
