There are two main ones, the tricep and the biscep. The tricep bicep is on the inside angle as defined by your elbow, the tricep is on the outside.
The biceps is a word meaning the muscles on the upper arm.
There are many arm muscles. The triceps (on the back of your upper-arm) contract when you straighten your arm, and the biceps (the front of the upper-arm) relaxes.
Arm curls primarily work the biceps muscles in the front of the upper arm.

Those muscles are called the triceps.
There are approximately 20 muscles in the human arm that control its movements, including muscles in the shoulder, upper arm, forearm, and hand.
The bicep is in you arm from your elbow to your shoulder
Muscles in your arm.These are the muscles of your upper arm.
The upper arm is primarily composed of skeletal muscle. Specifically, muscles such as the biceps brachii and triceps brachii are responsible for movement and stability in the upper arm. These muscles are attached to the bones by tendons and are under voluntary control.
Muscles that do not move the upper arm primarily include those that act on the forearm and wrist. Key examples are the brachialis, brachioradialis, and the muscles of the forearm, such as the flexor and extensor groups. Additionally, muscles in the shoulder region, like the rotator cuff muscles (except for the supraspinatus) and some of the pectoral muscles, stabilize the shoulder but do not directly move the upper arm itself.
Biceps brachii muscle, is a muscle located on the inside of the upper arm Biceps femoris muscle, is one of the hamstring muscles at the back of each thigh
there is only two muscles in the upper arm, the triceps and the biceps
