Anatomy Of The Upper Arm The upper arm is located between the shoulder joint and elbow joint. it contains four muscles – three in the anterior compartment (biceps brachii, brachialis, coracobrachialis), and one in the posterior compartment (triceps brachii). in this article, we shall look at the anatomy of the muscles of the upper arm – their attachments. The part below the elbow joint is referred to as the ‘lower’ arm or forearm. so, the 5 muscles in the upper arm are counted as the arm muscles. names & anatomy of the ‘upper’ arm muscles. the upper arm is divided into two compartments, the anterior (the front and inner side) and the posterior (the back and outer side). the group of 5.
Muscles Of Right Upper Arm Art Print By Asklepios Medical Atlas Anterior compartment. the anterior compartment contains three muscles: biceps brachii. coracobrachialis. brachialis. the major actions of the muscles of the anterior arm are flexion of the elbow (agonists) and shoulder (synergists). the anterior compartment derives its innervation from the musculocutaneous nerve (c5, c6, c7). The arm muscles are a group of five muscles located in the region between the shoulder and elbow joints. they are divided into two distinct compartments of the arm. the anterior (flexor) compartment contains the biceps brachii, coracobrachialis and brachialis muscles. the posterior (extensor) compartment contains only the triceps brachii muscle. Brachialis. this muscle lies underneath your biceps. it acts as a bridge between your humerus and ulna, one of the main bones of your forearm. it’s involved with the flexing of your forearm. Your arm muscles help you move your arms, hands, fingers and thumbs. you have many muscles in your upper arm and forearm. they allow you to do activities that require big movements, like swinging a baseball bat. they also control small, precise movements such as writing your name. to avoid an injury, take time to warm up before exercising.

There are some 650 skeletal muscles given latin names according to their location, size and shape, and action. the biceps brachii, for instance, is a two headed muscle (bi) of the arm (brachii). the main skeletal muscles of the arms are: biceps brachii. when you hold your arm out to the side with your palm up, the biceps is the muscle that sits. Figure 9.2.1 9.2. 1: the muscles of the arm. (cc by 4.0, openstax, human anatomy) on the posterior side of the arm is the triceps brachii muscle. it the antagonist to the biceps brachii. when the triceps brachii contracts it extends the forearm, undoing any flexing brought about by contractions of the biceps brachii.
