1. Understanding the Anatomy of the Upper Arm

Before diving into the reasons behind upper arm pain, it’s essential to grasp the basic anatomy. The upper arm, also known as the brachial region, extends from the shoulder to the elbow. It primarily consists of a single long bone called the humerus, which connects to the shoulder blade (scapula) at the shoulder joint and the radius and ulna (the forearm bones) at the elbow joint.

1.1 Muscles of the Upper Arm

Several muscles in the upper arm are responsible for movement and stability:

Biceps brachii: Located on the front of the upper arm, it flexes the elbow and supinates the forearm.
Triceps brachii: Found on the back of the upper arm, it extends the elbow.
Brachialis: Located deep to the biceps brachii, it’s a primary elbow flexor.
Coracobrachialis: A smaller muscle that assists in flexing and adducting the arm at the shoulder.

1.2 Nerves and Blood Vessels

The upper arm also houses vital nerves and blood vessels:

Brachial artery: The main artery supplying blood to the upper arm and forearm.
Median, radial, and ulnar nerves: These nerves provide sensory and motor function to the arm and hand.
