Arm Body Part – Anatomy of the Arm
An arm is the upper limb or forelimb of vertebrates, such as humans and primates. It’s also known as the brachium in human anatomy. The arm is made up of three sections: the upper arm, forearm, and hand. It extends from the shoulder joint to the fingers and contains 30 bones, including the humerus in the upper arm and the radius and ulna in the forearm.
Major muscles, such as the biceps and triceps, enable flexion and extension. The brachial plexus provides the arm with motor and sensory innervation. Blood is supplied by the brachial, radial, and ulnar arteries and tendons and ligaments provide structural support and stability.

Bones and Muscles in the Arm
The arm body part is the upper limb of vertebrates. Anatomy of the arm involves the detailed study of its bones, muscles, nerves, blood vessels, and connective tissues. Learning about the arm muscles and arm bones helps in understanding how movements are coordinated and how injuries can be prevented or treated.
In this article, we will cover the anatomy of the arm and read about the nerve supply and blood supply in the arm along with arm muscles and bones, in detail.
