Anatomy of lower arm. In human anatomy the arm is the part of the upper limb between the glenohumeral joint shoulder joint and the elbow joint. The lower arm or forearm bone is the radius. It has two long bones known as the ulna and the radius.

Additionally the biceps brachii operates as a supinator of the forearm by rotating the radius and moving the palm of the hand anteriorly. On the posterior side of the upper arm is the triceps brachii which acts as an extensor of the forearm at the elbow and the humerus at the shoulder. The radius is long and curved in shape and runs parallel to the ulna.

Anterior compartment there are three muscles located in the anterior compartment of the upper arm biceps brachii coracobrachialis and brachialis. Muscles attached to the radius include. This is known as nerve compression or a pinched nerve.

Extending from the shoulder to the elbow the upper arm provides pulling and lifting strength. The term forearm is used in anatomy to distinguish it from the arm a word which is most often used to describe the entire appendage of the upper limb but which in anatomy technically means only the region of the upper arm whereas the lower arm is called the forearm. That means pain from a shoulder injury such as a torn rotator cuff often radiates down your arm.

In this article we shall look at the anatomy of the muscles of the upper arm their attachments innervation and actions. It can be divided into the upper arm which extends from the shoulder to the elbow the forearm which extends from the elbow to the hand and the hand. The brachioradalis muscle connects the humerus upper arm bone to the radius shortest lower arm bone and aids in flexing the elbow.

The coracobrachialis muscle the deltoid muscle. Your arm especially your forearm and wrist is a common area for this. The flexor digitorum superficialis.

The forearm is the area between the wrist and the elbow. The forearm is the area that lies between the elbow and the wrist. In common usage the arm extends to the hand.

It is important to first understand the anatomy of the forearm as any disease disorder or injury of these structures may be the reason for forearm pain. It is homologous to the region of the leg. Several of the muscles in your upper arm are connected to your shoulder.

The flexor pollicis longus. This hinged joint allows the arm to open up to 180 degrees at full extension.
