What is the name of the upper arm bone quizlet?

The humerus is the only bone of the upper arm. It is a long, large bone that extends from the scapula of the shoulder to the ulna and radius of the lower arm. The proximal end of the humerus, known as the head, is a round structure that forms the ball of the ball-and-socket shoulder joint.

What is the shoulder bone called?

The shoulder is made up of three bones: the scapula (shoulder blade), clavicle (collarbone) and humerus (upper arm bone). Two joints in the shoulder allow it to move: the acromioclavicular joint, where the highest point of the scapula (acromion) meets the clavicle, and the glenohumeral joint.

What are the names of the bones in the upper arm?

The bones of the upper arm include the: 1 Scapula. The scapula is also called the shoulder blade. 2 Clavicle. The clavicle is also called the collarbone. 3 Humerus. The humerus is a long bone in the upper arm.

Where does the humerus bone of the arm connect?

The elbow joint is where the humerus bone of the upper arm connects with the radius and ulna bones in the forearm. The elbow joint is actually composed of three separate joints: Ulnohumeral joint. This is where the humerus connects to the ulna.

Where is the ulna bone in the arm?

Ulna: This forearm bone runs from the elbow to the “pinkie” side of the wrist. The elbow can move in three ways based on slight variations in the positions of the heads of the three bones. The first is the large hinge action that is used in most movements of the arms, such as holding bags of groceries or doing bicep curls.
