The upper arm is the humerus, the lower arm is made up of the radius and ulna. The joint connecting the upper is called the humeroulnar joint.
There are two joints between the forearm bone and wrist:the midcarpal jointthe radiocarpal jointthe radiocarpal joint is the first from the forearm.condyloid joint
Glenohumeral Joint
The joint between the shoulder and the wrist is the elbow.
The glenohumeral joint which is also known as the "shoulder joint"
Your shoulder joint allows you to raise your arm above your head.
The ball-and-socket joint of the shoulder allows the upper arm to be raised and lowered.
An elbow is a joint that helps you bend your arm.
The "Elbow" is the joint of your arm.
It is a triangular muscle covering the shoulder joint, it raises the arm from the side of the body
Ball and socket joint The arm movement is possible because of ball and socket joint.
The upper arm is the humerus, the lower arm is made up of the radius and ulna. The joint connecting the upper is called the humeroulnar joint.
elbow joint
The deltoid sits on top of the glenohumeral joint and helps to abduct and also to rotate the humerus.

There are actually more than 4 muscles that should be immobilized. When you move your shoulders you move your clavicle. The muscles that causes movement at the shoulder joint should be immobilized. This includes the prime movers, as well as the assistant movers. The following muscles should be immobile. The subclavius which moves and depresses the clavicle as well as helps stabilize the pectoral girdle. The pectoralis minorabduct the scapula and rotates it downward, lowering your shoulders. The serratus anterior abducts the scapula and cause it to rotate upward, shrugging your shoulders. The trapezius stabilizes the scapula as well as move it, and helps extend head. The levator scapulae elevates the scapula and rotates it downward. The rhomboid majorelevates, adducts, rotates downward, and stabilizes the scapula. The Rhomboid minor does the same thing as the Rhomboid major. The pectoralis major adducts and medially rotates the arm at the shoulder joint; flexes arm at the clavicular head and extends the arm to the side of the trunk at the sternocostal head. The deltoid abducts the arm at the shoulder joint; flex and medially rotates the arm at shoulder joint; and extend and laterally rotates the arm at shoulder joint. The subscapularis medially rotates the arm at shoulder joint. The supraspinatus assists the deltoid muscle to abduct the arm at the should joint. The infraspinatuslaterally rotates and abducts the arm at the shoulder joint. The teres major extends the arm at the shoulder joint and assists in the adduction and medial rotation of the arm at the shoulder joint. The teres minor laterally rotates, extends, and adducts the arm at the shoulder joint. The coracobrachialis flexes and adducts the arm at the should joint.
For the lower ball joint, remove the lower control arm and the ball joint seal. Press the ball joint from the control arm. Press the new ball joint into the lower control arm ensuring it is fully seated, install a new seal and the lower control arm.
