The scapulothoracic joint is not a true joint in the sense in that it has no capsule or ligamentous attachments. It is more precisely identified as the scapulothoracic articulation. It is formed between the anterior scapula and the posterior thoracic rib cage(ribs 2-7). The scapula's attachment to the axial skeleton in a healthy shoulder is purely musculotendinous in nature, formed by the trapezius and serratus muscles. Its gliding movement patterns consist of elevation/depression, retraction/protraction, and superior/inferior rotation. However, fibrous adhesions can sometimes occur following a shoulder injury, particularly if the joint has been immobilized for a long period of time. This severely impairs the movement of the shoulder, particularly with abduction past 90 degrees.
During the concentric phase of a reverse fly exercise, the shoulder joint primarily goes through horizontal abduction as the arms move outward away from the body. The scapulothoracic joint also engages to stabilize the shoulder blades and maintain proper alignment. This coordinated action involves the posterior deltoid and other muscles of the upper back to perform the movement efficiently and effectively.
The term for muscles that cause or control joint motion through a specified plane of motion is called agonist muscles. These muscles are primarily responsible for producing movement around a joint while the antagonist muscles perform the opposite action to allow for smooth and controlled motion.
The muscles around the pivot joint are the Quadricep and the Hamstring muscles.

Some recommended exercises for strengthening the muscles around the intermediate joint to prevent injury and improve overall joint stability include squats, lunges, leg presses, and calf raises. These exercises target the muscles around the joint, such as the quadriceps, hamstrings, and calf muscles, helping to improve strength and stability. It is important to perform these exercises with proper form and gradually increase the intensity to avoid injury.
Muscles that bend a joint are flexors; musces that straighten a joint are extensors.
No, it is the opposite. Muscles that bend a joint are called flexors, while muscles that straighten a joint are called extensors. For example, the biceps are flexors of the elbow joint, and the triceps are extensors of the elbow joint.
The rotator cuff muscles in the shoulder joint help to stabilize and rotate the arm bone (humerus) within the shoulder socket. They also assist in lifting and rotating the arm, as well as maintaining proper shoulder joint function during various movements.
Opposing muscles use connective tissues to cause movement in a joint.
