The shoulder joint, being one of the most mobile joints in the body, show quite a lot of versatility in it's movements.
It shows flexion(150°-170°), extension (40°), abduction (160°-180°), adduction (30°-40°), lateral rotation (in abduction: 95°; in adduction: 70°) and medial rotation (in abduction: 40°-50°; in adduction: 70°).
Flexion is when your muscles bulge, like when you show off your biceps. Extension is the opposite of flexion, when you unbend your elbow. Abduction is when you raise your arm away from your body and adduction is when you lower your arm. Lateral rotation is when you rotate your arm outwards and medial is when you rotate your arm inwards.
The shoulder can perform several movements, including flexion (raising the arm forward), extension (bringing the arm backward), abduction (lifting the arm to the side), adduction (bringing the arm back to the body), internal rotation (rotating the arm inwards), and external rotation (rotating the arm outwards).

What is the name of the movement the rotator cuffs allows the shoulder to make?
The rotator cuff allows the shoulder to perform movements such as rotation, abduction, and extension.
What is the scientific name for a collar bone?
The scientific name for the collar bone is clavicle. It is a long bone that connects the arm to the body and helps with shoulder movements.
What is the scientific names for the shoulder muscle?
The scientific name for the shoulder muscle is the deltoid muscle.
What is the scientific name for shoulder girdle?
The scientific name for the shoulder girdle is "pectoral girdle." It is the set of bones that connect the upper limbs to the axial skeleton.
Scientific name of the collarbone?
The scientific name for the collarbone is the clavicle. It is a long bone that serves as a strut between the shoulder blade and the sternum. Its main function is to provide support and mobility to the shoulder.
The shoulder girdle is responsible for which movements of the scapula?
The shoulder girdle is responsible for movements such as protraction, retraction, elevation, depression, and upward and downward rotation of the scapula.
What causes crackling shoulder sound?
Crackling or popping sounds in the shoulder can be caused by air bubbles moving in the joint or tendons rubbing over bone. It can also occur due to muscle or ligament movements during certain shoulder movements. If the sound is not accompanied by pain or limited range of motion, it is usually harmless.
What movement can the shoulder joint not do despite being a multi-axial joint that allows a variety of movements?
Flexion, extension/hyperextension, trabsverse horizontal abduction, circumduction.If you think about the movements that you can do at your shoulder, you can figure this question out yourself. When in the anatomical position, we can perform flexion and extension,the forward and backward (respectively) movements of our arm at the shoulder joint. There is also abduction and adduction, which is the movement of rising our arm out to our sides, away from our body (abduction) and towards our body (adduction). Finally, there is also medial rotation and lateral rotation of the shoulder joint, in which we rotate the head of humerus in the shoulder-joint cavity (glenoid cavity). You may hear the combined movements of flexion, extension, abduction and adduction referred to as circumduction.
Muscle that adducts shoulder and causes extension of the shoulder joint?
The latissimus dorsi muscle is responsible for adducting the shoulder and causing extension of the shoulder joint. It is a large triangular muscle located in the back that helps with various movements of the shoulder and arm.
When the arm is raised a located at the shoulder is responsible for this movement?
The deltoid muscle, specifically the anterior portion of the deltoid, is primarily responsible for raising the arm at the shoulder joint. This muscle is located on the outer part of the shoulder and is involved in various arm movements, including shoulder abduction.
What effect does the glenoid cavity have on the shoulder joint?
the glenoid cavity is where the bone from the arm does all it's movements. it's essentially the "socket", if you consider the shoulder joint a ball and socket joint.
What are the primary joint movements of a lat pulldown exercise?
shoulder adduction, elbow flexion and scapular downward rotation
What are the advantages of a mobile shoulder girdle?
A mobile shoulder girdle allows for a wide range of arm movements, improving overall upper body flexibility and function. It also helps in performing various tasks that require reaching, lifting, and rotating movements with ease. This mobility can enhance sports performance and reduce the risk of shoulder injuries.
What is the name of the movement the rotator cuffs allows the shoulder to make?
The rotator cuff allows the shoulder to perform movements such as rotation, abduction, and extension.
What plane is elevation of the shoulder girdle?
The plane of elevation of the shoulder girdle is the scapular plane, which is at approximately a 30-degree angle from the frontal plane of the body. This plane is important for proper movement of the shoulder joint and can help reduce impingement and stress on the shoulder muscles and tendons. It is often used as a reference point for exercises and movements involving the shoulder.
The sternal portion of the pectoralis major is most active in?
The sternal portion of the pectoralis major is most active during movements that involve horizontal adduction of the shoulder joint, such as hugging or pressing movements. It also contributes to shoulder flexion and internal rotation when the arm is raised in front of the body.
What is a superficial muscle of the neck and upper back acts at the shoulder This muscle is the?
The trapezius muscle is a superficial muscle of the neck and upper back that acts at the shoulder. It is responsible for movements like shoulder shrugging, scapular elevation, depression, retraction, and rotation.
