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.
What else can I help you with?
What is the name of the movement the rotator cuffs allows the shoulder to make?
The rotator cuff consists of 4 muscles. They are responsible for providing stability during shoulder-joint movement.
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 is the primary trapezius muscle action during shoulder shrugging movements?
The primary action of the trapezius muscle during shoulder shrugging movements is to elevate and retract the shoulders.
What is the difference between abduction and adduction movements of the shoulder joint?
Abduction is when the shoulder moves away from the body, while adduction is when the shoulder moves towards the body.
What is the difference between shoulder abduction and adduction movements?
Shoulder abduction is when the arm moves away from the body, while shoulder adduction is when the arm moves towards the body.
What is the difference between shoulder adduction and abduction movements?
Shoulder adduction is when the arm moves towards the body, while shoulder abduction is when the arm moves away from the body.
What are the benefits of using the db shoulder press machine for shoulder workouts?
The benefits of using the dumbbell shoulder press machine for shoulder workouts include targeting and strengthening the shoulder muscles, improving shoulder stability, and allowing for controlled and isolated shoulder movements to prevent injury.
What are the movements involved in shoulder adduction and abduction?
Shoulder adduction involves moving the arm towards the body, while shoulder abduction involves moving the arm away from the body.
What are the differences between shoulder flexion and extension, and how do they impact the range of motion and function of the shoulder joint?
Shoulder flexion is the movement of raising the arm forward, while shoulder extension is the movement of bringing the arm backward. These movements impact the range of motion and function of the shoulder joint by allowing the arm to reach different positions and perform various tasks. Flexion helps with activities like reaching overhead, while extension is important for movements like throwing or pulling. Both movements are essential for a full range of motion and functional use of the shoulder joint.
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.
How does shoulder flexion abduction affect the range of motion in the shoulder joint?
Shoulder flexion and abduction increase the range of motion in the shoulder joint by allowing the arm to move forward and away from the body, respectively. These movements help to improve flexibility and mobility in the shoulder joint.
What are the benefits of using a dumbbell shoulder press machine for shoulder workouts?
Using a dumbbell shoulder press machine for shoulder workouts can help improve shoulder strength, stability, and muscle definition. It also allows for controlled movements and proper form, reducing the risk of injury.
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.
