What else can I help you with?
Is shoulder flexion concentric or eccentric?
It depends on your position and if you are moving with or against gravity. If you are standing up right in anatomical position, and elbow extension is occurring after elbow flexion, then it is eccentric. When the elbow is moving into extension from flexion, it is moving downwards with the force of gravity. In order for this motion to occur, the biceps brachii has to lengthen, and the triceps brachii has to relax. The biceps brachii therefore is your primary mover. If elbow extension were occurring against the force of gravity (imagine your shoulder is flexed to 180 and your elbow is flexed, and you want to move it into extension while your shoulder is still flexed at 180), then it would be a concentric contraction and your primary mover would be your triceps brachii as it would be shortening to complete the motion. The biceps brachii would be your antagonist and it would be relaxing to allow the triceps to do its work. concentric= muscle shortening eccentric= muscle lengthening I hope this helps. I'm an OT student and this has been drilled into me.
What is the muscle between the elbow and shoulder?
the biceps
What is te primary function of biceps brachii muscle?
The primary function of the biceps is to supinate the hand. Secondary functions are bending the arm around the axis of the elbow and raising the elbow above the shoulder.(Source: Arthur Jones)
What is The muscle responsible for extension of the forearm?
Extension of the forearm at the elbow joint is achieved almost entirely by the triceps brachii but extension of the arm, which actually takes place at the shoulder joint, is achieved by muscles on the back, such as the latissimus dorsi.
What is the joint action during a shoulder press?
During a shoulder press, the primary joint actions are shoulder flexion and elbow extension. The shoulder joint allows for the movement of raising your arm overhead, while the elbow joint extends to push the weight up. Additionally, there is some scapular movement involved to stabilize the shoulder blades during the press.
What muscle is the primary mover for elbow flexion?
brachialis
What muscle is only responsible for elbow flexion?
The biceps brachii muscle is primarily responsible for elbow flexion. It crosses both the shoulder and elbow joints and is a strong supinator of the forearm.
What muscle adducts the shoulder and cause extension of the shoulder joints?
The latissimus dorsi, and the trees major, which is known as the " little lat", both adduct, extend, and internally(medially) rotate the shoulder. The long head of the triceps also extend and addicts the shoulder, while also being an elbow extensor
What is the difference between muscle flexing and and muscle extension?
when u flex it, it tightens, when u extend it, it stretches Flexion is when a muscle action decreases the angle at a joint, extension is when the angle increases. A simple example is bicep curl, flexion is when the hand is brought up towards the shoulder, decreasing the angle at the elbow joint. Just because a muscle is performing flexion or extension does not not mean it is contracting or stretching, that is eccentric and concentric movement. A muscle can still be tight when performing extension.
What is the primary joint movement for a lat pull down?
A lat pull down will move the shoulder and elbow the most, primary is probably shoulder.
Turbulate the difference between shoulder and elbow joints?
1. Shoulder joint is a synovial(ball and socket) joint. Whereas Elbow is a synovial(hinge) joint 2.Shoulder posses 3 degrees of freedom i.e Flexion, extension, abduction, adduction, medial and lateral rotations. Elbow have 1 degrees of freedom i.e flexion and extension 3.Difference of special structures i.e bursae 4.Shoulder is highly mobile than elbow
How does extension in the elbow occur?
The extension in the elbow occurs when the triceps muscle contracts, causing the forearm to straighten out. This movement is essential when performing actions like pushing and lifting objects.
