Muscles And Actions

The correct answer provides the specific muscle (Trapezius) and its different actions on the scapula at various regions. The incorrect answers offer other muscles and their actions which do not align with the question asked.

Rhomboids are responsible for scapular elevation, adduction, and downward rotation, which are different movements compared to those associated with the other muscles mentioned in the incorrect answers.

The Levator scapulae muscle is responsible for scapular elevation, adduction, and downward rotation.

The correct answer is Pectoralis Minor, which is responsible for scapular forward tilt. The incorrect answers are: Rectus Abdominis is responsible for hip flexion, Biceps Brachii is responsible for shoulder abduction, and Hamstrings are responsible for knee extension.

The question is testing knowledge of muscles and their corresponding actions. The serratus anterior muscle is responsible for scapular abduction, which involves moving the shoulder blades away from the spine. The trapezius muscle is involved in shoulder shrugging, the pectoralis major muscle is responsible for shoulder adduction, and the deltoid muscle is involved in shoulder flexion.

The subscapularis muscle is responsible for shoulder internal rotation, while deltoid is responsible for abduction, trapezius for retraction, and biceps brachii for elbow flexion.

The correct answer is supraspinatus which is responsible for shoulder abduction, while the incorrect answers do not match the muscle and action described in the question.

The teres minor muscle is responsible for shoulder external rotation, while the deltoid muscle is responsible for shoulder abduction, the triceps brachii muscle is responsible for elbow extension, and the biceps brachii muscle is responsible for elbow flexion.

The correct muscle for shoulder extension is latissimus dorsi which is responsible for pulling the upper arm downwards and backwards. The action of shoulder extension involves moving the arm backwards from an anatomical position.

The correct answer is teres major which is responsible for shoulder extension.

The correct muscle for shoulder horizontal adduction is the pectoralis major, as it is responsible for bringing the arm across the body in a horizontal motion. The deltoid is responsible for shoulder abduction (moving the arm away from the body), the biceps brachii is responsible for elbow flexion, and the trapezius is responsible for scapular elevation (shoulder shrugging).

The correct muscle and action pair is coracobracialis for shoulder adduction. The incorrect answers provided do not match the correct pair and actions associated with them.

The deltoid muscle is responsible for various movements in the shoulder joint, including flexion, abduction, and horizontal abduction.

The triceps brachii muscle is responsible for extending the elbow, not flexing it. The biceps brachii is actually responsible for elbow flexion. The deltoid muscle is responsible for shoulder abduction, not elbow extension. The soleus muscle is responsible for ankle plantarflexion, not elbow extension.

The anconeus muscle is responsible for elbow extension. The deltoid muscle is involved in shoulder abduction, the gluteus maximus muscle is responsible for hip extension, and the biceps brachii muscle is involved in elbow flexion, not knee extension.

The biceps brachii muscle is responsible for elbow flexion, while the triceps brachii muscle is responsible for extension. The deltoid muscle is primarily responsible for abduction of the shoulder, not elbow flexion. The serratus anterior muscle is responsible for protraction of the scapula, not elbow flexion.

The correct muscle responsible for elbow flexion is the brachialis, which contracts to bend the arm at the elbow joint.

The correct answer is pronator teres which is responsible for forearm pronation, not the other muscles mentioned.

Forearm pronation is primarily carried out by the pronator quadratus muscle, which is responsible for rotating the forearm inward.

The correct answer relates to the supinator muscle which is responsible for forearm supination, rotating the palm upward. The incorrect answers are muscles associated with different actions such as elbow flexion, shoulder abduction, and knee extension.

The correct answer is the brachioradialis muscle, which is responsible for multiple actions including elbow flexion, forearm supination, and forearm pronation. The incorrect answers provided each represent different muscles with specific actions that are not equivalent to the actions of the brachioradialis.

Flexor carpi radialis and flexor carpi ulnaris are responsible for wrist flexion and radial(or)ulnar deviation. The other incorrect options do not perform the specific muscle action required for the given question.

The correct answer is 'palmaris longus wrist flexion'. The palmaris longus muscle is a long, slender muscle located on the anterior aspect of the forearm. Its action is to flex the wrist, which involves moving the hand towards the inner part of the forearm.

The extensor carpi ulnaris is responsible for extending the wrist and deviating it towards the ulnar side, whereas the other muscles mentioned are responsible for different actions.

The correct muscle for wrist extension and radial deviation is the extensor carpi radialis longus. Flexor digitorum superficialis, Brachioradialis, and Pronator teres are not responsible for this specific movement.

The correct muscle responsible for wrist extension and radial deviation is the extensor carpi radialis brevis.

The extensor digitorum muscle is responsible for extending the MCP joint of four fingers. Flexor digitorum, abductor pollicis longus, and infraspinatus are not involved in MCP joint extension of four fingers.

The muscle responsible for thumb abduction is the abductor pollicis longus, which moves the thumb away from the palm of the hand.

The extensor pollicis longus muscle is responsible for the IP extension of the thumb, actively moving the thumb in an upward direction.
