What muscles are involved in shoulder abduction?
The primary muscles involved in the action of arm abduction include the supraspinatus, deltoid, trapezius, and serratus anterior.
What muscles do shoulder adduction?
Adduction is accomplished primarily by the pectoralis major, latissimus dorsi, teres major, triceps, and coracobrachialis. The deltoid and the supraspinatus, a muscle that runs along the scapula in the back, are the two main abductors of the shoulder.
Which joint is comprised of the Humeroulnar and Humeroradial joints?
The humeroulnar and humeroradial articulations of the elbow joint are served by the musculocutaneous, radial, and ulnar nerves.
What is a glenohumeral joint effusion?
Joint effusion is where the fluids in the tissues around your joint increase causing your knee, shoulder, ankle or other joint swells up. Treatments help heal the swelling by addressing the cause.
What are the 3 joints of the elbow?
Three joints form the elbow:
- Ulnohumeral joint enables movement between the ulna and humerus.
- Radiohumeral joint enables movement between the radius and humerus.
- Proximal radioulnar joint enables movement between the radius and ulna.
Which of the following muscles are antagonists?
In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist….Antagonistic muscle pairs.
| Biceps | Triceps |
|---|---|
| Pectoralis major | Latissimus dorsi |

What muscles does horizontal adduction?
The muscles that horizontally abduct your upper arm are your posterior deltoid, infraspinatus and teres minor. The muscles that horizontally adduct your upper arm are your middle deltoid, coracobrachilis, pectoralis major and latissimus dorsi.
