Brevis moves the arm from ulnar abduction to its mid-position and flexes dorsally. Longus is a weak pronator in the flexed arm and a supinator in the outstretched arm. At the carpal joints longus acts in dorsiflexion with the extensor carpi ulnaris and in radial abduction with the flexor carpi radialis. These two muscles are called "fist ...
The latissimus dorsi is responsible for extension, adduction, transverse extension also known as horizontal abduction (or horizontal extension), [1] flexion from an extended position, and (medial) internal rotation of the shoulder joint. It also has a synergistic role in extension and lateral flexion of the lumbar spine.
Abduction is an anatomical term of motion referring to a movement which draws a limb out to the side, away from the median sagittal plane of the body. It is thus opposed to adduction . Upper limb
There's an easy way to remember the difference between abduction and adduction. Ready for a quick, simple trick that'll finally make the distinction between abduction vs. adduction stick ...
Abduction is carried out by the deltoid and the supraspinatus in the first 90 degrees. From 90-180 degrees it is the trapezius and the serratus anterior. Adduction is carried out by the pectoralis major, latissimus dorsi, teres major and the subscapularis. Horizontal abduction and horizontal adduction of the shoulder (transverse plane)
At the glenohumeral joint, movement of the humerus is performed by a combination of transverse abduction, by the posterior and lateral deltoids, [3] and external rotation, by the infraspinatus and teres minor. [4] At the scapulothoracic joint, the middle and lower fibers of the trapezius and the rhomboids contract to perform retraction of the ...

The plasma field has a radius of about 100μm-200μm around the electrodes and is kept stable within the head of the coblation wand by the continuous supply of saline. Furthermore, the plasma field is controlled by the bipolar energy between the negative and positive ions that are produced by the plasma in order to use a precise amount of ...
