By extension almost any object that performs this function of attaching one part to another (usually larger) component is also called a bracket ...
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 .

There are four types (depending upon displacement of the radial head): [3] Bado Classification - Monteggia Fractures. I - Extension type (60%) - ulna shaft angulates anteriorly (extends) and radial head dislocates anteriorly.
Jazelle DBX (direct bytecode execution) [1] is an extension that allows some ARM processors to execute Java bytecode in hardware as a third execution state alongside the existing ARM and Thumb modes. [2] Jazelle functionality was specified in the ARMv5TEJ architecture [3] and the first processor with Jazelle technology was the ARM926EJ-S. [4]
Significant pain, sometimes felt along the arm past the shoulder. Sensation that the shoulder is slipping out of the joint during abduction and external rotation. [6] Shoulder and arm held in external rotation (anterior dislocation), or adduction and internal rotation (posterior dislocation). [6] Resistance of all movement. Numbness of the arm.
The development of the Third Arm began in 2015 as a collaborative effort in ARL’s Human Research and Engineering Directorate (HRED) and Weapons & Research Materials Directorate (WMRD). [4] The project was an attempt to improve the marksmanship of soldiers by finding ways that would make the use of heavier, more lethal firearms and larger ...
