One end of the tRNA contains an anticodon loop which pairs with a mRNA specifying a certain amino acid. The other end of the tRNA has the amino acid attached to the 3' OH group via an ester linkage. tRNA with an attached amino acid is said to be charged. The enzyme that attaches the amino acid to the 3'-OH is called an aminoacyl tRNA synthetase (aaRS). There is a specific tRNA for each amino acid, 20 in all.
With this tool, they have been able to identify and treat a shoulder injury called a glenoid labrum tear. The shoulder joint has three bones: the shoulder blade (scapula), the collarbone (clavicle), and the upper arm bone (humerus). The head of the upper arm bone (humeral head) rests in a shallow socket in the shoulder blade called the glenoid. The head of the upper arm bone is usually much larger than the socket, and a soft fibrous tissue rim called the labrum surrounds the socket to help stabilize the joint.
Many of us think that pain in shoulder blade is the same as shoulder pain. This statement isn't correct! Many a time, pain in the shoulder blade has nothing to do with the shoulder itself.The shoulder is interconnected with many tissues and muscles.The soft tissues surrounding the shoulder are known as 'rotator cuff' which are made from 4 muscles which connect to the collarbone and the shoulder blade.he cause can be diagnosed well by studying the case history of the person and analyzing the range of motion (ROM) of a person's arm movement. Various tests are done based on the condition to determine the cause and treatment for pain in shoulder blade. The following are included under the list of causes.
