Retraction= Middle trapezius Elevation= Upper trapezius
Rhomboideus major and rhomboideus minor inserted at the medial border of the scapula, supplied by dorsal scapular nerve (c5) retracts and elevates the scapula. these are also …called as tha brassiers of the scapula.

styloglossus: retracts the tongue, elevates side
The scapulothoracic joint is not a true joint in the sense in that it has no capsule or ligamentous attachments. It is more precisely identified as the scapulothoracic a…rticulation. It is formed between the anterior scapula and the posterior thoracic rib cage(ribs 2-7). The scapula's attachment to the axial skeleton in a healthy shoulder is purely musculotendinous in nature, formed by the trapezius and serratus muscles. Its gliding movement patterns consist of elevation/depression, retraction/protraction, and superior/inferior rotation. However, fibrous adhesions can sometimes occur following a shoulder injury, particularly if the joint has been immobilized for a long period of time. This severely impairs the movement of the shoulder, particularly with abduction past 90 degrees.
rhomboids and middle trapezius
When the joint is bent the muscle gets hard and the bottom relaxes.

decreasing the angle of a joint is called flexion. this occurs many many places in the body. a specific group of muscle is responsible for this at each joint.
In performing any given movements such as bending the leg at the knee joint the muscles performing actual movement are called the prime movers or?
the nature of the word arthritis points to the bones, the words comes from Greek arthro. meaning joint, and it's referring to inflammation. These are a group of conditions inv…olving damage to the joints of the body. the condition that is known as arthritis always refers to condition that involve various degrees of pain, inflammation swelling, joint stiffness around the joint(s) of the body. Arthritic disorders like lupus and rheumatoid can also affect other organs in the body and cause muscle damage around affected joints both directly as a result of inflammation and as a result of pain leading to muscle atrophy.
