What makes up the scapulothoracic joint?
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 articulation. 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.
The metacarpal-phalanx joint is what type of joint?
The phalanx-phalanx joint is a hinge joint.A hinge joint allows extension and retraction of an apendage.
What is the action of the levitor scapulae muscle?
Raises the scapula at the Scapulothoracic Joint or inclines neck to corresponding side if the scapula is fixed
Where is bursa found near the shoulder area?
Bursitis is a condition in which there is an inflammation of the bursa, which is a sac that is located between muscles or tendons of the shoulder. A cause of shoulder bursitis can be overuse of the shoulder joint. This condition can cause pain.
What muscles are around the pivot joint?
The muscles around the pivot joint are the Quadricep and the Hamstring muscles.
The receptors lying in joint and muscles are?
receptors lying in joint and muscles
What is the difference between core and joint muscles?
Core muscles are in your core joint muscles are in your arms and legs
Are muscles that bend a joint called extensors?
Muscles that bend a joint are flexors; musces that straighten a joint are extensors.
What are two muscles that are synergists with the biceps femoris muscle?
The semitendinosus and the semimembranosus muscles assist the biceps femoris in the action of flexing the knee joint. The semitendinosus and the semimembranosusmuscles also work together to perform extension of the hip joint.
Is a muscle makes a movement in the joint?
Opposing muscles use connective tissues to cause movement in a joint.
List of two joint muscles in upper and lower limb?
Two joint muscles in the upper limb is the wrist and the elbow. Two joint muscles in the lower limb is the ankle and the knee.
What happens to your muscles when your joint is bent?
When a joint is bent, the muscles around that joint contract and shorten. This causes the joint to move, resulting in the bending or flexing of the joint. The specific muscles involved and the degree of contraction depend on the joint and the movement being performed.
