The shoulder girdle is responsible for which movements of the scapula?
The shoulder girdle is responsible for movements such as protraction, retraction, elevation, depression, and upward and downward rotation of the scapula.
What are the primary muscles involved in scapula depression?
The primary muscles involved in scapula depression are the lower trapezius and the latissimus dorsi.
Which movement is not associated with the scapula?
The movement of flexion and extension is not directly associated with the scapula. The scapula primarily contributes to movements such as protraction, retraction, elevation, and depression.
Why doesnt the scapula move?
The scapula is a bone that moves as part of the shoulder joint. It is involved in various movements such as rotation, elevation, depression, and retraction to ensure proper function and range of motion of the shoulder. If the scapula appears not to move, it may be due to muscle tightness, weakness, or injury affecting the function of the surrounding muscles and joints.
Type of movement trapezius produces?
stabilizes, raises, retracts, and rotates scapula; adducts scapula and elevates /depresses scapula stabilizes, raises, retracts, and rotates scapula; adducts scapula and elevates /depresses scapula
Which muscle is located between the scapula and ribcage?
The serratus anterior muscle is located between the scapula and ribcage. It has a serrated ("saw-like") appearance and is responsible for stabilizing the scapula against the ribcage during arm movements.
Which muscle protracts and depresses the scapula?
The serratus anterior muscle protracts and depresses the scapula. It originates on the upper ribs and inserts along the medial border of the scapula. This muscle is important for stabilizing the scapula during movements like pushing and reaching overhead.
What structure does the scapula move upon?
The scapula moves against the posterior aspect of the rib cage. There is also articulation of the scapula with the humerous at the glenoid fosa and with the clavical at the acromion.
Do the pectorialis major and pectoralis minor produce different movement?
Yes, the pectoralis major is responsible for movements like arm flexion and horizontal adduction of the shoulder. In contrast, the pectoralis minor is involved in stabilizing the scapula by drawing it forward and downward.
IS upward rotation of the scapula the same as lateral rotation?
No, upward rotation of the scapula refers to movement where the scapula moves upward and rotates in an upward direction around the axis. Lateral rotation, on the other hand, is the rotation of a bone around its longitudinal axis. These are two different types of movements.
What are the movements involved in the flexion and extension of the back?
The movements involved in the flexion of the back include bending forward, while the movements involved in the extension of the back include straightening or arching backward.
Names of at least six bones in the adult human body?
