Which of the following muscles is MOST directly responsible for protraction of the scapula?
Which of the following muscles is MOST directly responsible for protraction of the scapula?
- Rhomboid major
- Levator scapula
- Serratus anterior (correct)
- Trapezius (middle fibers)
The primary function of scapular depression is achieved solely by the lower fibers of the trapezius muscle.
The primary function of scapular depression is achieved solely by the lower fibers of the trapezius muscle.
False (B)
Describe the functional importance of scapular upward rotation and provide a specific example of an activity that relies heavily on this movement.
Describe the functional importance of scapular upward rotation and provide a specific example of an activity that relies heavily on this movement.
Scapular upward rotation is crucial for orienting the glenoid fossa upwards, allowing for full abduction and flexion of the humerus. An overhead press is a prime example.
During scapular retraction, the scapula moves toward the vertebral column due to the combined actions of the rhomboid major, rhomboid minor, and the ______ part of the trapezius.
During scapular retraction, the scapula moves toward the vertebral column due to the combined actions of the rhomboid major, rhomboid minor, and the ______ part of the trapezius.

What is the effect of anterior tilting of the scapula?
External rotation of the scapula refers to the same movement as lateral rotation of the scapula.
External rotation of the scapula refers to the same movement as lateral rotation of the scapula.
Describe how internal rotation of the scapula contributes to its overall function, particularly during protraction.
Describe how internal rotation of the scapula contributes to its overall function, particularly during protraction.
Downward rotation of the scapula, which involves returning the glenoid fossa to its original position, is primarily facilitated by the rhomboids and the ______ scapula.
Downward rotation of the scapula, which involves returning the glenoid fossa to its original position, is primarily facilitated by the rhomboids and the ______ scapula.
