Question 23

origin and insertion of the serratus anterior?

Answer 23

Question 24

What is “Winged scapula”?

Answer 24

In a patient with a winged scapula, the medial or lateral aspect of the scapula appears to be protruding from the back. The ranges of motion that are typically abnormal are abduction and flexion of the affected upper extremity.

The most common etiology of a winged scapula is usually due to damage or impaired innervation to the serratus anterior muscle. The nerve that innervates this muscle is the long thoracic nerve. Sometimes, this nerve can be damaged or impinged, leading to malfunction of the serratus anterior muscle.

Answer 29

origin-spinous process from the upper to mid-region of thoracic vertebrae
insertion-medial border of the scapula

Question 30

what happens to rhomboid muscles as the person gets older?
