Q1. What is the general fiber direction of rhomboid major from the vertebral column to the scapula?
- Directly anterior
- Superomedially
- Inferolaterally
- Vertically upward
Q2. Which ligament contributes to the medial origin of rhomboid major?
- Inguinal ligament
- Transverse humeral ligament
- Supraspinous ligament
- Coracoacromial ligament
Q3. Which portion of the medial scapular border receives rhomboid major?
- The medial border above the superior angle
- The lateral border beside the glenoid
- The medial border below the root of the spine
- The superior surface of the acromion
Q4. From which part of the brachial plexus does the dorsal scapular nerve usually arise?
- Lower trunk only
- Medial cord
- C5 root
- Posterior cord
Q5. Which artery commonly accompanies the dorsal scapular nerve along the medial scapular region?
- Dorsal scapular artery
- Radial artery
- Thoracoacromial artery only
- Inferior epigastric artery
Q6. How does rhomboid major cooperate with levator scapulae?
- They both protract the scapula
- They cooperate primarily in upward rotation
- They both abduct the humerus
- They cooperate in downward rotation and scapular stabilization
Q7. Which major muscle acts as an antagonist to rhomboid major during scapular protraction?
- Serratus anterior
- Rhomboid minor
- Middle trapezius
- Levator scapulae
Q8. How does rhomboid major contribute to posture of the shoulder girdle?
- It suspends the humerus from the elbow
- It flexes the cervical spine
- It helps maintain the scapula in a retracted and stable position
- It depresses the ribs during quiet breathing
Q9. Which muscle action of rhomboid major helps return the scapula from an upwardly rotated position?
- Downward rotation
- Protraction
- Humeral lateral rotation
- Upward rotation
Q10. Why is rhomboid major considered an extrinsic rather than intrinsic back muscle?
- It acts only between adjacent vertebrae
- It is supplied exclusively by posterior rami
- It belongs to the transversospinalis group
- It connects the axial skeleton to the scapula and is supplied by a brachial plexus nerve
