Summary Introduction

To review:

Match the term rhomboid muscles with the most closely related description given below:

abducts the toes

flexes hip and/or lumbar spine

adduct (retract) scapula

connective tissue bands

plantar flexion at ankle

originates on ilium

flexes elbow

dorsiflexes ankle and inverts foot

lateral rotation of humerus at shoulder

supinates forearm

extends, adducts, medially rotates humerus at shoulder

Introduction:

The levator and rhomboid muscles attach to the posterior surfaces of the thoracic and cervical vertebrae. These muscles insert across the scapula’s vertebral border, between the inferior and superior angles.

Explanation of Solution

In general, rhomboid muscles are called rhomboids. These muscles are rhombus-shaped. Contracting the rhomboid retracts or adducts the scapula, thus pulling it toward the back’s center. It also rotates the scapula in the downward direction.

Conclusion

Therefore, it can be concluded that the term rhomboid muscles can be correctly matched with option (c) adduct (retract) scapula.
