Final answer:
The serratus anterior and rhomboids have opposing roles in scapular movement, with the serratus anterior causing abduction and the rhomboids causing adduction.
Step-by-step explanation:
Regarding the relationship between the rhomboids (both major and minor) and the serratus anterior, the accurate statement is D) The serratus anterior and rhomboids have opposing actions in scapular movement. The rhomboids, when contracted, pull the scapula medially towards the spine, which is referred to as scapular retraction or adduction. On the other hand, the serratus anterior is responsible for scapular protraction, moving the scapula laterally away from the spine, which is also known as scapular abduction. Therefore, the serratus anterior and rhomboids perform opposite movements in the context of manipulating the position of the scapula.
