The medial attachments of the rhomboid major muscle are specifically found on the spinous processes of the T2 to T5 vertebrae. This anatomical feature is crucial for understanding the muscle's function and its role in movement. The rhomboid major, alongside the rhomboid minor, helps retract the scapula, pulling it toward the spine. The attachment to the spinous processes means that when the muscle contracts, it effectively pulls the scapula in a medial direction, which is essential for stabilizing the shoulder girdle and assisting with upper limb movements.

The other options do not accurately describe the medial attachments of rhomboid major. For instance, the occipital ridge pertains to the attachment of muscles involved in head and neck movements, but it is not related to the rhomboids. The transverse processes of the cervical vertebrae, like C1-C6, indicate a different muscle group, primarily those involved in neck stability and movement. Lastly, the nuchal ligament serves as an attachment for muscles in the upper back and neck area, but it does not connect to the rhomboid major's function or structure. Understanding the specific attachment points helps clarify how the muscle operates within the anatomy of the back and shoulder region.
