Musculus rhomboideus cervicis
Connects the cervical spine to the scapula, helping to elevate and stabilize the shoulder blade. Part of the extrinsic forelimb musculature that forms the muscular sling suspending the thorax between the forelimbs.
Origin: Funicular part of the nuchal ligament (over cervical vertebrae C2-C5)
Insertion: Medial surface of the scapular cartilage
Action: Elevates and retracts the scapula; supports the trunk between the forelimbs
Innervation: Ventral branches of cervical spinal nerves (C4-C6)
Weakness or dysfunction of the rhomboideus contributes to poor scapular stability and affects forelimb movement quality.
Weakness or dysfunction of the rhomboideus contributes to poor scapular stability and affects forelimb movement quality. Signs include: Winging of the scapula during movement; uneven shoulder height; reduced forelimb reach; difficulty maintaining consistent contact.
