![]() ![]() The rhomboid minor is composed of the smaller muscles in the rhomboids, which connect the first upper back vertebra and the bottom neck vertebra to the shoulder blade. ![]() Treatment for a severely injured rhomboid major muscle would mean surgery, plus post-surgical physical therapy that involves a lot of activities and stretches to help improve muscle endurance. This means the range of motion of the upper extremities become limited. The dorsal scapular artery (which stems from the subclavian artery) sends oxygenated blood to the rhomboid major muscle, making it also its primary connection to the spinal column.Ī torn or injured rhomboid major muscle results to a partially debilitated scapula. It also attaches to the triangle-shaped surface at the base of the spine of the scapula - a bony structure found between the two shoulder blades, dividing them into two parts. The rhomboid major arises from the bony projections on the posterior of the vertebra - the spinous processes - located on the second, third, fourth, and fifth vertebrae. It is what connects shoulder blade to the upper back vertebrae. The rhomboid major is composed of the larger muscles in the rhomboids. The reason why the name appears plural is because it is not only made up of one muscle, but of two. The name rhomboids is derived from the word "rhombus," the shape in which the muscles in the area appear to be patterned from. Because the group of muscles is connected to the bone and you use it for moving particular joints, it is categorized as a "skeletal muscle" (other examples include triceps and biceps). ![]() The rhomboid muscles are a group of very thin muscles located in the upper back, which connect it to the shoulder blades and are innervated by dorsal scapular nerve. The connection of muscles from the lower neck to the upper back and the shoulder blades give off a shape that's similar to a Christmas tree. Rhomboids are called the "Christmas Tree" muscles. ![]()
