There are two rhomboid muscles on each side of the upper back: [1] [2] [3] Rhomboid major muscle; Rhomboid minor muscle; The large rhombus-shaped muscle, located under the trapezius muscle, in the upper part of the thoracic region of the back, and the small muscle, in the same way, participate in the movement of the scapula.

The erector spinae (/ ɪ ˈ r ɛ k t ər ˈ s p aɪ n i / irr-EK-tər SPY-nee) [1] or spinal erectors is a set of muscles that straighten and rotate the back. The spinal erectors work together with the glutes ( gluteus maximus , gluteus medius and gluteus minimus ) to maintain stable posture standing or sitting .
In the thoracic region, the thoracolumbar fascia consists of a single layer - an upward extension of the posterior layer of the lumbar fascia, becoming progressively thinner before fading out above the 1st rib, replaced by the splenius muscle. [3] In the thoracic region, it forms a thin fibrous fascial covering for extensor muscles associated ...
The rotatores muscles (rotatores spinae muscles) lie beneath the multifidus and are present in all spinal regions but are most prominent in the thoracic region.. Each muscle is small and somewhat quadrilateral in form; it arises from the superior and posterior part of the transverse process, and is inserted into the lower border and lateral surface of the lamina of the vertebra above, the ...
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
The rhomboid major is a skeletal muscle of the back that connects the scapula with the vertebrae of the spinal column. [1] It originates from the spinous processes of the thoracic vertebrae T2–T5 and supraspinous ligament; it inserts onto the lower portion of the medial border of the scapula. [2]
Generally, foam rollers range anywhere from 36 inches (the standard large size) for a full body roll and go down to around 6-12 inches for massaging your triceps, for instance. Medium sizes are ...
It arises by a series of small tendons from the transverse processes of the sixth to the tenth thoracic vertebrae, and is inserted, by tendons, into the spinous processes of the upper four thoracic and lower two cervical vertebrae. The semispinalis muscles are innervated by the dorsal rami of the cervical spinal nerves.
