The serratus posterior superior muscle arises by an aponeurosis from the lower part of the nuchal ligament, from the spinous processes of C7, T1, T2, and sometimes T3, and from the supraspinal ligament. [2] It is inserted, by four fleshy digitations into the upper borders of the second, third, fourth, and fifth ribs past the angle of the rib. [2]
The rhomboid muscles (/ ˈ r ɒ m b ɔɪ d /), often simply called the rhomboids, are rhombus-shaped muscles associated with the scapula. There are two rhomboid muscles on each side of the upper back: [ 1 ] [ 2 ] [ 3 ]
The serratus posterior inferior and serratus posterior superior are innervated by the ventral primary ramus and are hypaxial muscles. Epaxial muscles include other (dorsal) muscles associated with the vertebrae, ribs, and base of the skull.
serratus posterior inferior: Torso, Chest vertebrae T11 – L3: inferior borders of 9th through 12th ribs: intercostal arteries: intercostal nerves: depresses lower ribs(IX to XII), aiding in expiration: 2 1 serratus posterior superior: Torso, Chest nuchal ligament (or ligamentum nuchae) and spinous processes of vertebrae C7 through T3
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]
Apart from the above neck muscles, the following muscles have also been observed contributing to respiration: serratus anterior, pectoralis major and pectoralis minor, trapezius, latissimus dorsi, erector spinae, iliocostalis, quadratus lumborum, serratus posterior superior, serratus posterior inferior, levatores costarum, transversus thoracis ...
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 ...
