The inferior or lower (or ascending) fibers of the trapezius arise from the spinous processes of the remaining thoracic vertebrae (T4–T12). From this origin, they proceed upward and laterally to converge near the scapula and end in an aponeurosis , which glides over the smooth triangular surface on the medial end of the spine, to be inserted ...
Middle and inferior fibres of trapezius muscle, and deltoid muscle, attached to the deltoid tubercle. [ 1 ] [ 2 ] The deltoid tubercle marks the beginning of attachment of deltoid muscle. [ 1 ]
Serratus anterior forms part of the latter group together with rhomboid major, rhomboid minor, levator scapulae, and trapezius. The trapezius evolved separately, but the other three muscles in this group evolved from the first eight or ten ribs and the transverse processes of the cervical vertebrae (homologous to the ribs). [7]
Pectoralis minor, an inferior, smaller muscle to the pectoralis major; Sternalis, an accessory muscle found in some individuals that may have embryonic origin from the pectoralis major; Tra Telligman, a retired American mixed martial artist and boxer having only one pectoral muscle

Stretching from the spine to the scapula, rhomboid major forms part of the latter group together with rhomboid minor, serratus anterior, levator scapulae, and trapezius. The trapezius has evolved separately, but the other muscles in this group evolved from the first eight or ten ribs and the transverse processes of the cervical vertebrae ...
Levator scapulae forms part of the latter group together with rhomboid major, rhomboid minor, serratus anterior, and trapezius. The trapezius evolved separately, but the other three muscles in this group evolved from the first eight or ten ribs and the transverse processes of the cervical vertebrae (homologous to the ribs).
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. [4] Their functions are the following: [1] [2] [3] Drawing scapula superomedially; Supporting scapula; Rotating glenoid cavity inferiorly
