But as neither the cervical or dorsal insertions of the sjilenius are exposed, it is necessary to proceed to the second part of the operation by removing the rhomboideus, angularis, and the superior extremity of the shoulder. To prepare the third layer, which com- prises the great and small complexus, it is sufficient to excise the splenius, in following the direction of the neck, and to turn upwards and downwards the two portions of the muscle (^See fig. 100). Lastly, the deep layer—the transverse spinous, intertransverse, oblique, and jDosterior straight muscles, as well as the cervical ligament—is exposed by removing the two complexus and the ilio-spiualis muscles (See fig. 104). 1. Bhomhoideus. (Figs. 101, 6; 104, 1, 2.) Synonyms.—Described by Bourgelat as two muscles, the proper elevator of the shoulder and the rhomboideus, these were termed by Girard the cervico-subscapularis and dorso-subscapularia. (This is the rhomboideus longus and brevis of Percivall, and the dorso-scapularis and cervico-subscapularis of Leyh.) Form—Situation—Direction.—This muscle has the form of a very elongated triangle, and is situated at the inner as2:)ect of the cervical trapezius and the scapular cartilage, beneath the cervical ligament, whose direction it follows.
