Following dissection of the more superficial back muscles, reflect the
rhomboideus major and minor muscles (video) to expose the
serratus posterior superior muscle, levator scapula muscle, and underlying nerves and blood supply
as shown in dissection 1 and dissection 2. NOTE: The deep branch of the transverse cervical artery is called the dorsal scapular a. if
it branches directly off the axillary artery. This artery and the accompanying dorsal scapular
n. are found deep to the rhomboideus muscles about one finger's breadth medial to the scapular
border.
