Superficial Cervical Artery, Posterior View

Description

Posterior cervical and upper thoracic anatomy is rendered with the superficial cervical artery coursing across the lateral neck toward the superior shoulder girdle. Superficial muscle planes, including trapezius overlying the levator scapulae and splenius capitis, frame the vessel as it runs lateral to the cervical spinous processes and medial to the acromial region. Inferiorly, the superior angle and spine of the scapula and adjacent ribs provide bony context for the vessel’s relationship to the scapular attachments of trapezius and deltoid. Muscle fiber direction is clearly indicated. A posterior perspective on the superficial cervical artery helps clarify its typical association with the transverse cervical system (often via the thyrocervical trunk) and its variable anastomoses around the scapular region. Surgeons working in the posterior triangle of the neck or along the superior border of the scapula benefit from seeing where this vessel can be encountered during lymph node biopsy, posterior cervical flap elevation, or exposure near the spinal accessory nerve as it traverses the deep surface of trapezius. Variation is common. This layout supports teaching why unexpected bleeding can occur when dissecting between trapezius and deeper posterior neck muscles. Ideal applications include gross anatomy lab instruction on posterior neck dissection, operative anatomy figures for head and neck or shoulder approaches, and atlas plates explaining transverse cervical and scapular collateral circulation. It also fits radiology and ultrasound teaching sets that correlate surface landmarks over the trapezius with underlying arterial pathways near the supraclavicular fossa and superior scapula.
