Lateral cervical region
The Regio cervicalis lateralis (lateral neck region, syn. Trigonum cervicale posterius or Trigonum colli laterale ) is a paired region of the neck. It lies behind the sternocleidomastoid region and is bounded on the back by the trapezius muscle towards the neck . The lower limit is the collarbone .
Part of the lateral neck region is known as the omoclavicular trigonum (syn. Fossa supraclavicularis major ). This area is bordered laterally and towards the head by the lower abdomen of the omohyoideus muscle , towards the middle by the lateral edge of the sternocleidomastoid muscle and below by the clavicle. The fascia of this region ( fascia omoclavicularis ) divides the area into two levels. In the superficial level ( Spatium interaponeuroticum supraclaviculare ) between the superficial sheet of the cervical fascia and the fascia omoclavicularis, embedded in fatty tissue, lie the anterior subclavian nerves and the external jugular vein . In the deep layer between the omoclavicular fascia and prevertebral lamina of the cervical fascia lie the subclavian artery , superficial cervical artery and vein , subclavian trunk , phrenic nerve and part of the brachial plexus .
