Both tend to center over the suboccipital region and radiate, to various extents, to the occiput, auricular region, vertex of the head, forehead, and orbit. In the head, pain from C1-2 tends to occur higher than pain from C2-3, in the vertex rather than in the forehead and temple.
The lower limit between the neck and thorax (cervicotoracic limit) is represented in the anterior by upper edge of sternal manumbrium (manumbrium sternum), sternoclavicular joint and clavicle (collarbone) and in the posterior by a conventional line that connects the two acromio-clavicular joints (articulatio sternoclavicularis) and the top of sp...
