Sectional anatomy of the neck.

Abstract: This is the first in a series of articles structured to provideanatomicallyaccuratefunctionalschematicsofthemotorandsensoryinnervation of the face, neck, and trunk. This article provides radio-graphically oriented cross sections through the neck to assist in iden-tifying clinically significant structures on diagnostic images and forinjection procedures. Future articles will present the same informa-tion for the face, chest, and abdominal regions, respectively. Key Words: stellate ganglion blocks; nerve root block; botulinum;neck pain; electromyography; neck, anatomy; cervical, anatomy;spastic torticollis; nerve root avulsion( J Comput Assist Tomogr 2004;28:295–298) T heneckandcervicalspinearefrequentsitesfortherapeuticand diagnostic injections as well as surgical interventions.An understanding of the complex anatomy of this area is criti-cally important to guide optimal placement of electromyogra-phy electrodes, for selection of locations for therapeutic injec-tions, and for presurgical planning. Procedures involvemuscles, nerves, or vessels.
