AB  - There  are  various  techniques  for  categorizing  the  complex  anatomy  of  the  neck.  Based  on  anatomic  boundaries,  the  neck  is  divided  into  anterior  and  posterior  triangles  and  suprahyoid  and  infrahyoid  regions.  The  boundaries  of  the  posterior  triangle  are  the  sternocleidomastoid  muscle  (SCM)  anteriorly,  the  trapezius  muscle  posteriorly,  and  the  middle  third  of  the  clavicle  inferiorly.  The  apex  of  the  posterior  triangle  is  the  point  at  which  the  sternocleidomastoid  and  trapezius  muscles  meet  at  the  occipital  bone.  The  roof  of  the  posterior  triangle  is  formed  by  the  investing  layer  of  the  cervical  fascia,  and  the  floor  consists  of  the  muscles  covered  by  the  prevertebral  layer  of  the  cervical  fascia.  The  posterior  triangle  is  further  divided  into  supraclavicular  and  occipital  triangles  by  the  inferior  belly  of  the  omohyoid  muscle.  The  occipital  triangle  contains  posterior  branches  of  the  cervical  plexus,  the  accessory  nerve,  trunks  of  the  brachial  plexus,  a  portion  of  the  external  jugular  vein,  and  cervical  lymph  nodes.  The  supraclavicular  triangle  contains  a  portion  of  the  subclavian  artery,  the  suprascapular  artery,  and  supraclavicular  lymph  nodes.
