2The neck is a biomechanical wonder! Connects the head to the trunkConduit for blood vessels, nerves, and hollow organsAll of these complicated structures are packed in a very narrow area that allows for a great deal of mobility for the head as it moves relative to the ground
20SVC Syndrome Occlusion of the SVC causes engorgement of the superficial veins that drain the headand neck (usually due to cancer)
21Practical Application of Anatomy! A little pressure to thecervical plexus and...VOILA!Practical Application of Anatomy!
22Deep Cervical Fascia Form the boundaries of compartments Fascial spaces can communicate infection or fluid to other regions of the bodyUsed as a guide to surgical dissectionAllow the neck structures to glide past one anotherSupports the thyroid, lymph nodes and blood vessels
25Deep Cervical Fascial Spaces Retropharyngeal - b/n prevertebral and buccopharyngealPretracheal - b/n infrahyoids and tracheaLateral pharyngeal - lat to pharynx and communicate with RP and SM spacesSubmandibular - below tonguedeep portion above mylohyoidsuperficial portion below mylohyoid
