Fig. 6From: Ultrasound-guided regional anesthesia simulation: use of meat glue in inexpensive and realistic nerve block modelsIncision in red indicates the location of the carotid artery (a). Thin layer of meat covering the model simulates the sternocleidomastoid muscle (b). SCM, sternocleidomastoid muscle; AS, anterior scalene muscle; MS, middle scalene muscle; CA, carotid artery; the interscalene brachial plexus is located between AS and MS muscles; 1, C5 nerve root; 2, C6 nerve root; 3, C7 nerve rootBack to article page
