Moreover, the landmarks in zone 3 start from the angle of the mandible to base of skull and also house eminent structures like the internal carotid artery, vertebral artery, external carotid artery, jugular veins, prevertebral venous plexus, and facial nerve trunk [3, 8, 9, 14, 25, 27, 28].
The phrenic nerve (C3-C5) and brachial plexus lie deep to the prevertebral fascia, thus local anesthetic administration after a brachial plexus block can result in medication "spilling" over onto the phrenic nerve.
