accessory
A loss or weakness of both __________ head rotation and ipsilateral shoulder __________ is consistent with a lesion of the accessory nerve.
contralateral, elevation
The platysma muscle is innervated by the __________ branch of the __________ nerve.
cervical, facial
The superior and inferior labial arteries are both direct branches of the __________.
facial artery

anterior scalene
The __________ reflex tests the sensory function of the Vth cranial nerve and the motor function of the VIIth cranial nerve.
corneal (blink)
The __________ traverse the transverse foramina of the cervical vertebrae.
vertebral artery (& vein)
The __________ muscle extends from the spinous process of the axis to the occipital bone and is innervated by a branch of dorsal ramus __________.
rectus capitis posterior major, C1
The __________ lymph nodes are typically positioned adjacent to the internal jugular vein.
deep cervical
The __________ muscle receives its motor innervation from the temporal and zygomatic branches of the facial nerve.
