Vertebral Artery/Miscellaneous Cervical Flashcards
which side of the vertebral artery is larger
left vertebral artery is larger
gender bias regarding size of the vertebral artery
M: larger than W
name of the physical exam used to determine vertebral artery patency
vertebrobasilar artery insufficiency test
side artery was tested during the course of the vertebrobasilar artery insufficiency exam
ipsilateral artery on side of rotation
symptoms of failure of the vertebral artery to compensate during the vertebrobasilar artery insufficiency exam
dizziness, vertigo, nausea are common complaints
vertebral artery is typically a branch of which artery
subclavian artery
typically, at what vertebral level will the vertebral artery 1st become located in the transverse foramen
C6
location the vertebral artery will form its 1st compensatory loop
atlanto-axial interspace
location the vertebral artery will its 2nd compensatory loop
atlanto-occipital interspace
segments the vertebral artery will be firmly attached to the transverse foramen
C1 and C2
purpose of the vertebral artery loops between C2, C1 and occiput
increased length will accommodate the greater rotation at these locations
what forms the boundaries for the exit of C1 nerve from the spinal canal
occipital condyle superior articular process of C1 capsular ligament arcuate rim groove for the vertebral artery posterior atlanto-occipital ligament
forms the ANTERIOR boundary for C2 nerve exit from the spinal canal
inferior articular process of C1
superior articular process of C2
capsular ligament
forms the POSTERIOR boundary for C2 nerve exit from the spinal canal
posterior arch of C1
lamina of C2
posterior atlanto-axial ligament
forms ANTERIOR boundary for C3-7 nerve exit from the spinal canal
vertebral bodies intervertebral disc posterior longitudinal ligament uncinate process lateral groove
