Anatomy Didactic week 1 Questions and answers
1. what separates the su-
thoracolumbar fascia
perficial and intermediate
back? (intermediate =
ser- ratus posterior)
2. ventral roots
have... dorsal roots only
have... efferent
only
3. label parts of C1 that are afferent
important
posterior arch = lower on picture, where
spinous process would be
anterior arch = anterior to dens of C2
lateral masses with superior articular
facets
cervical all also have transverse foramina
for vertebral artery and vein
4. what holds the dens in
place? prevents
posterior displacement
the transverse ligament of the atlas
(goes from C1 lateral mass to C1
occipital condyles)
5. what checks excess
rota- tion of the head
AAJ, the alar ligaments attach to each side
of dens (go from dens to occipital bone)
