T or F: the true spinal nerve trunk is surrounded by three meninges
True
What are the contents of the IVFs
3 meninges dorsal root ganglia spinal artery anterior and posterior radicular veins dural root sleeve (encloses kadyi) recurrent meningeal nerves intervertebral veins lymph channels adipose tissue
where do the intervertebral veins communicate?
between the internal vertebral and external vertebral venous plexus

the sup vertebral notch of the pedicles is almost completely flat as compared to inferior vertebral notch
what are the branches of the spinal artery
anterior branch
posterior branch
neurospinal artery
how does the neurospinal artery divide
anterior and poster radicular arteries
how do intervertebral veins communicate
they communicate between internal vertebral and external vertebral venous plexus
what two nervous systems help to maintain homeostasis of the body?
sympathetic and parasympathetic
what are the three layers of the meninges?
