Answers,

the sympathetic outflow is thoraco lumbar outflow and parasympathetic is craniosacral . so the the sympathetic should be through the blood vessels. Please correct me if I am wrong.Thnks

The MOST susceptibble sites in the nervous sysem for the effects fo acute ischemic anoxia are
1- motor end plate
2- sensory receptors
3- synapses in autonomic ganglia
4- synapses in central nervous system

I guess the answer should be 4 - for the reason that cns comprising brain and spinal cord - especially the brain cant with stand hypoxia and it is more susceptible to ischemia. Please help!
