During a procedure called a lumbar puncture,CSFsurrounding the meringues is withdrawn with a needle. a. This procedure generally is performed between L3 and L5.why do you think the fluid is withdrawn here rather than from higher up in the vertebral column?(hint:think about the structure and location of spinal cord b.often,the sampled CSF is tested for bacteria or virus if a brain infection is suspected.why would CSF sampled from the spinal cord give you information about the condition of the brain? c.would you withdraw CSF if the needle were accidentally inserted in to the epidural space instead of the subarachnoid space ?why or why not?

Links the retina to the brain's visual cortex; III damage causes blindness in part or all of a visual field IV c. Regulates voluntary movements of the eyelid and eyeball V VI d. Damage to sensory branch causes loss of sensation in upper face VII VIII e. Governs tongue movements, swallowing, and gagging IX f. Damage causes tongue to deviate toward injured side X XI g.
