List one way in which the conus medullaris and filum terminale are similar: List one way in which they are different: List one way in which the frontal eye field and Broca\'s area are similar: List one way in which they are different: When a spinal tap is performed on a patient, a needle is inserted below the second lumbar vertebra to remove a sample of spinal fluid. Why is the needle not inserted above this level? which type of nerve fiber (sensory or motor) travels through each of the following structures? a, anterior gray horn b. posterior gray horn c. lateral gray horn d. lateral corticospinal tract Posterior spinocerebellar tract Put the following events describing the flow of cerebrospinal fluid in order by writing the correct numeral (1-8) in the blanks. CSF enters the subarachnoid space. CSF travels down the cerebral aqueduct. CSF passes through the interventricular foramina. CSF enters the fourth ventricle. CSF passes through the two lateral and one median apertures CSF is released by ependymal cells. CSF enters the third ventricle. CSF enters the superior sagittal sinus.
4 filum terminal is the continuation of the parameter inferior to the conus medullaris. Conus medullaris is the bottom of the solid form that ends around L1 and starts to be in cone shape. Fylum terminal is connective tissue that helps anchor spinalcord to coccyx.
5. Broca\'s area is the region in the frontal lobe of the dominant hemisphere that is left hemisphere of the how many brain with functions linked to speech. The frontal eye field is an area of the frontal cortex which is able to Trigger eye movements. These two are special motor cortices .areas which allow us to act upon certain sensation
6. The spinal cord extends from the lower part of the brain down the upper lumber area lumbar puncture is done in the lowest region below the point where spinal cordt and so the risk of having spinal cord is avoided.
