DRAW IT The reflex that pulls your hand away when you prickyour finger on a sharp object relies on a neuronal circuit withtwo synapses in the spinal cord. (a) Using a circle to represent across section of the spinal cord, draw the circuit. Label the typesof neurons, the direction of information flow in each, and thelocations of synapses. (b) Draw a simple diagram of the brainindicating where pain would eventually be perceived.
Which specific area of the brain may be impaired if you cannottell the difference between a smooth and a rough surface usingyour hands only?
Your friend’s cerebral blood vessel burst on account of high blood pressure and a high platelet count. After a few weeks of rehabilitation he can neither feel his fingers nor can he walk easily. Will this lack of sensation and motor abilities ever go away
