A) Merkel's disks B) Pacinian corpuscles C) Meissner's corpuscles D) Krause end bulbs 2. What is meant by the notion “the output of the cortex can influence the input of the cortex”? Choose the correct option. A) Neurons of the thalamus and dorsal column are controlled by the cortex B) Information is transferred unchanged through the brain stem and the thalamus C) Information synapses at the thalamus before proceeding to the neocortex D) Somatic sensory system of a side of the brain is related to the other side of the body 3.

Test 08 Page 2 of 5 Question 6: Imagine rubbing your finger across a pane of smooth glass and then across a brick. What kinds of skin receptors help you distinguish the two surfaces? As far as your somatic sensory system is concerned, what is different about the two surfaces? Question 7: What purpose is served by the encapsulations around some sensory nerve endings in the skin? Question 8: If someone tossed you a hot potato and you caught it, which information would reach your CNS first — news that the potato was hot or that it was relatively smooth? Why? Question 9: At what levels of the nervous system are all types of somatic sensory information represented on the contralateral side: the spinal cord, the medulla, the pons, the midbrain, the thalamus, the cortex? Question 10: What lobe of the cortex contains the main somatic sensory areas? Where are
