Item 1 Part A The hypothalamus is the area where afferent impulses from all senses and all parts of the body are sorted out and then relayed to the appropriate area of the sensory cortex. True False Submit My Answers Give Up Correct Afferent impulses from all senses and all parts of the body converge on the thalamus (not the hypothalamus) and synapse with at least one of its nuclei. The thalamus--which sorts out and "edits" these afferent signals before relaying them to the appropriate cortical areas--is considered to be the gateway to the cerebral cortex. B Item 2 Part A Which of the following is true of the cerebral hemispheres of the human brain? Nearly the entire surface of the cerebral hemispheres is marked by elevated ridges called sulci. The longitudinal fissure separates the cerebral hemispheres from the cerebellum. Nearly the entire surface of the cerebral hemispheres is marked by shallow grooves called gyri. The cerebral hemispheres account for about 83% of total brain mass. Submit My Answers Give Up Correct The cerebral hemispheres, which form the superior part of the brain, account for about 83% of total brain mass. D Item 3 Part A Which of the following describes the nerve fibers indicated by the letter A? first-order sensory neurons second-order sensory neurons third-order sensory neurons Submit My Answers Give Up Correct First-order sensory neurons transmit sensory information from receptors to the spinal cord. A Item 4 Part A During meningitis, which of the following is the most likely to be a direct source of pathogens that may spread to the brain? pia mater arachnoid mater dura mater arachnoid villi Submit My Answers Give Up Correct The pia mater is meningeal layer closest to the brain. A Item 5 Part A What is the designation of the area at D? primary visual cortex multimodal association area visual association area primary olfactory cortex Submit My Answers Give Up Correct The primary visual cortex receives sensory input from the eye via the optic nerves, thalamus, and optic radiations. A Item 6 Item 7 Part A Where are the cell bodies of the sensory neurons at A located? in the dorsal root ganglion in the medulla oblongata in the posterior horn of the spinal cord in the thalamus Submit My Answers Give Up Correct All sensory neurons, including those of the autonomic nervous system, are found in the dorsal root ganglion. A Item 8 Part A Which part of the brain is the "executive suite" that controls almost all brain activity? cerebellum cerebral cortex diencephalon brain stem Submit My Answers Give Up Correct The cerebral cortex is the "executive suite" of the nervous system, where most of our higher-level decision making occurs. It enables us to be aware of ourselves and our sensations, communicate, remember, understand, and initiate voluntary movements. B Item 9 Part A In general, a primary sensory cortex breaks down sensory input into component parts, while an association cortex makes sense of sensory inputs. True False Submit My Answers Give Up Correct
