# The Central Nervous System: Functional Anatomy of the Brain & Spinal Cord **Instructions:** Use the key terms to answer questions 3-6. **3. Cerebral Hemispheres:** * a. Cerebral cortex (gray matter) * b. Cerebral white matter * c. Basal nuclei **4. Ridges:** Gyri **5. Grooves (shallow):** Sulcus **6. Grooves (deep):** Fissure ## Key Words * Sulcus * Gyri * Cerebral cortex (gray matter) * Cerebral white matter * Basal Nuclei * Cerebellum ## Cerebral Cortex: Match description to term **7.** Fissure **8.** General term for nerve fiber tracts that connect the two hemispheres of the brain. **9.** General term for nerve fiber tracts that connect areas within one hemisphere. **10.** Area of cerebral cortex responsible for processing impulses traveling from the body’s sensory receptors (except for special senses). **11.** Area of the cerebral cortex responsible for voluntary skeletal muscle movements. **12.** Spatial map showing how much of the cerebrum is devoted to sensory functions. **13.** General term for nerve fiber tracts that connect the cerebrum with the brain stem. **14.** Help regulate voluntary motor activities by modifying instructions to skeletal muscles. **15.** Spatial map showing how much cerebral brain tissue is devoted to motor functions. **16.** Neuron pathway formed by neuron axons of the precentral gyrus; descends to the spinal cord. **17.** Area of the brain involved in intellectual reasoning and socially acceptable behaviors. **18.** Area of the brain at the junction of the temporal, parietal, and occipital lobes enabling speech. **19.** Large commissure connecting the left and right cerebral hemispheres. **20.** Part of the brain that recognizes patterns, faces, and inputs to understand a whole situation. **21.** Area of the brain involved in motor speech (usually one hemisphere). **22.** Composed of deep nerve fiber tracts carrying impulses to, from, or within the cerebral cortex. **Key Words Matching (continued)** * a. cerebral cortex * b. Broca's area * c. cerebral white matter * d. commissures * e. basal nuclei * f. primary somatic sensory area * g. anterior association area * h. corpus callosum * i. association fibers * j. parietal lobe * k. posterior association area * l. central sulcus * m. speech area * n. sensory homunculus * o. primary motor area * p. Pyramidal tract (corticospinal tract) * q. motor homunculus * r. projection fibers **Note:** Some items (e.g., 11, 12, etc.) in the original image were missing text. I've attempted to complete them based on context. Other portions of the original text had questionable OCR or incomprehensible phrases.
