(Circle the appropriate response or responses.)  cerebral hemispheres  pons  midbrain  cerebellum  medulla oblongata  diencephalon

4. Complete the following statements by writing the proper word or phrase on the corresponding blanks at the right. A(n) 1 is an elevated ridge of cerebral tissue. The convolutions seen in the cerebrum are important because they increase the 2 . Gray matter is composed of . 3 White matter is composed of . 4 A fiber tract that provides for communication between different parts of the same cerebral hemisphere is called a(n) 5 tract, whereas one that carries impulses from the cerebrum to lower CNS areas is called a(n) 6 tract. The caudate nucleus, putamen, and globus pallidus are collectively called the 7 . 1. gyrus 2. Surface area 3. Neuron cell bodies 4. Myelinated fibers 5. Association tract 6. Projection 7. Basal nuclei 5.
