SECTION 4: The Brain A. The brain consists of four major parts: the cerebrum, the cerebellum, the diencephalon, and the brain stem. The largest portion is the cerebrum, which has centers for sensory, motor, and cognitive functions such as memory, reasoning, and judgment. The cerebellum includes centers that coordinate voluntary muscular movement. The diencephalon consists mainly of the thalamus and hypothalamus. The thalamus processes sensory information; the hypo- the midbrain, pons, and medulla oblongata. The brainstem contains pathways that inter- thalamus is involved in regulating many aspects of homeostasis. The brainstem consists of Label the structures of the brain in Figure 13.5.
