1. The Latin word meaning "bark" of a tree is used for the area of the brain called the cortex.
2. The midbrain includes structures such as the superior and inferior colliculi and red nucleus.
3. A structure important for movement and balance is the cerebellum.
4. The central nervous system is divided into two major parts: the brain and the spinal cord.
5. In the central nervous system, collections of neurons are called nuclei.
6. A bump or bulge on the cortex is called a gyrus and a groove is called a sulcus.
7. One important function of the hypothalamus is to control body temperature.
8. The brain contains about 100 billion neurons and trillions of "support cells" called glia.
9. The limbic system is a group of structures that includes the amygdala, the hippocampus, mammillary bodies and cingulate gyrus.
10. In the peripheral nervous system, a collection of axons is called a nerve.
11. The brain is divided into two halves called hemispheres.
12. In the peripheral nervous system, collections of neurons are called ganglia.
13. The thalamus receives sensory information and relays this information to the cerebral cortex.
14. One part of the limbic system that is important for memory and learning is called the hippocampus_.
15. The right and left sides of the cerebral cortex are connected by a thick band of nerve fibers called the corpus callosum.
16. In the central nervous system, a collection of axons is called a tract.
