1. Organization of the nervous system (CNS, PNS, SNS, ANS, parasympathetic, sympathetic, etc.) 2. Parts of a neuron 3. Types of sensory neurons 4. How are muscles and nerves similar anatomically? (hint: think of connective tissue layers, and more) 5. How many glial cells are there compared to neurons? What are some glial cells functions? 6. How does an action potential work? What is depolarization and what causes it?

1. The skeletal muscles are controlled by the autonomic nervous system. 2. What is the function of the oligodendrocytes? - Create myelin layer - Clean up cellular debris - Supply blood and nutrients - Alert the body to an infection 3. The cells that make up the nervous system are called neurons. 7. The chemical that moves from the axon of one neuron across a gap to the dendrite of another is a neurotransmitter. 8. White matter appears white due to myelin. 9. A threshold stimulus results in the creation of an action potential. 4. What ions are necessary for a nerve impulse to occur? - Carbon and sodium - Oxygen and carbon - Potassium and sodium - Hydrogen and potassium 10. Reflexes (such as the knee-jerk reflex) occur when impulses travel from the muscle to the spinal cord and then back to the muscle. 5. Gaps between the myelin sheath along an axon are called nodes of Ranvier. 11. Which cell connects neurons to blood vessels? - Astrocyte - Oligodendrocyte - Glial - Myelin
