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?
Nervous System Part A Nervous Tissue Learning about Nervous Tissue 1 Matching anatomy of the neuron: a Region that connects axon to the initial segment b Receives incoming impulses c Contains genetic material d Cell body e Contains vesicles with neurotransmitter chemicals f Interruption in a myelin sheath, leaving axon exposed g Process that carries "outgoing" impulses h Branching at the end of the axon i Phospholipids insulating axons of some neurons j Branch of axon, usually at a right angle to the axon k Dark staining granules in soma 1. Collateral 2. Nucleus 3. Node of Ranvier (myelin sheath gap) 4. Axon hillock 5. Terminal arborizations 6. Dendrite 7. Soma 8. Myelin 9. Terminal bouton (axon terminal) 10. Axon 11. Nissl bodies 2 Using the word bank listed above, draw a myelinated multipolar neuron and label all the parts listed.
