HUBS1416 – PASS Topic 2 - Introduction to the Nervous System Welcome to PASS session 2! This is a relaxed, safe, mutual study environment. Feel free to bring lunch, snacks, coffee - whatever you need. 1 hour of PASS can be as productive as 3 hours of individual study time. There are no silly questions. If you’re unsure about something, ask! No judgment here. Sessions are voluntary and casual. Just come when you can. Please complete the sign in sheet each week that you attend. Feel free to email me if you have questions - [email protected] Time to review the nervous system! 1. The central nervous system (CNS) includes the ________ and _____________. 2. The peripheral nervous system (PNS) is made up of _______________ and ___________________. 3. Draw and label a picture outlining the key parts of a neuron:  4. Glial Cells of the CNS Cell Astrocyte Oligodendrocyte Ependymal Microglia Functions: 5. Glial Cells of the PNS Cell Schwann Cell Satellite Cell Functions: 6. What is meant by membrane potential? (hint - be sure that you’re clear about the roles of sodium and potassium in membrane potential) 7. Explain the process of depolarisation in a neuron: 8. Now explain how repolarisation is achieved in a neuron: 9. Myelinated axons conduct their action potentials much faster than unmyelinated ones. Why is this? 10. Explain what synaptic transmission is (a diagram would be great!):  11. Draw a simple tree diagram that outlines the different divisions of the nervous system: 12. What is meant by afferent and efferent? Extra tips for effective study! - Keep an eye on the learning outcomes - are you able to explain each learning outcome to a friend or family member? Try a “traffic light” system and highlight any outcomes you’re confident with in green, any you’re iffy about yellow, and ones which need the most revision red. - If you haven’t already, start a collection of flash cards. Write down any new terminology, concepts etc to add to the pile, and flick through the cards a few times a week.
