Be sure that you’re accessing the 4th edition of the textbook. To maintain Academic Integrity and maximize your learning , each response needs to be in complete sentence form and in your own words - copying/pasting from the textbook or another source could result in negative consequences. **Note- questions that are in BOLD are frequently tested concepts on the AP Exam Section 2.01 The Neuron: The Building Blocks Pages 52-56 1. Explain the function for each part of the neuron: Read pgs 54-56 for this question Axon: Long tube like structure it sends neural messages from soma to axon terminals. Part of the neuron that allows communication with other cells Axon Terminal: located at ends of branches of axon, responsible for communication with other cells Cell Body: called some, holds vital parts of cell. Holds nucleus, DNA, mitochondria and vitals Dendrite: gets signals from cells and named for branch like structure Myelin sheath: protective covering of fatty tissue that blocks the axon of neurons. Speeds up transmission of messages insulates neuron produced by certain glial cells Pg. 55 2. Summarize the various roles Glial Cells Can take roles, some glial cells act as structure neurons develop and work to hold neurons in place. Glial involved getting nutrients to neurons,

have in brain functioning and development. communicating with neurons and other glial cells, cleaning up neurons dead, provide insulations for neurons. 3. What is the connection between the myelin sheath and multiple sclerosis? If patient has multiple sclerosis myelin’s health affected neurons destroyed leads to loss when comes to neural functioning in damaged cells. Optional Notes Section: N/A Section 2.02 The Neurotransmitter & Psychoactive Drugs: The Instant Messenger of the Brain Pages 56-63 4. A.What is meant by semipermeable when describing the membrane of the axon? B. Which two ions are “allowed”? A. Axon membrane semipermeable meaning substances outside of cell enter through tiny protein openings in membrane. B. Channels are gated meaning only opening and close based electrical potential of membrane 5. Explain resting potential . When neuron isn’t firing neural impulses, simply hanging out in our bodies not sending signals 6. Explain what is happening during Action Potential. Be specific. The neuron releases a neural impulse consisting of reversal of electrical charge with the axon, allows positive sodium ions to enter cell.

Pg. 58 7. What happens in the axon after the impulse has passed? **Also known as the Refractory Period** Axon needs to repolarize self and axon is in depolarization state. Axon needs to return to resisting potential in order to fire other impulse, amount of time taken for axon to be ready for second stimulus called refractory period.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
