PSY 102: Psychology in the Modern World Your Name: Bhargav Patel Instructor: Bob Melara Your Section: C4 Fall 2010 Your TA’s Name: Greta Petro Homework #2 (Neuroscience and Behavior) 1. a) What are the parts of a neuron? b) How are neural impulses generated? c) How does one nerve cell communicate with another? The neuron consists of the Dendrites, Cell body, Axon, Neural impulse, Terminal branches of axon, and the Myelin sheath. A neuron fires a brief electrical pulse called the action potential. When an action potential reaches the terminal branches of the sending neuron it sends vesicles containing neurotransmitters. They are then released into the synapse and then bind to the receptor sites on the receiving neuron. 2. a) Explain what neurotransmitters are? b) What is an agonist? c) What is an antagonist? Neurotransmitters cross the synapse which triggers action potential. An agonist binds to a receptor of a cell and triggers a response by the cell. An antagonist acts against blocks an action.

    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.
