Unformatted text preview: Study guide PSY 115 Neuropharm LECTURE 02 OBJECTIVES UNANSWERED: 6,10,11,15,18,20 Objectives 1.) 4 major parts of neuron a. 1.)soma (cell body)-contains nucleus, all synthetic machinery for making new proteins i. (gray matter in brain) b. 2.)axon- transmits neurochemical signal (sometimes can have myelin) i. (white matter in brain, white cuz covered with myelin) c. 3.)terminal- vesicles packaged ready to be released when signal reaches terminal through axon d. 4.)dendrites- receptors to transmit neurochemical signals 2.) Interneuron: sends signals only within its own neuron as opposed to conventional neuron which sends signals to other neurons 3.) PROTE I NS=NEUROTRANSM I TTERS 4.) ORGANELLES OF THE SOMA NUCLEUS: a. 1.) nucleus: contains DNA b. 2.)Endoplasmic Reticulum (ER): folded membranes that are important for synthesizing proteins and fats c. 3.) Ribosomes: found on the ER and are involved in synthesizing proteins d. 4.) Golgi complex: packages proteins into vesicles for transport at the terminal e. 5.)Microtubules: Transport packaged proteins to other parts of the cell f. 6.) Mitochondria: provide energy (ATP) for cell; destroy toxins and drugs6....
