DIFFICULTY: EasyExcitatory and inhibitory postsynaptic potentials share the following characteristic:A. Sodium channels along the cell membrane open.B. Potassium channels along the cell membrane open.C. Chloride channels along the cell membrane open.PSYC 326 Behavioral Neuroscience Fall 2011 Page 3D. They are initiated by the release of neurotransmitter by the terminal button of the presynaptic cell.Answer: D, “Postsynaptic Potentials” in Chapter 2: Structure and Functions of Cells of the Nervous System, pages 59-60.2. DIFFICULTY: IntermediateHow do the mechanisms of action differ between steroid and peptide hormones?A. Steroid hormones are released by endocrine glands while peptide hormones are secreted by neurons.B. Peptide hormones interact with the cell via secondary messengers, while steroid hormones can easily pass through the membrane and attach to nucleus receptors.C. Peptide hormones affect target cells while steroid hormones affect body fluids.D. Terminal buttons have been found to involve peptide, but not steroid receptors.Answer: B, “Nonsynaptic Chemical Communication” in Chapter 2: Structure and Function of Cells of the NervousSystem, page 65.3.
