Psy 251 Miami University exam 2 questions with correct answers

Sensory receptors Answer -Receptors convert stimuli in the environment into generator potential on sensory neuron -Sensory Neurons can be part of receptor or synapse on the receptor - different types of receptors are particularly sensitive to different, specific stimuli receptors cont. Answer -they can be free nerve endings on sensory nerves - receptors are sensitive to tissue damage and initiate sensation of pain via graded membrane potential charge -they can be specialized, independent cells that synapse of sensory nerves -receptors respond to stimulus with graded EPSP or graded IPSP EPSP Answer excitatory postsynaptic potential voltage change approaches threshold making an AP more likely depolarization usually a result of opening a Na+ channel IPSP Answer Inhibitory postsynaptic potential voltage change away from threshold making an AP less likely hyperpolarization making it more negative
