Chapter 07 - Sensory Physiology 7-1 Chapter 07 Sensory Physiology Multiple Choice Questions 1. Which of the following statements regarding sensory systems is correct? A. All sensory information that reaches the brain can be experienced as a conscious sensation B. Sensory information that leads to conscious awareness of the stimulus is called a sensation C. The term, "sensory unit," refers to a group of receptors that receive a particular stimulus and the afferent neuron associated with those receptors D. Both all sensory information that reaches the brain can be experienced as a conscious sensation and the term, "sensory unit," refers to a group of receptors that receive a particular stimulus and the afferent neuron associated with those receptors are correct E. Both sensory information that leads to conscious awareness of the stimulus is called a sensation and the term, "sensory unit," refers to a group of receptors that receive a particular stimulus and the afferent neuron associated with those receptors are correct Bloom's Level: 1. Remember Section 7A.02 Topic: Nervous System 2. A given sensory receptor A. Responds to nonspecific physical or chemical changes in its environment B. Transduces several forms of energy to electrical impulses C. Is found at the peripheral endings of efferent neurons D. Is described by all of the choices E. Is described by none of the choices Bloom's Level: 1. Remember Section 7A.01 Topic: Nervous System

Chapter 07 - Sensory Physiology 7-2 3. The receptor potential A. Is an action potential B. May trigger action potentials C. Varies in magnitude with stimulus strength D. Is both an action potential and varies in magnitude with stimulus strength E. Is both may trigger action potentials and varies in magnitude with stimulus strength Bloom's Level: 1. Remember Section 7A.01 Topic: Nervous System 4. A sensory unit is A. All of the sensory receptors in a given area of the body that respond to the same stimulus B. A single receptor ending and its afferent nerve fiber C. A single afferent neuron and all its receptor endings D. An afferent neuron and its postsynaptic interneurons E. None of the choices are correct Bloom's Level: 1. Remember Section 7A.02 Topic: Nervous System 5. The receptive field of an afferent neuron A. Refers to the number of interneurons with which the central process of the afferent neuron makes synaptic contact via divergence B. Refers to the body surface that, when stimulated by a specific stimulus, gives rise to graded potentials in the receptors of that neuron C. Is determined by the number and length of branches of the peripheral terminals of that neuron D. Both refers to the number of interneurons with which the central process of the afferent neuron makes synaptic contact via divergence and is determined by the number and length of branches of the peripheral terminals of that neuron are correct E. Both refers to the body surface that, when stimulated by a specific stimulus, gives rise to
