Chapter 50, Problem 1TYK
Summary Introduction
Introduction: Skeletal system protects the body of animals from external damage, and it also helpful for movement. The skeletal system varies from animal to animals, and the types of the skeletal system are exoskeleton, endoskeleton, and hydrostatic skeleton.

- Which of the following statements about sensory systems is NOT true? a. Sensory transduction involves the conversion (by either a direct or indirect mechanism) of a physical or chemical stimulus into changes in membrane potential difference. b. Sensory adaptation plays a role in the ability of organisms to discriminate between important and unimportant information. c. The term "sensory adaptation" refers to the process by which a sensory cell becomes less sensitive, or less responsive, to a continuing source of stimulation. d. In general, a stimulus causes a change in the flow of charged ions across the plasma membrane of a sensory receptor cell. e. The more intense a stimulus is, the greater the peak depolarization of the action potentials fired by the sensory neuron.arrow_forwardWhich statement about a center-surround receptive field is false? Select one: a. It can involve an inhibitory response (e.g., to touch) b. It is characterized by a circular center and a doughnut-shaped surround c. It is found only in primary sensory cortex d. It can be mapped by electrophysiological recording techniques e. It can involve an excitatory response (e.g., to touch)arrow_forwardWhich of the following are correct? Which one or more? a. Auditory fatigue is the increase in threshold after exposure to a loud sound. Auditory adaptation is a reduction in response of the auditory receptors to a sound over time followed by a steady state. b. The change in auditory thresholds is independent of the intensity, but dependent on the duration of the loud sound. c. Exposure to loud sounds is unable to damage the hair cells in the inner ear and therefore cannot lead to a permanent threshold shift. d. Auditory adaptation is the increase in threshold after exposure to a loud sound. Auditory fatigue is a reduction in response of the auditory receptors to a sound over time followed by a steady state.arrow_forward
