Document Summary

Nervous system: communication general principles of sensory physiology identify the general path of sensory information flow from the peripheral nervous system to the central nervous system. Stimulus sensory receptors afferent neuron- interneuron . Distinguish between sensory information, sensation, and perception. Sensory information: information that originates in stimulated sensory receptors. Sensation: the mental perception of a stimulus. Perception: understanding of objects and events of the external world that we acquire from neural processing of sensory information. Describe the function of sensory receptors; appreciate that receptors can be a. Define adequate stimulus, sensory unit, and receptive field. Adequate stimulus: the modality of stimulus to which a particular sensory receptor is most sensitive. Sensory unit: smallest unit of sensory perception, 1 afferent neuron and all its receptor endings. Receptive field: the are served by the receptor density list the five types of sensory receptors and their adequate stimuli. Mechanoreceptors: touch, pressure, vestibular, hearing, internal bones, proprio-neurons.
