Document Summary
Ch 7 slide titles, part 1: sensing the environment, sensory perception depends on properties of receptors, figure 7-1. Clicker question: in sensory phys, adaptation is defined as a decrease in the response of a receptor or sensory neuron with time, despite the presence of a stimulus that is unchanging in amplitude. ** the echolocation sense uses all of the following common structures to the vertebrate ear, except: modified neuron receptor** Organ of corti is the little space sitting on top of the basilar membrane. Receptors can be sensitive to light energy, changes in the shape of the membrane, or chemicals. Stimulus to be sensed, there must be a receptor/receptor structure. The job of the receptor is to detect and amplify. Neural transmitters have to be released for the signal to get to the. Amplification isn"t always large enough to send to cns: receptor types (slide provided) Chemoreceptor: chemical signals; gustation and smell (overall taste)
