Introduction:
Structures that are specialized for the detection of a stimulus, such as pain and heat, are referred to as a sensory receptor. Such receptors can either be real sense organs or simple nerve endings. Sense organs, much complex structures containing receptors, combines with other tissues, such as muscular, epithelial and connective tissues, and with nervous tissues. The nervous tissues enhances the response of the sense organs to a particular kind of stimulus. Sense organs are involved in the transmission of data (through neurons) to the specific place inside the nervous system. Such sense organs may range from simple microscopic structures, like dendrites, to complex structures, like ear and eye.

- Awareness of a stimulus is called a ________.arrow_forwardLarry goes to the doctor complaining that he cant see the right side of the visual field with either eye. Where in the visual signal-processing pathway is Larrys problem occurring?arrow_forwardDescribe the flow of generation of receptor potential when sensory receptors detected stimuli.arrow_forward
- Some somatic senses are fast-adapting and others are slow-adapting. Two different types of receptors are listed below. Explain the advantage using an example, for it to be slow or fast. Then explain, using an example, for why it would be harmful if it was the opposite type.  Temperature receptor for cold temperatures, fast-adapting    2.Muscle-spindle proprioceptor, slow-adaptingarrow_forwardIn general, could we name the sensory receptors “middle men” between the stimulus and the peripheral nervous system? Please shortly explain your answer.arrow_forwardDefine accommodation (aka adaptation) of receptors and give two examples of such.arrow_forward
- We discussed three principles with regards to the sensory cortex (mechanisms of perception), with one of them being a hierarchical organization. Using the somatosensory system as an example (specifically the exteroceptive part of that system), state each level of the hierarchy with regards to this system, beginning with the one at the lowest level of the hierarchy to the final uppermost level. give the name at each level as it corresponds with this system.arrow_forwardIf all neurons transmit the same type of message, how do you know the difference between sound and light? How are you able to distinguish between an intense pain and a mild one? How are these discriminationsadaptive?arrow_forwardIn the process of sensory coding   Recruitment of additional neurons occurs with a weak stimulus in order to make the stimulus stronger.  The larger the receptive field of a sensory receptor, the greater the expected acuity and the more accurate the two-point discrimination.  Lateral inhibition of neighboring receptors resulting in a relative reduction of action potentials in the neighboring second order neurons would be expected to increase acuity.  A receptor potential that remains suprathreshold into the absolute refractory period will result in additional action potentials.arrow_forward
