Describe three features of sensory
processing that occur at the receptor level where a
sensation is first detected. How is information about the stimulus
coded before it is passed into the
CNS?
In the concept of sensory physiology, please describe the
following:
What is a sensory receptor? What is its function and
structure?
Describe the generation of a “receptor potential” and explain
the differences between a receptor potential and an action
potential
What is the mechanism of adaptation in a sensory receptor?
Classify and describe the sensory receptors depending on their
adaptation abilities.
1.
After a receptor signals a sensory neuron in a reflex what happens?
2. Examples of Exteroreceptors would be?
3. A cerebral cortical area NOT associated with a special
sense is?
4. What is a tactile receptor that responds to deep
pressure?
5. Receptors will receive strong and weak stimuli; how do they
respond to the different stimuli?
6. What is referred pain?
7. How do mechanoreceptors operate?
8. Which brain area regulates most homestatic
mechanisms?
9. A receptor field...
1. Provide a general definition for the concept of sensory
adaptation. If you were a marketing manager for an air freshener
company, why should you be concerned about sensory adaptation? At
least two different household products are available in the
marketplace that makes use of the phenomenon of sensory adaptation:
Febreze’s NOTICEables. and Glade’s Lasting Impressions Air
Freshener. Both products are air fresheners that use warmed oil to
scent the air with fragrances. Explain, from a psychological
standpoint, how this...
Put the sensory transduction events in the proper
order
___ Stimulus binds/stimulates sensory receptor
___ Action potentials travel along the sensory neuron towards
the CNS
___ Neurotransmitter binds to a ligand-gated channel in the
sensory nerve
___ Synaptic vesicles within the receptor release a
neurotransmitter
___ A local potential is created in the sensory nerve
___ A receptor potential is created in the sensory receptor
This type sensory receptor monitors
activity of organ systems.
