Chapter 16 Review Terms and Questions For all terms provide both a definition and an example Sensory, Motor, and integrative Systems Sensation Perception Identify the following as primarily a sensation or a perception: Sound: Music: Green: Grass: Pressure: Pushing: Why is high blood pressure sometimes referred to as a "silent killer" (people are unaware that they have it)? Explain this in terms of sensation vs. perception. Can a sensory neuron that transmits impulses for the sensory modality of pain also transmit impulses for the sensory modality of vibration? (Explain your answer!) gered? How is an action potential (nerve impulse) in a sensory neuron produced or trig Exteroceptors Interoceptors Proprioceptors In your own words, describe sensory receptor adaptation. Distinguish between rapid and slow adaptation.

Explanation / Answer

1. Sensation is a body's or its organ's detection of external stimulation. It is processing of senses by sense organs.

2. Perception is identification & interpretation of sensory information in order to understand presented information

sensation is a physical stimulus but perception is understanding of that stimulus.

3. Sound is a sensation

Music is a perception

Green is a perception

Grass is a perception

Pressure is a sensation

Pushing is a perception.

4. Untreated high blood pressure increases the risk of stroke and other cardiovascular diseases. It can damage kidneys and may cause Glaucoma& blindness also. So it is referred to as a "silent killer."

All the people are not aware & this awareness is a perception.

5. No. A sensory neuron that transmits impulses of pain cannot transmit impulses of vibration. we have different neurons to sense different types of senses like pain, temperature, touch, vibration and different receptors are there to receive senses. Vibration is found by mechanical pain receptors.

6. Action potentials are generated by special types of voltage-gated ion channels embedded in the plasma membrane. mainly by the opening of sodium channels.

7. Exteroceptors are located at the external surface of the body; They are sensitive to stimuli originating outside the body and transmit information about the external environment. All the sensations of smell, taste, hearing, vision, touch, pressure, pain and temperature etc., are conveyed.

8. Interoceptors are also called as visceroceptors. They are located in blood vessels, visceral organs, muscles, and the nervous system. They monitor conditions in the internal environment of our body. The nerve impulses produced by them usually are not consciously perceived.

9. Proprioceptors are located in Joints, muscles, tendons and the inner ear. They provide information about the position of the body, length of the muscle and its tension, and the position and movement of your joints.

10. Sensory receptor adaptation diminished electric responses of a receptor neuron over time in spite of the continued presence of an appropriated stimulus of strength. Due to the continued same strength of the stimulus, there will be a decrease in sensitivity to that stimulus.

Rapid adaptation - frequency of nerve impulses decreases rapidly.

Slow adaptation - They do not adapt. And how long the stimulus lasts, they will continue to trigger nerve impulses.
