Concept explainers
General senses include all of the following except
a. touch.
b. vision.
c. temperature.
d. pain.
Introduction :
General senses are defined as the sensations felt through the receptors distributed all over the body. These are connected with the response that reduces the feeling of such sensations. It is different from specific senses in terms of the presence of a specialized structure for the processing of specific sensations.
Answer to Problem 1PL
Correct answer :
The correct answer is option (b) vision.
Explanation of Solution
Explanation/justification for the correct answer :
Option (b) vision. The perception of vision is a type of specific sense which is defined as the potential to translate the information about the objects present in the surrounding environment using the visible light spectrum. It involves many physiological components, together known as the visual system. So, the correct answer is option (b).
Explanation for incorrect answer :
Option (a) touch. The sense of touch makes use of many receptors present on the skin to detect stimuli like vibrations, contours, weight, temperature, shape, texture, tension, pressure and pain. The brain sends the motor signal to move away from the site when it perceives something dangerous. So, this is an incorrect option.
Option (c) temperature. The sense of temperature makes use of many receptors present on the skin to detect cold and hot surfaces. It is observed with reference to body temperature. The brain sends the motor signal to move away from the site when it perceives something dangerous. So, this is an incorrect answer.
Option (d) pain. The sense of pain makes use of many receptors present on the skin to detect stimuli of distress on encountering an object. It is coupled with potential or actual tissue damage. The brain sends the motor signal to move away from the site when it perceives something dangerous. So, this is an incorrect answer.

Sometimes the cause is a problem with the auditory nerve, but in Jills case it has to do with a problem in the inner ear itself.
