Introduction:
The sensation is defined as the detection and interpretation of stimuli. Pain is the unpleasant and undesired sensation which may occur due to organ or tissue damage. There are various chemicals which are released by damaged tissue. These chemicals act as stimuli, and the stimuli of pain are dependent on duration, quality, location, and intensity.
Answer to Problem 1SA
Correct answer:
The pain of a stomachache is an example of visceral sensation. Hence, the correct answer is option b.
Explanation of Solution
Reason for correct answer:
Option b. is given as “visceral sensation.”
During stomachache, the sensory receptors present in the wall of the stomach receive the stimulation of pain, so the pain during the stomachache is classified as a visceral sensation
Reason for incorrect answer:
Option a. is given as “somatic sensation.”
During somatic sensation, the receptors present in the skin receive the stimuli, but during the stomachache, the pain is in the internal organ. Hence, option a. is incorrect.
Option c. is given as, “sensory adaptation.”
Sensory adaptation is the phenomena defined as a gradual decrease in the responsiveness of the sensory system as time passes. Hence, option c. is incorrect.
Option d. is given as, “spinal reflex.”
A spinal reflex is a pathway associated with simple behavior of the central nervous system that lies inside the spinal cord. Hence, option d. is incorrect.
Hence, the options a., c., and d. are incorrect.
Stomach ache occurs inside the organ, and the receptors present in the walls of the stomach receive the stimuli, so it is called visceral sensation. Thus, the correct option is b.
