Substance P ________ .
- a. increases pain-related signals
- b. is a natural painki1ler
- c. is the active ingredient in aspirin
Introduction: Pain is a sensation that arises due to some injury or inflammation. The neurotransmitter that acts as substance P enhances pain perception in the body by stimulating pain receptors.
Reason for the correct statement:
Substance P is a neuromodulator that stimulates pain-related signals. They cause spinal interneurons to send more pain-related signals to the sensory cortex. If the level of substance P is elevated in an individual, his perception of pain will be increased.
Hence, option a. is correct.
Reasons for the incorrect statement:
Option b...
