Final answer:
Pain can evoke physiological arousal and emotional experience. There are two types of pain: inflammatory and neuropathic. Nociceptors transduce painful stimuli.
Step-by-step explanation:
Pain can evoke two distinct responses: physiological arousal and emotional experience. These responses occur simultaneously, but independently, according to the Cannon-Bard theory of emotion. When feeling pain, our bodies mount a fight or flight response while at the same time we experience emotions like fear or discomfort.
There are two types of pain: inflammatory pain, which signals tissue damage, and neuropathic pain, which occurs due to damage or dysfunction of the nervous system. The most effective treatment for pain depends on various factors like its severity and persistence.
Nociceptors, which are specialized sensory receptors, transduce painful stimuli. Mechanical, chemical, or thermal stimuli beyond a certain threshold activate nociceptors and elicit painful sensations. Stressed or damaged tissues release chemicals that activate these receptors.
