1. What is a protective and complex phenomenon composed of sensory experiences (time,space, intensity), emotion, cognition, and motivation?: Answer: Pain 2. Portion of the nervous system responsib... le for sensation and perception of pain can be divided into 3 areas: Answer: A: Afferent pathways B interpretive centersin the brainstem, midbrain & diencephalon C: descending pathways from the brainto the dorsal horn of spinal cord. 3. Nociceptors are pain receptors that detect a wide range ofstimuli and respond to: Answer: Chemical, mechanical, and thermal stimulation 4. The afferent system is: Answer: Composed of nociceptors the dorsal horn of the spinal column (second-order neurons) and afferent neurons in the A´and C fibers(first-order neurons);spinothalamic tract (third-order neurons). 5. Myelinated A´receptor transmission is: Answer: Fast and conveys mechanical andthermal localized pain. 6. Unmyelinated polymodal C fiber transmission is: Answer: Slower and conveyssharp, diffuse burning and aching sensations 7. These primary-order neurons terminate on second-order neurons.: 8. Three classes of second-order neurons modulate pain transmission: Answer: pro-jection cells, excitatory interneurons and inhibitory interneurons. [Show More]
