BIO PSYCH - EXAM 3 EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS | 100% PASS (A+ CERTIFIED)1. Pain: the discomfort associated with (actual or potential) tissue damage 2. Short term pain withdraw from its source, to engage in recuperative actions and to warn others causes us to... 3. Longer lasting sleep, drinking, eating, etc... that promote recuperation pain encourages behaviors such as... 4. Behaviors as- provides warning to kin and elicits caretaking behaviors from them sociated with (ex. grimacing) pain communication... 8. Transient re- detects painful heat ceptor potential vanilloid type 1 also binds capsaicin from chili peppers 5. The McGill pain questionnaire three aspects of pain 1. Sensory-discriminative dimension (throbbing, gnawing, shooting) 2. Motivational-affective (emotional) dimension (tiring, sickening, fearful) 3. Overall cognitive-evaluative dimension (no pain, mild, excruciating) 6. nocicpetors peripheral receptors on free nerve endings that respond to painful stimuli when tissue is injured the cells release chemical signaling molecules to these nociceptors 7. Different free different stimuli nerve endings re- TRPV1 vs TRPM3 spond to 2 / 34 (TRPV1) found on C fibers 9. Transient recep- detects higher temperatures than TRPV1 tor potential type M3 (TRPM3) does not respond to capsaicin found on A delta fibers 10. A delta fibers large myelinated axons that register pain quickly 11. C fibers thin, unmyelinated axons that conduct more slowly, producing lasting pain 12. Congenital in- a genetic condition that prevents the feeling of pain sensitivity to pain (CIP) particular sodium channel blocked - can't detect pain or odor 13. anterolater- transmits the sensations of pain and temperature to the brain al/spinothalamic system nerve fiber axons - dorsal horns of the spinal cord - synapse on spinal neurons - project across midline - ascend to thalamus - glutamate and a peptide, substance P are released in the spinal cord to boost pain signals 14. Steps of the 1. pain info is carried by rapidly conducting myelinated A delta fibers and slowly anterolater- conducting unmyelinated C fibers al/spinothalamic 2. Axons of dorsal horn neurons cross the midline (at base) and ascend the spinal system cord in the anterolateral quadrant 3. Pain info is provided to various brainstem sites, which control pain-related behavior such as vocalization 4. Pain info is distributed to many thalamic and cortical areas 5. Cingulate cortex is especially activated by pain information 3 / 34 15. Substance P peptide released in spinal cord to boost pain signals an remodel neurons mice lacking substance P cannot feel intense pain, but they can feel mild pain 16. gate control theory 17. analgesia spinal "gates"
