Homunculus - Guides d'étude, Notes de cours & Résumés

Pharmacology- Pain and opioids Pain transduction - correct answer 1. painful stimulus arrives at the sensory receptor(nociceptor) 2. ion channels open, inward cation current--> depolarization 3. if exceeds threshold action potential will be fired by the first order sensory neuron located in teh ganglia on the dorsal root of the spinal nerves l is transduced to the second order neuron located in the spinal cord or brain 5. signal then transferred to the contralateral side through one of t...

What is the interpretation of external stimuli by the brain? Sensation Sensation travels through (efferent/afferent) pathways afferent The representation of the sensory system via the somatosensory map is called? sensory homunculus Sensation: precentral gyrus or postcentral gyrus? postcentra

Dermatomes ~~>area of the skin that is mainly supplied by branches of a single spinal sensory nerve root. These spinal sensory nerves enter the nerve root at the spinal cord, and their branches reach to the periphery of the body.

MSK 4 Midterm Exam with Questions and Answers _% of all MSK patients become chronic pain patients ANSWER 25% when does pain occur ANSWER when the brain perceives damage or the threat of damage (not related to the extent of damage) what is the only thing that changes pain perception ANSWER patient education explain the alarm story ANSWER pain threshold is lowered with chronic pain (less stimulus needed) PT should raise the threshold through education of a normal response to the st...

MSK exam questions & answers 2023/2024 What percent of MSK patients become chronic pain pts? - ANSWER-25% Is pain related to the extent of damage? - ANSWER-No it is what the brain precieves it to be. What do we treat? - ANSWER-the dysfunction/impairments identified (includes cognitive aspects too) Alarm story - ANSWER-you have chronic pain it lowers your pain threshold, so it'll take less stimulus for you to reach the pain threshold and experience pain Factors that affect respo...
