Physiology of Pain
İletim yolları
Pain receptörleri ortak da olsa central sinir sistmine iletim yönünden ikiye ayrılırlar: Fast and Slow
-
Slow Fibers
mechanical, thermal, chemical(mostly)
use type C fibers at velocities between 0,5 and 2 m/sec
-
-
Analgesia System
-
component
Periaquaductal gray and Periventricular area of mecencephelon and upper pons surround the aquaduct uf Sylvius and portions of third and fourth ventricls
Raphe Magnus Nucleus and thin midline nucleus located in lower pons and upper medulla and nucleus reticularis paragigantocellularis
-
-
Tansmitterleri
enkephalin
periventricular nucleiden periaquaductal graydan başlayan fiberların çoğu ralphe nucleusda salgıayarak sonlanır
-
-
seratonin
ralphe nucleustan başlayan fiberlar ise spinal cordun dorsal hornunda salgılayarak sonlanır. Bu aynı zamanda enkephalin salgılanmasına da neden olur

özellikleri
-
İn fact, under some conditions, excitation of pain fibers becomes progressively greater
-
Tüm doku ve organlarda bulunur, sadece beyin dokusu, KC parankiması ve AC alveollerinde bulunmaz

Chemical
some of chemical that excite the chemical type of pain are Bradikinin, Seratonin, Histamine, Potassium ion, Acids, Acetycholine, Proteolytic enzymes
Prostaglin, substance P enhace sensivity of pain ending but do not directly excite them
important in stimulating the slow, suffering type of pain that occur after tissue injury
