Local anesthesia-Order of nerve blockage

General classification of Nerve fibers as sensory & motor
Classification of Nerve fibers by Erlanger & Gasser A,B& C fibers
-Diameter
-Speed
Proprioception -what it is
A fibers-
Subdivision -
Alpha ,Beta, Gamma & Delta
-Fast 1st pain carried by Delta fibers
C fibers & slow 2nd pain
-Diameter & myelination affecting conduction speed
-conduction velocity & time taken by local anesthetic to block conduction.
-what type of nerves are blocked first & the reason why.
-Advantage of myelination & saltatory conduction
Order of nerve blockage after local anesthesia-
Autonomic first why
-Sensory
Motor last why
SENSORY
-Pain 1st
-Temperature
-Touch
-Pressure last
TASTE BLOCKAGE
-Bitter
-Sweet
-Sour
-Salty
