Hypokalemia
Definition
Low K+ in ECF, K diffused out of cell, hyperpolarized, morer neg.,
cause: diuretics, anorexia, hyperaldosteronism, excessive diarrhea, vomiting
Term
Hyperkalemia
Definition
more K + ECf increased diffusion of K into cell
caused by kidney failure, hypoaldosteronism
stimulation of nervous system . . .
Term
synaptic transmission at neuromuscular junction
Definition
AP down somatic motor neuron to synaptic knob
voltage gated CA+2 channels open due to reversal of polarity
CA2 enters into synaptic knob causes secretion of Acetylcholine
Ach diffuses across syntic cleft binds to aCh receptor site proteins on the skeletal muscle cell membrane
causes ligand gated Na+ channels to open , Na flows in depolArizes cells causing AP , muscle contraction
ach at receptor site is split into acetate and choline by acetylcholinestrase
ligand gated Na channels close allowing muscle cell to relax
acetyl and choline active reuptake
Term
Acetyl Choline
Definition
binds to nicotinic ACH receptor site proteins
causing ligand gated Na + channels to open
Term
Neuromuscular blocking agent
Definition
curare block Ach receptor sites on skeletal muscles keeping them from contracting
causing flaccid paralysis
- also caused by poliomyelitis , botulism and myasthenia
Term
Acetyl cholinesterase Inhibitors
Definition
prevent acetylcholinesterase from breaking down acetylcholine, it remains attached to ach receptor site Na+ continues to flow onto muscles and they remain contracted.
causing spastic paralysiss, organophosphate insecticides parathion, malathion, sevin & nerve gas tabun, sarin soman
