Lambert-Eaton-Syndrome (1239 words) |
 | The primary physiological disorder in the Lambert-Eaton myasthenic syndrome (LEMS) is a reduced release of the neurotransmitter acetylcholine from the nerve terminals into the synaptic gap. |
 | This presynaptic disorder is caused by autoantibodies against a membrane protein of the nerve cell, the voltage-gated calcium channel (VGCC). |
 | A transient depolarization of the presynaptic membrane causes the opening of the voltage-gated calcium channels, which allows the local influx of calcium ions into the nerve terminal. |
