Abstract:
Neuromyotonia, or Isaac's syndrome, is a rare neuromuscular disorder of peripheral nerve hyperexcitability characterized by muscle stiffness, muscle hypertrophy, pseudomyotonia, myokymia and electromyographic evidence of myokymic or neuromyotonic discharges. A young boy with neuromyotonia is presented who was diagnosed with tetanus for severe muscle spasms, trismus and ophisthotonos. We discuss differentiation of neuromyotonia from tetanus and other disorders with similar features on clinical and electrophysiological examination.

Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
