Abstract:
Amyloidosis is an uncommon plasma cell dyscrasia affecting Multisystem, characterized by deposition of amyloid proteins in extracellular spaces and the tissues. Reported incidence of amyloidosis is 8 cases per million per year. Deposition of amyloid fibrils occurs in peripheral nerves in 20% of the cases in Primary Amyloidosis. Though. polyneuropathy is one of the presenting manifestations in cases of Primary Amyloidosis, pure autonomic failure without involving peripheral nerves is not a documented entity. Here, we present a case of Primary Amyloidosis presenting as Pure Autonomic Failure (Dysautonomia).

These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which leads...
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...
