Curare: Curare is a common name for various plant extract alkaloid arrow poisons originating from Central and South America. These poisons function by competitively and reversibly inhibiting the nicotinic acetylcholine receptor (nAChR), which is a subtype of acetylcholine receptor found at the neuromuscular junction.Toxiferine: Toxiferine (C-toxiferine I) is a curare toxin. It is a bisindole alkaloid derived from Strychnos toxifera and a nicotinic acetylcholine receptor antagonist.End-plate potential: End plate potentials (EPPs) are the depolarizations of skeletal muscle fibers caused by neurotransmitters binding to the postsynaptic membrane in the neuromuscular junction. They are called "end plates" because the postsynaptic terminals of muscle fibers have a large, saucer-like appearance.Beta-Bungarotoxin: β-Bungarotoxin is a form of bungarotoxin that is fairly common in Krait (Bungaros multicinctus) venoms.MyotoniaSuccinylmonocholineNeostigmineHemiphractidae: The Hemiphractidae are a family of frogs from South and Central America. Previously, this group had been classified as a subfamily (Hemiphractinae) under family Hylidae.
