We use 2 mg of tubocurarine in a demonstration experiment to review its properties as a neuromuscular blocking drug

To emphasize its action mechanism is useful to compare it with 2 mg of Succinylcholine in a chicken model

Pain Poster

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
