Antitussives: Halting the Coughing Reflex (Codeine, Dextromethorphan, Tessalon)
Coughing is a complex process that involves an initial response to an irritant, moves up to the medulla, and triggers the abdomen to constrict. Antitussives are a wide range of drugs that attempt to supress the cough response. How do...

Neural Conduction, Action Potential, and Synaptic Transmission
We have probably heard that neurons are the cells that transmit information around the body. But how does this work? Is it actual electricity? Like from the wall socket? What is a synapse? What happens there, in between one neuron and...
