Document Summary
It is critical the message is received and then erased so another can be sent and received. One method of this is by binding to an enzyme that breaks it down. He"s wanting us to consider a variety of changes and how they affect. Manipulation of these things is the basis of pharmaceuticals. Upregulation and downregulation: assumption: with a chemical messenger we are going to see acute or short term changes in neurotransmitter concentration. That way we can change what we are doing. A chronic message would leave your arm contracted. When you do drugs you lose receptors the overwhelming message causes for downregulation. Drugs, toxins, venoms can all work on neuromuscular junctions. Sensory physiology: a signal transduction yields an action potential which then goes to the conscious or subconscious cns, sensation v. perception. Sensation: what happens in your brain when the receptor was stimulated. Occurs in the conscious portion of the brain.
