Physiology 206 Lecture 9 Outline of Last Lecture I. Sensory receptorsII. PainIII. Sympathetic and Parasympathetic NSIV. Ganglions, ganglionic cells Outline of Current Lecture I. Cholinergic neuronsII. Somatic branch of nervous systemIII. Neurotoxins Current Lecture2/3/14- Cholinergic Neuronso Acetylcholine –Achase--> Acetate + Cholineo Neurons that release acetylcholine or receive them- Norepinephrineo Previously called noradrenalineo Neurons that release/receive the are adrenergic or cholinergic- Somatic brancho Motor neurons that innervate muscles (stimulatory) o Use Acho Final common pathway Motor neurons because they are the last to transmit all information to destination- Neurotoxinso Work at the place where motor neurons are stimulatedo Black widow spiders Cause massive release of Ach in every motor neuron Every muscle simultaneously contractsThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute. Can’t breathe = respiratory arresto Botulinum toxin Product of bacteria Most toxic compound Blocks release of Ach Muscles can’t contract Can’t breathe = respiratory
