Document Summary
Learning outcomes: describe neurotransmitter and synaptic physiology, list common neurotransmitters (adrenaline/noradrenaline, acetylcholine, glutamate, Gaba), their receptors and effects: describe the processes involved in the regulated release of neurotransmitters, outline the metabolism (production and destruction) of common neurotransmitters, describe the formation of both ipsps and epsps. + nerves communicate to nerves, muscles and glands. + nerve o nerve communication by neurotransmitters the trigger zone. Trigger zone is where action potential is generated. Cant go back because in refractory period. Axon joins up with dendrites of the next nerve. Neurotransmitters released into synapse to diffuse across and attach to. Involved in production and release of neurotransmitters receptors on next neuron. Psp= electrical change involving ions across a membrane. Makes it more or less likely to produce an action potential. There is a charge gradient and a huge concentration gradient. When you open a potassium channel> opposite occurs> inhibitory> hyperpolarized. Chloride also hyperpolarizes but flows the other way.
