Synaptic vesicle - Study guides, Revision notes & Summaries

Chapter 3 delves into the intricate mechanisms of chemical signalling by neurotransmitters and hormones within the nervous system. It begins with the basic concepts of synaptic transmission, highlighting the directionality from presynaptic to postsynaptic cells and the structural components of synapses, such as axodendritic and axosomatic synapses. The chapter further explores neurotransmitters' synthesis, release, and inactivation, noting the diverse chemical classes, including amino acids, mon...

NTT Exam Questions & Answers 2024/2025 Synapses - ANSWERSFundamental aspect of all brain functionbecause they transmit information between neurons (and to muscle)• act as information filters based on theirindividual properties• one of these properties is the release probability, Pr - average number of vesicles released per spike• can change their properties: both in the short-term and long-term dysfunction and a target for many drugs - short-term changes (depression,facilitati...

NSC Chapter 5 Test with Complete Solutions transporters - Answer-special proteins embedded in the vesicle membrane that concentrate neurotransmitters inside the vesicle once the amino acid and amine neurotransmitters are synthesized in the cytosol and then taken up by the synaptic vesicles. voltage-gated calcium channels - Answer-following the depolarization of the terminal membrane, these channel proteins open and let in Ca++ ions; resulting elevation in the ions is the signal that causes n...

psych 115 midterm 1 UCLA Exam Questions and Answers 100% Pass What is the role of Dorsal root ganglion cells? • DRG = unipolar neurons in peripheral nervous system • Job is to relay somatosensory info from skin to spinal cord Describe a touch stimulus. • Touch to skin generates a receptor potential by opening mechanoreceptor Na channels • Receptor potential passively propagates (flows) to the integration zone • Receptor potential is attenuated (becomes smaller) as it propaga...

Step 1: The Chemical Synapse An action potential arrives at the end bulb. Step 2: The Chemical Synapse Ca++ enters the presynaptic terminal. Step 3: The Chemical Synapse Ca++ interacts with the synaptic vesicle and fuses with the presynaptic membrane. Step 4: The Chemical Synapse Neurotransmitter is released and binds to the postsynaptic transmitter receptor. Step 5: The Chemical Synapse Receptor protein undergoes a change in shape that allows ions to flow. Step 6: The Chemical Synapse...
