Ligand-gated ion channels, modulates cell excitability by allowing the flow of calcium and sodium ions into the cell. Located at the CNS in neurons and glia. Excess has resulted in schizophrenia, epilepsy, and mania Ligand-gated ion channels, strengthens synapses and involved in strong memory formation. Excess is associated with memory and learning impairments, psychosis, and excitotoxic brain injury Ligand-gated ion channels Functions as post synaptic inhibition by CI-influx Lack of...

NSC EXAM #1 QUESTIONS & ANSWERS 2024/2025 the big picture of synaptic transmission - ANSWERSthumbtack causes mechanically-gated Na+ channels to open, sending an action potential down the axon using voltage-gated Na+/K+ channels, causing voltage-gated Ca2+ channels to open and activate snare proteins that bind synaptic vesicles to the membrane and causes release of NT importance of synapses - ANSWERSrich diversity allows for complex behavior; place where most psychoactive drugs act; defec...

USABO Open Exam 2024 | 100%Correct Answers Verified Latest 2024 Version. 1. Why is myelin important in the nervous system? A. It allows signals to travel faster along axons because depolarization occurs only at myelinated locations. B. It allows signals to travel faster along axons because depolarization occurs only at nonmyelinated locations. C. It bundles the dendrites of adjacent neurons together. D. It increases capacitance across the cell membrane, which helps electrical signals to le...
