WebFeb 28, 2024 · Myelin promotes fast transmission of electrical signals mainly by affecting two factors: 1) increasing electrical resistance, or reducing leakage of the electrical signal … WebOne method of terminating or stopping a specific signal is to degrade or remove the ligand so that it can no longer access its receptor. One reason that hydrophobic hormones like estrogen and testosterone trigger long-lasting events is because they bind carrier proteins.

WebThe steps of transmission across a synapse are the following: Action potential arrives at the axon terminal. Ca^2+ diffuses into the presynaptic cell. Ca^2+ causes exocytosis of synaptic vesicles. Neurotransmitters are released into the synaptic cleft. Neurotransmitters bind to postsynaptic receptors. Either positive ions or negative ions flow ...
