Importance of receptors essay
WitrynaThe purpose of this essay is to explain the mechanisms of neural communication, and the influence that different drugs have on this communication. The nervous system is made up of several cells that are called neurons, which are situated inside the Central Nervous System (Martin, Carlson & Buskit, 2013). WitrynaActivation of postsynaptic receptors leads to the opening or closing of ion channels in the cell membrane. This may be depolarizing —make the inside of the cell more positive—or hyperpolarizing —make the inside of the cell more negative—depending on the ions involved.
