Document Summary
Neurotransmission :- the transmission of information between neurons. It involves a neuron releasing neurotransmitters into a synapse, which allows for these released neurotransmitters to act on sites of another neuron. The study of neurotransmission involves: looking at the events inside the neuron that causes the production and release of neurotransmitters the actions of neurotransmitters on sites situated on other neurons. Electrical transmission :- series of electrical events that begin at an axon hillock and proceed down the length of an axon and they depend on electrical potentials. Electrical potential :- the difference between the electrical charge within a neuron and the electrical charge of the environment immediately outside the neuron. The electrical charge within a neuron is negative compared to the outside environment in normal conditions. This particular characteristic keeps the neuron"s membrane polarized :- keeping one side of the membrane negative, while the other side is positive note: fig 3. 1.
