#6.2.1.1
The structure of a myelinated motor neurone.
#6.2.1.2
The establishment of a resting potential in terms of differential membrane permeability, electrochemical gradients and the movement of sodium ions and potassium ions.
#6.2.1.3
Changes in membrane permeability lead to depolarisation and the generation of an action potential. The all-or-nothing principle.
#6.2.1.4
The passage of an action potential along non-myelinated and myelinated axons, resulting in nerve impulses.
#6.2.1.5
The nature and importance of the refractory period in producing discrete impulses and in limiting the frequency of impulse transmission.
#6.2.1.6
Factors affecting the speed of conductance: myelination and saltatory conduction; axon diameter; temperature.
