It can affect any bone, and for in about half of affected people, multiple sites are damaged. [5] Avascular necrosis most commonly affects the ends of long bones, such as the femur. Other common sites include the humerus (upper arm), [6] [7] knees, [8] [9] shoulders, [6] [7] ankles and the jaw. [10]
An action potential (also known as a nerve impulse or "spike" when in a neuron) is a series of quick changes in voltage across a cell membrane. An action potential occurs when the membrane potential of a specific cell rapidly rises and falls. [1] This depolarization then causes adjacent locations to similarly depolarize.
The slope of phase 0 on the action potential waveform (see figure 2) represents the maximum rate of voltage change of the cardiac action potential and is known as dV/dt max. In pacemaker cells (e.g. sinoatrial node cells ), however, the increase in membrane voltage is mainly due to activation of L-type calcium channels.

In neuroscience, an excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential. This temporary depolarization of postsynaptic membrane potential , caused by the flow of positively charged ions into the postsynaptic cell, is a result of opening ligand-gated ion ...

The first relies on its mechanism of action, or how the action of the diseases affects normal functioning (whether it is through mutations in genes or more direct pathways such as poisoning). This category divides neuromuscular diseases into three broad categories: immune-mediated disease , toxic/metabolic and congenital syndromes.
