NERVE IMPULSES
\n<\/span><\/strong><\/span><\/span><\/p>\n

An impulse begins in the nucleus of the neuron\/cell with the movement of electrically charged inorganic molecules through the cell’s membrane. <\/span><\/span><\/span><\/p>\n

This membrane is semi-permeable. It allows some charged molecules, known as ions, to pass more easily than others. <\/span><\/span><\/p>\n

Potassium<\/span><\/span><\/span> <\/span><\/span>(K+), which is positively charged, is the most prominent ion that passes easily through a neural membrane in its resting state. <\/span><\/span><\/span><\/p>\n

The resting potential in its base state is about a minus 70 mV relative to the outside. An equilibrium will result from the distribution of these ions on either side of the membrane. <\/span><\/span><\/p>\n

The passage of a nerve impulse changes the equilibrium. Sodium<\/span> (Na+), positively charged, and chloride<\/span> (Cl-), negatively charged, have more difficulty passing through.<\/span><\/span><\/p>\n

Large, negatively charged molecules inside the cell cannot get out but do influence the membrane’s electrical potential. <\/span><\/span><\/p>\n

The calcium<\/span> ion (Ca++) plays also an important role in the chemical process of synaptic transmission.
