Question

Describe nerve impulse transmitted through synapse

Answer 1

Cell membranes surround neurons just as any other cell in the body has a membrane. When a neuron is not stimulated — it’s just sitting with no impulse to carry or transmit — its membrane is polarized. Not paralyzed. Polarized. Being polarized means that the electrical charge on the outside of the membrane is positive while the electrical charge on the inside of the membrane is negative. The outside of the cell contains excess sodium ions (Na+); the inside of the cell contains excess potassium ions (K+). (Ions are atoms of an element with a positive or negative charge.)
