Introduction and Objective The action potential is an impulse of electrical activity. Action potential occurs when a neuron sends messages electrochemically down an axon called a nerve impulse. When a neuron is not stimulated or inactive‚ it is at resting potential. When a neuron is at rest‚ the electrical charge on the inside of the neuron is negative while the electrical charge on the outside of the neuron is positive. The resting membrane potential of a neuron is about -70 mV (mV = millivolts)

2 agar plates divided into 4 equal sections were used for this experiment. Each section was labeled with a number from 1-8. 8 Sterile swabs were used‚ 1 for each surface swab. 8 surfaces in my home were then identified that could serve as a fomite and swabbed with a sterile swab that was dipped in distilled water to moisten it. Surface #1 was the garbage disposal in the kitchen sink. It was swabbed
