Document Summary

Resting membrane potential: neurons communicate electrochemically, what is the basis of this electrochemical communication, another word for sodium is natrium. The neuron"s resting membrane potential: inside of the neuron is negative with respect to the outside, difference = approx. Ionic basis of the resting potential neuron: ions, charged particles, are unevenly distributed, they are separated neural tissues that are either positively or negatively charged. 4 ions contributing: sodium (na+)*, chloride (cl-) (forced out by - internal potential, potassium (k+)** (move out of neuron, negatively charged proteins. Synthesized and stay within the neuron: ** at rest sodium high outside , potassium inside but. The neuron at rest differential permeability of the. Membrane: semipermeable phospholipid bilayer (don"t need to know this, only places ions can get through the cell are the ion channels. Negatively charged protein ions do not pass through. Moves 3na+ out for every 2k+ in (uneven)
