How are potassium ions typically moved out of a neuron when the membrane is at rest? (a)the sodium-potassium pump moves potassium ions out of the cell. (b) Potassium ions are stable and do not move when a membrane is at rest. Chemical gradients move potassium ions out of the cell. (d) Electrical gradients move potassium ions out of the cell. 10. During an AP scoliosis x-ray the patient has re- received a radiation dose of 3 mGy into his breast, gonads, and stomach.

What is the total effective dose? Note that Wt(breast) – 0.05, Wt(gonads) :0.2, Wt(stomach) = 0.12. (a) 0.32 mSv (b) 0.0035 mSv (c) 56mSv (d) 0.96 mSv E
