3.The reduced potential causes hundreds of a)________________________ channels to open on that part of the cell membrane. The de
wlad13 [49]

The reduced potential causes hundreds of <u>voltage-gated sodium</u> channels  to open on that part of the cell membrane. The depolarization of the cell causes more of <u>voltage-gated sodium </u>channels to open in adjacent parts of the cell membrane. This begins the wave of of <u>depolarization</u>  moving down the axon. Depolarization begins at the <u>axon hillock.</u>

Explanation:

When there is no neuron signaling it becomes polarized, termed as resting membrane potential (RMP) at a threshold voltage (around -55 mV), due to the action of the sodium-potassium pump and the potassium leak channels.  

When a change in the RMP occurs, depolarization takes place which causes the voltage-gated sodium channels to open and sodium ions rush into the nerve cell which in turn will increase the voltage threshold to nearly around +40 mV and also charges the neuron positive. This depolarization moves down the axon. This increase in threshold stops the sodium influx and opens the potassium channels to rush the potassium out of the cell.

All these actions decrease the membrane potential leading to a wave of depolarization and going back to resting state. Depolarization begins depending upon the potential gradient at the axon hillock.

frez [133]
The nurse should position the client at a prone position every 3 to 4 hours for 20 to 30 minutes periods. This should be done periodically. Arterial insufficiency is any condition that slows or stops the flow of blood through your arteries. Arteries are blood vessels that circulate blood from the heart to other parts of the body.

Answer:

23a: The priest and the levite

23b: (from wikipedia) "<em>In Jewish culture, </em><em>contact with a dead body </em><em>was understood to be </em><em>defiling.</em><em> Priests were particularly enjoined to </em><em>avoid uncleanness.</em><em> The priest and Levite may therefore have </em><em>assumed</em><em> that the fallen </em><em>traveler was dead </em><em>and avoided him to </em><em>keep themselves ritually clean."</em>

23c: He took care of himand helped the wounded traveler to recover.
