生理学考题回顾

一、英译中：

1. 【10 级临五】Depolarization stage. At this time, the membrane

suddenly becomes permeable to sodium ions, allowing tremendous

numbers of positively charged sodium ions to ow to the interior of

the axon. The normal ploarized state of -90 mv is lost, with the

potential rising rapidly in the positive direction. This is called

depolarization. In large nerve $bers, the membrane potential

overshoots beyond the zero level and becomes somewhat positive,

but in some smaller $bers as well as many central nervous system

neurons, the potential merely approaches the zero level and does not

overshoot to the positive state.

2. 【11 级临五】Within 'a few 10,000ths of a second after the membrane

becomes highly permeable to sodium ions, the sodium channels

begin to close and the pltassium channels open more than they

normally do. Then, rapid di(usion of potassium ions to the exterior re-

establishes the normal negative resting membrane potential. This is

called repolarization of the membrane.
