The adrenal cortex is the outer part of the adrenal gland and is subdivided into three layers- the zona glomerulosa, the zona fasciculata, and the zona reticularis.

肾腺皮质是肾腺外层部，皮质又为三层：球状带、束状带和网状带。

Zona fasciculata is the middle zone and also the widest zone and it takes up the majority of the volume of the whole adrenal gland.

束状带是中间那层，也是最层，占了整个肾腺大部体。

Over time, this lack of stimulation can cause zona fasciculata to physically shrink or become atrophic.

时间长，过少刺激会导致束状带缩小或萎缩。

This causes a decrease in CRH and ACTH, which in turn, shuts down cortisol production from the zona fasciculata.

这会降低CRH和ACTH，反过来阻止束状带制造皮质醇。

With less ACTH floating around, the zona fasciculata gets less stimulation to make cortisol, and eventually, cortisol levels go back down to the normal range again.

随着ACTH减少，束状带受刺激产生皮质醇减少，最后，皮质醇水平降低到正常范围。

The excess ACTH overstimulates zona fasciculata of both adrenal glands, which grow larger and secrete excess cortisol.

过多ACTH会过度刺激两个肾腺束状带，使其增大并泌过多皮质醇。

The first way to make the " r" sound or the " er" sound is we call " the bunched 'r'" .

发出“r” 音或“er” 音第种方法是我们称之为“束状‘r’” 。

Einstein argued that light energy traveled in packets we now call photons, which would essentially make light behave like a particle.

爱因斯坦认为，光能以我们称之为光子束状运动，使光表现得像粒子。
