It crosses in the medulla, which is at the base of your brainstem.

它穿过，位于脑干底部。

The inner portion is the renal medulla and the outside rim is the renal cortex.

内层为肾，外层为肾皮。

Beneath that is the medulla, a set of cone-shaped masses of tissue that secrete urine into tiny sac-like tubules.

下面是一锥，将尿液分泌到微小囊状小管中。

B-cells differentiate into plasma cells, which are found in the medulla or center of the lymph node.

Children with a tumor in the adrenal medulla can have a large, painful abdominal mass that causes abdominal swelling.

The medulla, for instance, is responsible for heart rate and respiration.

例如，负责心率呼吸。

The inner radially striated layer is the renal medulla.

内放射状横纹层是肾。

The medulla is the inner core.

即其内层。

There are three major regions of the kidney, cortex, medulla and the renal pelvis.

皮、肾盂。外层颗粒状层是肾皮。

The sympathetic neurons releases norepinephrine, also called noradrenaline, and the cells of the adrenal medulla release norepinephrine and epinephrine, also called adrenaline.

交感神经元释放去甲肾上腺素，而肾上腺细胞释放去甲肾上腺素与肾上腺素。

There are also sections of the cortex called renal columns, which extend down into the medulla separating the renal pyramids from one another.

肾柱是肾皮伸入肾，并分隔肾锥体部分。

The ovary itself contains a cortex that houses developing eggs, and a medulla that contains most of the ovary's blood vessels and nerves.

卵巢本身包含一个容纳发育中卵子皮层，以及一个包含卵巢大部分血管神经。

Making the medulla even more salty — and, in turn, more effective at drawing out water from the ascending limb a few steps back.

使更咸——反过来，更有效地从后退几步上肢抽出水分。

So in the final steps, after the filtrate leaves the DCT, it enters the collecting duct, which runs back into the medulla.

所以在最后一步，滤液离开 DCT 后，进入收集管，收集管又回到。

But since it could have been used to store medullary bone, we think that the repetisaurus this osteoderm came from was female.

但由于它可能被用来储存骨，我们认为这种骨皮来自重复龙是雌性。

In the lumbar region, neural crest cells differentiate into the cells of the adrenal medulla, the inner part of the adrenal gland that sits atop the kidneys.

在腰椎节段，神经嵴细胞分化成肾上腺细胞，位于肾脏上方肾上腺内部。

Alright, as a quick recap, neuroblastoma is a condition where neural crest cells of the developing sympathetic nervous system and adrenal medulla do not differentiate normally.

好！简单回顾一下：神经母细胞瘤是由于发育中交感神经链肾上腺神经嵴细胞没有正常分化。

Together, the sympathetic chain and adrenal medulla form the sympathetic nervous system, connecting the brain and central nervous system to various organs including the heart and blood vessels.

交感神经链肾上腺一起成了交感神经系统，将大脑中枢神经系统与各器官连接起来，包括心脏血管。

The remaining filtrate passes from the PCT into the loop of Henle, which starts in the cortex, then dips into the medulla before coming back into the cortex.

剩余滤液从 PCT 进入 亨利氏袢，从皮层开始，然后浸入，然后返回皮层。

They use it to ramp up the concentration gradient earlier in the process, making the medulla even saltier for the filtrate that's back there going through the ascending limb.

在这个过程早期，他们用它来提高浓度梯度，使对穿过上升肢体滤液更咸。
