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

它穿过髓质，髓质位于脑干的底部。

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

B细胞化为浆细胞；浆细胞存在于淋巴结的髓质（淋巴结的中）。

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

肿瘤长在髓质的患儿会出现巨大且疼痛的腹部包块，造成腹部肿胀。

And in the center of that you have what's called the adrenal medulla.

在中部位，有一个被称为髓质的结构。

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

卵本身包含一个容纳发育中的卵子的皮层，以及一个包含卵大部血管和神经的髓质。

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的交感神经链和髓质的神经嵴细胞没有正常化。

Second, if the baroreceptors are detecting that blood pressure is too high, the cardio regulatory center of the medulla will also decrease sympathetic input to the blood vessels.

其次，如果压力感受器检测到血压过高，则髓质的脏调节中也会减少对血管的交感神经输入。

And from a very tiny, underused part of my brain — probably located at the base of my medulla oblongata where my subconscious dwells — comes the thought: he's here to see you.

在我大脑一个非常小的，不怎么利用的部——也许位于我髓质延髓的根部，我的潜意识存在于此——冒出一个想法：他是来看你的。

Therefore, this response that acts primarily on the cardiovascular system is mediated directly via impulses transmitted through the sympathetic nervous system and indirectly via catecholamines secreted from the adrenal medulla.

因此这种反应主要作用于血管系统，通过交感神经系统直接介导，或通过髓质泌的儿茶酚胺间接介导。

The way dinosaurs manage to get around this problem, essentially keeping its own bone strong or producing strong eggshells, is through the development of a unique type of bone called Medullary Bone.

恐龙设法解决这个问题的方法是通过开发一种称为髓质骨的独特骨骼来保持自己的骨骼强壮或产生坚固的蛋壳。

For the next few hours, as my stomach grows distended from the food, it activates stretch receptors that again stimulate my medulla and get my vagus nerves to tell my stomach to turn up the juice.

在接下来的几个小时里，当我的胃因食物而膨胀时，它激活了伸展感受器，再次刺激我的髓质，让我的迷走神经告诉我的胃把胃酸调高。
