Get up close and personal with your
innards with these 15 amazing 3D-body shots.
下面请亲密接触你内脏这15个令人惊奇的三维人体扫描。

Almost all of the following images were captured using a scanning
electron microscope (SEM), a type of electron microscope that uses
a beam of high-energy electrons to scan surfaces of images.
大部分的图像用扫描电子显微镜(SEM)捕获的，SEM(Scanning Electron
Microscope)是一种使用高能电子束扫描表面图像的电子显微镜。

The electron beam of the SEM interacts
with atoms near or at the surface of the sample to be viewed,
resulting in a very high-resolution, 3D-image.
SEM的电子束与样本表面的原子相互作用使其能够被观察，因此能产生一个非常高清晰度的三维图像。

Magnification levels range from x 25
(about the same as a hand lens) to about x 250,000.
放大率水平从25倍 （约一样手镜头时）到约250000倍。

Incredible details of 1 to 5 nm in size
can be detected.
可以侦测1至5纳米大小的难以置信的细节。

1. Red blood cells 红细胞

They look like little cinnamon candies
here, but they’re actually the most common type of blood cell in
the human body – red blood cells (RBCs).
从这张图片上看血红细胞像小肉桂糖果，但实际它们上是人体内最常见的血细胞-红细胞(RBCs) 。

These biconcave-shaped cells have the tall task of carrying oxygen
to our entire body; in women there are about 4 to 5 million RBCs
per microliter (cubic millimeter) of blood and about 5 to 6 million
in men.
这些两面凹陷状的细胞的主要任务是携带氧气到我们的整个身体;妇女每立方毫米的血液大约有400万至500万个红细胞，男人大约500至600万。

People who live at higher altitudes
have even more RBCs because of the low oxygen levels in their
environment.
居住在高海拔地区的人，因为他们生活在氧气水平更低的环境，体内的红血球数量更多。

2. Split end of human hair 分叉的发梢

Regular trimmings to your hair and good
conditioner should help to prevent this unsightly picture of a
split end of a human hair.
经常修剪和良好的护理，可有助于防止像这张图片上出现发梢分叉的现象。

3. Purkinje neurons 浦肯野神经元

Of the 100 billion neurons in your
brain , Purkinje neurons are some of the largest.
在大脑里的1000亿个神经元中，浦肯野神经元是体积最大的。
Among other things, these cells are the masters of motor
coordination in the cerebellar cortex.
除其他外，这些细胞是小脑皮层里的运动协调大师。
Toxic exposure such as alcohol and lithium, autoimmune diseases,
genetic mutations including autism and neurodegenerative diseases
can negatively affect human Purkinje cells.
接触酒精、锂等有毒物质、患有自身免疫性疾病,包括存在孤独症和神经退行性疾病 等遗传变异，都会对人类的浦肯野神经元造成负面影响。

4. Hair cell in the ear 耳毛细胞

Here’s what it looks like to see a
close-up of human hair cell stereocilia inside the ear.
这张图片看起来就像是在耳朵里面对耳毛细胞进行近距离观察时拍摄的。

These detect mechanical movement in
response to sound vibrations.
耳毛细胞检测响应声音震动的机械动作。

5. Blood vessels emerging from the
optic nerve 从视神经中浮现出的血管

In this image, stained retinal blood
vessels are shown to emerge from the black-coloured optic
disc.
在此图像中，显示染色的视网膜血管从黑色视盘中延伸出来。

The optic disc is a blind spot because
no light receptor cells are present in this area of the retina
where the optic nerve and retinal blood vessels leave the back of
the eye.
因为视网膜的这个区域没有光感细胞，视神经和视网膜血管从眼睛后面的这个部位延伸出去，所以视盘是一个盲点。

6. Tongue with taste bud 舌头上的味蕾

This colour-enhanced image depicts a
taste bud on the tongue.
这张颜色增强图片描绘了舌头的一个味蕾。

The human tongue has about 10,000 taste
buds that are involved with detecting salty, sour, bitter, sweet
and savoury taste perceptions.
人类舌头上大约有10000味蕾，它们能够感受酸、甜、苦、咸等味道。

7. Tooth plaque 齿菌斑

Brush your teeth often because this is
what the surface of a tooth with a form of “corn-on-the-cob” plaque
looks like.
要经常刷牙往往是因为这是牙齿表面的形成一种的类似“玉米棒”状的齿菌斑。

8. Blood clot 血液凝块

Remember that picture of the nice,
uniform shapes of red blood cells you just looked at?
还记得你刚刚看到的第一张漂亮的红血球图片吗？

Well, here’s what it looks like when
those same cells get caught up in the sticky web of a blood
clot.
这张图看起来像是红血球粘在了血液凝块粘性网上。

The cell in the middle is a white blood
cell.
中间的那个细胞是白血球。

9. Alveoli in the lung 肺泡

This is what a colour-enhanced image of
the inner surface of your lung looks like.
这是一张人类肺部内表面的彩色增强图像。

The hollow cavities are alveoli; this
is where gas exchange occurs with the blood.
图中的洞穴是肺泡，这里是血液交换气体的地方。

10. Lung cancer cells 肺癌细胞

This image of warped lung cancer cells
is in stark contrast to the healthy lung in the previous
picture.
这张扭曲的肺癌细胞图与上面的健康肺部图片形成鲜明的对比。

11. Villi of small intestine 小肠绒毛

Villi in the small intestine increase
the surface area of the gut, which helps in the absorption of
food.
小肠绒毛增加了肠道的表面积，这有助于食物的营养吸收。

Look closely and you’ll see some food
stuck in one of the crevices.
仔细看，你会看到一些食物残渣停留在裂缝上。

12. Human egg with coronal cells
带有冠细胞的人类卵子

This image is of a purple,
colour-enhanced human egg sitting on a pin.
这是一张紫色彩色增强图片，人类卵细胞坐落在一个柱状物上。

The egg is coated with the zona
pellicuda, a glycoprotein that protects the egg but also helps to
trap and bind sperm.
这个卵子的透明带状物pellicuda ，一种糖蛋白，它既保护卵子，而且还有助于诱惑和限制精子结合。

Two coronal cells are attached to the zona pellicuda.
两个红色冠细胞附着在透明带状物pellicuda上。

13. Sperm on the surface of a human egg
卵子表面的精子

Here’sa close-up of a number of sperm
trying to fertilise an egg.
这张图片近拍了大量精子尝试给一个卵子受精的场景。

14. Human embryo and sperm 人类胚胎和精子

It looks like the world at war, but
it’s actually five days after the fertilisation of an egg, with
some remaining sperm cells still sticking around.
这看起来来像一个战争的世界，但它实际上受精五天后的卵子，一些剩余的精子细胞仍然坚持粘在卵子表面。

This fluorescent image was captured
using a confocal microscope.
这种荧光图像是利用共聚焦显微镜捕获的。

The embryo and sperm cell nuclei are
stained purple while sperm tails are green.
胚胎和精子细胞核呈紫色，而精子的尾巴是绿色。

The blue areas are gap junctions, which
form connections between the cells.
蓝色区域是缝隙接合区，它们把细胞彼此联系在一起。

15. Coloured image of a 6 day old human
embryo implanting
