But with nightfall comes the release of sleepy melatonin hormones from the pineal gland.

但是在晚上，就会从松果体分泌褪激素。

A rare supratentorial pediatric tumor is a pinealoma, which forms in the region of the pineal gland.

还有一种罕童脑幕上肿瘤：松果体瘤，在松果体中形成。

Histologically, prominent features include large, round tumor cells resembling germline tumors; or small cells forming Homer-Wright rosettes.

松果体瘤主要组织学特征包括类似生殖细胞肿瘤中巨大圆形肿瘤细胞，或是形成Homer-Wright菊形团小细胞。

Pinealomas primarily emerge from the endocrine cells of the pineal gland, and they can be grade I through IV.

松果体瘤初发于松果体内分泌细胞，可分I到IV级。

As the sun rises, your pineal gland stops releasing melatonin.

随着太阳升起，你松果体停止分泌褪激素。

Melatonin is a hormone secreted by the pineal gland in your brain.

褪素是由你大脑松果体分泌一种激素。

When the sun goes down, it is released by the pineal gland in the brain.

当太阳下山时，大脑中松果体就会释放这种物质。

So the pineal is not the gland or the organ of sunlight.

所以松果体不是阳光腺体或器官。

Darkness allows the pineal to release melatonin.

许松果体释放褪素。

It's different from the melatonin that we make from our pineal gland.

这与我们从松果体产生褪素不同。

Melatonin is this hormone that's released from the pineal gland.

褪激素是松果体释放一种激素。

Maybe it was 85% subcellular, 5 in the guts, and then 10 from the pineal gland.

也许是85%亚细胞层面，5%在肠道，然后10%来自松果体。

Again, not ideal, but the pineal gland and the part of the hypothalamus is regulated by light.

再次强调，这并不理想，但松果体和下丘脑一部分受光线调节。

All they way up here at the top of our head, like with the pineal gland, the pituitary gland.

一直往上到我们头顶部，比如松果体和垂体。

Now the pineal gland's the most mysterious, misunderstood, smallest organ in the body, yet the most sophisticated.

现在松果体是体内最神秘、最被误解、最小器官，然而也是最复杂。

Remember I said the pineal gland is how we perceive the spiritual energy of God and encountering a pervasive love.

记得我说过松果体是我们感知上帝精神能量和普遍之爱方式。

So, for example, a pinealoma may lead to increased secretion of the hormone beta human chorionic gonadotropin that can cause an early onset of puberty.

比如，松果体瘤可能导致β人绒毛膜促性腺激素分泌增加，可引起青春期发育提前。

Melatonin is naturally produced by your brain, and it's released by a very small gland deep within your brain called the pineal gland.

褪激素由大脑自然产生，由大脑深处一个非常小腺体释放， 称松果体。

As the world goes dark, this master switch tells our pineal gland to increase levels of the hormone melatonin in the bloodstream, sort of like a chemical lullaby.

天下来时，这个主开关告诉我们松果体增加血液中褪激素水平，有点像化学摇篮曲。

Hormones are made by specialised cells mostly found in the endocrine glands, the hypothalamus, testes and ovaries, and the thyroid, parathyroid, pituitary, adrenal and pineal glands.

激素由特化细胞产生，这些细胞主要存在于内分泌腺、下丘脑、睾丸和卵巢，以及甲状腺、副甲状腺、垂体、肾上腺和松果体中。
