Snake - Skeleton

We just learned about the Snake - Molting.

Another part of snake biology is the skeleton.

Snakes only have a skull, backbone and ribs, and a few small bones left over from when snakes used to be lizards and had legs.
They can have 200 to 400 vertebrae in their backbone, depending on the type of snake.

Sympathetic Nervous System

We just learned about the Autonomic Nervous System, which is part of the Peripheral Nervous System.

One part of the Autonomic Nervous System is the Sympathetic Nervous System.

This part of our nervous system gives us what we call the fight-or-flight feelings.
That means when something happens that scares you or hurts you, this helps make your decision for whether you run away or whether you fight back.

Insular Mountains

We just learned about the Coast Mountains in the Pacific Coast Belt, in the North American Cordillera.

Another mountain range in that belt is the Insular Mountains in British Columbia, Canada.

These mountains were made from lava, and created the Vancouver Islands and the Haida Gwaii Islands.
The bottom of these mountains goes below the sea level, which is called not fully exposed.

There are still many earthquakes in this area.

Rachel

We just learned about the person from the Bible named Jacob.

Another person from the Bible is Rachel.

Rachel was one of the wives of Jacob.

While Jacob was running away from his brother Esau because he had stolen Esau's birthright and blessing, he was working for a man named Laban.
He saw Laban's daughter Rachel and thought she was very beautiful, so he asked Laban if he could marry her.
Laban said he had to work for him for 7 years before he could marry her, and he agreed.
After 7 years he had the wedding, but Laban tricked him and made Jacob marry Rachel's older sister Leah first.
He agreed to work for Laban for another 7 years and then married Rachel also, so he had two wives.

Rachel was very upset for a long time because she could not have babies, but then after a long time she was able to have two children, Joseph and Benjamin.

Stavelot Triptych

We just learned about the Shrine of the Three Kings.

Another ancient roman sculpture is the Stavelot Triptych.

We learned before that a triptych is like a sculpted book that opens and closes.
This triptych opens up, and has two smaller triptychs in the middle.

The smaller triptychs are much older, and are said to have held small pieces of the cross that Christ died on, as well as some dirt from Christ's tomb, and a piece of his mother Mary's robe.

The triptychs are made of gold, jewels and glass, and have pictures showing saints, mother Mary, and the story of the Christian Emperor Constantine's mother when she traveled to find the cross that Christ died on.

Pig Iron

We've now learned about Sponge Iron and Wrought Iron.

Another type of iron made in a forge is Pig Iron.

This is iron after it has gone through a blast furnace, it is stirred and stirred while heated.
There are a lot of things called impurities in the metals, that make the iron harder to work with or not look as nice.
After heating and stirring, the metal can be cooled and turned into little metal bricks nicknamed "pigs".

They got this nickname because the way the iron was made in molds, it looked like a bunch of little piglets with a larger mother pig.

When they broke off the small pieces from the mother sow, they called them pigs.
