Collagen


We just learned about Tendons.

Another part of connective tissue is Collagen.

This is mostly what tendons and other connective tissue are made up, along with skin and many other parts of the body.

Collagen is a protein, that under a microscope looks long and stringy and wraps around other collagen long strings.
These long strings all together work to make a bigger rope.

Tendon


We just learned a little about the Connective Tissue.

One type of connective tissue is a Tendon which connects muscle to bone.

Tendons are like a bunch of long thin ropes all bundled together, wrapped in and around the parts or your muscle, and then tied into your bone.

When your muscles tighten, the tendons stretch out until they are tight, just like a rope gets tighter when you pull on it.
As it gets tight, it pulls on the bone it is attached to, which is what moves your bone around.
So your bicep has tendons connected to your forearm, and when you want to bend your elbow, your biceps pulls on your tendon which pulls on the bone and it bends!

Connective Tissue


We've learned a lot about the Integumentary System, everything from skin to hair to nails!

Another important part of the human body is all of the Connective Tissue that holds things together.
Tendons are connective tissue that connect muscle to bone, and ligaments connect bone to bone.
All of these types of cells are very important or our muscles and bones would not work together.
They are almost like the strings in a puppet, and without them we fall down!
