Radiate Ligament of Head of Rib


We just learned about the Posterior Longitudinal Ligament that goes down the back of the spine.

Another piece of connective tissue is the Radiate Ligament of Head of Rib.

This ligament connects the rib bone to the vertebrae on your spine.

Posterior Longitudinal Ligament


We just learned about the Invertebral Disc that gives padding on the spine.

Another ligament that helps cushion the spine and hold it in place is the Posterior longitudinal ligament.
This connective tissue goes up and down in the middle of the spine.

Intervertebral Disc


We just learned about the connective tissue the Supraspinous Ligament that goes over the back of your spine.

Another piece of connective tissue is the Intervertebral Disc, or the Intervertebral Fibrocartilage.

This is the piece of cartilage that is in between each of your vertebrae in your spine.

These discs protect each of your vertebrae from bumping against each other, and also helps hold them together.
They also work like shock absorbers so when you are jumping up and down, all the vertebrae in your spine have soft cushions between them.

Supraspinous ligament


We just learned about the Xiphoid Process in the chest.

Another two important pieces of connective tissue are the Supraspinous ligament and Nuchal ligament.

These ligaments are on the outside of the back of your spine, covering the bony part of the back of your spine.
The nuchal ligament goes from your head to the middle of your back, and the supraspinous ligament goes from your back all the way to the bottom of your spine.

Xiphoid Process


We just learned about the Costal Cartilage.

Another piece of connective tissue in the body is the Xiphoid Process.

This is a small piece of cartilage on the bottom of the sternum, in the middle of the chest.

The xiphoid process connects the chest to many other parts of the body, like the muscles used for breathing or moving your stomach area around.

Costal Cartilage


We just learned about the Temporomandibular Ligament.

Another piece of connective tissue is the Costal Cartilage.

This cartilage is in the chest, on the front part of the ribs where the ribs connect together in the middle of the chest.

With this cartilage in the ribs, it lets the rib cage move a little, which allows your chest to get bigger and smaller as you breathe.

Temporomandibular Ligament


We just learned about the Skull Suture Tissue.

Another ligament is the Temporomandibular Ligament.

This is a ligament that connects the your bottom jaw to your head, right up by your ear.

Skull Suture Tissue


We just learned about Cartilage.

There are some types of connective tissue that we can feel, like the cartilage in our ears and noses, or ligaments and tendons in our arms and legs.

But connective tissue is all over the body, even in our skulls!
The bones of the skull are in different pieces, and the pieces are connected with things called sutures.

When a baby is born, the skull pieces are not connected tightly together, there is just connective tissue holding them together.
As the baby gets older, the bones get closer and eventually the sutures get hard and don't move anymore.

All the different parts of the skull that are connected have a little bit of connective tissue in between them to cushion where the bones are connected.

Cartilage


We just learned about the Dense Connective Tissue.

Another type of connective tissue is cartilage.

This is a type of tissue that covers and protects bones.

You can find cartilage in the rib cage, ear, nose, bronchial tubes, vertebral discs, and lots of other places in the body.

It is not as soft as muscle, but not as hard as bone.

Dense Connective Tissue


We just learned about Sharpey's Fibres.

The tendons and ligaments we've learned about are examples of what is called Dense Connective Tissue.

This tissue is usually made up of the collagen we learned about, and dense connective tissue is also found in the dermis part of the skin that we learned about.

Sharpey's Fibres


We just learned about the ligament.

We know that tendons connect muscles to bones.
The part where the tendon is actually connected to the bone is tied to the bones with something called Sharpey's Fibres.

These are made of collagen, and they are tied into the outer parts of the bone so that the muscle stays connected.

Ligament


We just learned about the Collagen.

Another type of connective tissue is the ligament.

We learned before that tendons connect muscle to bone.
Ligaments connect bones to other bones.

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!

Paronychium


We just learned about the Eponychium and Cuticle.

Another part of the nail is the Paronychium.

This is the skin on the left and right sides of the nail.

Eponychium and Cuticle


We just learned about the Lunula.

Another two parts of the nail are the eponychium and cuticle.

The cuticle is the part of the skin right above the beginning of the nail or the lunula.
The skin on the cuticle is dead, and is sometimes removed when someone gets their nails done for a manicure.

The eponychium is the living part of the skin that is right before the cuticle, and it is where the cuticle grows from.

Lunula


We just learned about the Nail Plate.

Another part of the nail is the Lunula which means "little moon".

This is the small white crescent shape at the base of your nail, right where it touches the skin and your nail starts.
The lunula is connected to the matrix and the plate, and is the starting point where your nail grows out from the matrix.

Nail Plate


We just learned about the nail matrix.

Another part of the nail is the nail plate.

This is the big flat part of your nail.
When new cells are being made in the matrix, they are pushed forward to the plate, where they eventually end up at the tip of your fingernail.

Nail - Matrix


Let's learn a little more about nails.

One part of the nail is the matrix.
This is the skin underneath the very bottom part of the nail, below where the nail meets the skin.

The matrix has nerves and blood vessels, and it is the part that makes new cells that turn into the nails.
