Intercarpal Ligaments


We just learned about the Carpal Ligaments that connect the forearm bones to the carpal wrist bones.

Another group of ligaments are the Intercarpal Ligaments that connect the carpals to each other.

There are eight different carpal bones in the wrist, so these ligaments connect them all together.

Carpal Ligaments


We just learned about the Radioulnar ligaments that connect the forearm bones.

Another set of ligaments is the Carpal Ligaments, that connect the radius and ulna to the carpal bones in the wrist.

There are six different ligaments, all named for where they are and what they connect.
The bones are the radius, ulna and carpals.
The places are "dorsal" back or top of the hand, "palmar" palm side of the hand, and "collateral" sides of the wrist.

Dorsal radiocarpal - Top of the hand, connects radius to carpal
Dorsal ulnocarpal - Top of the hand, connects ulna to carpal

Palmar radiocarpal - Palm side of the hand, connects radius to carpal
Palmar ulnocarpal - Palm side of the hand, connects ulna to carpal

Ulnar collateral - Side of the wrist, connects ulna to carpal
Radial collateral - Side of the wrist, connects radius to carpal

Radioulnar Ligaments


We just learned about the Ulnar Collateral Ligament in the elbow.

The two bones in the forearm are connected together by a few ligaments that hold on to them, like strings strapping the two bones together.

The Proximal Radioulnar Articulation is by the elbow, and the Distal Radioulndar Articulation is by the wrist.

Ulnar Collateral Ligament


We just learned about the Humeroradial Ligaments or RCL that connects the upper arm called the humerus to one of the forearm bones called the radius.

Another bunch of connective tissue connects the humerus to the other forearm bone called the ulna.
This is the Ulnar Collateral Ligament, sometimes just called the UCL.

Just like the RCL, the UCL helps hold the elbow joint together when you move your arm around.

Humeroradial Ligaments


We just learned about the Glenhumoral Ligaments in the shoulder.

Another piece of connective tissue is the Humeroradial Ligaments.

The upper arm bone is the humerus, and one of the bones in the forearm is the radius.
So the humeroradial connects the humerus to the radius.
Sometimes it is just called the RCL for radial collateral ligament.

Glenohumeral Ligaments


We just learned about the Scapula & Clavicle Ligaments.

Another group of ligaments are the Glenohumeral Ligaments that connect the humerus (upper arm bone) to the scapula (shoulder blade or wing bone), and helps hold the shoulder in place.

The scapula has a part sticking out called the coracoid process that helps it get tied to the other bones, and it has a part called the glenoid cavity which is like a rounded holder where the shoulder bone goes to help hold it in place.

The ligaments are:
- Capsule - Goes around the outside of the humerus bone
- Coracohumeral - Connects the coracoid process which is part of the scapula to the humerus bone
- Glenohumeral - Connects the glenoid cavity which is part of the scapula to the humerus bone
- Transverse humeral - Connects two parts of the humerus together
- Glenoid labrum - Helps make the glenoid cavity more stable and bigger

Scapula & Clavicle Ligaments


We just learned about the Sternoclavicular Ligaments that connect your clavicle to your ribs and sternum.

We learned long ago that the clavicle (collarbone) and scapula (shoulder blade or wing bone) work together to hold the ribs and shoulders.

Another group of ligaments are the ones connecting the Scapula & Clavicle.

They are connected with a few different ligaments, at different parts of the bones.

The coracoid process and acromion are two parts of the scapula that stick out and hang on to ligaments that are tied to the clavicle.

The ligaments are:
Acromioclavicular - connects the clavicle to the acromion
Coracoclavicular - connects the clavicle to the coracoid process
Coracoacromial - connects the acromion to the coracoid process
Superior/inferior transverse scapular - covers part of the scapula to help hold nerves and blood vessels

Sternoclavicular Ligaments


We just learned about the Posterior Sacroiliac Ligament that connects your hip to your tailbone.

Another connective tissue way up by the shoulder is the Sternoclavicular Ligaments.

Remember the Sternum is the bone in the middle of your chest, and the Clavicle is the collar bone that connects the sternum to the shoulder.

There are 4 different Sternoclavicular ligaments, that connect to different parts of the body:

Anterior sternoclavicular (connects the clavicle to the front of the sternum)
Posterior sternoclavicular (connects the clavicle to the back of the sternum)
Interclavicular (connects the left and right clavicles)
Costoclavicular (connects the clavicle to the ribs)

Posterior Sacroiliac Ligament


We just learned about the Costoxiphoid Ligaments that connects the ribs to the xiphoid process.

Another piece of connective tissue is the Posterior Sacroiliac Ligament.

This is a large bunch of tissue that connects the sacrum (tailbone) to the ilium (hip bone), on the posterior (back) part of the body.

Costoxiphoid Ligaments


We just learned about the Superior Costotransverse Ligament that connects your spine to your ribs.

Another piece of connective tissue in the body is the Costoxiphoid Ligaments.

These are ligaments that connect the rib, sometimes named the "costo" to the xiphoid process in the middle of the chest.

Superior Costotransverse Ligament


We just learned about the Radiate Ligament of Head of Rib that connects the ribs to the spine.

Another connective tissue in the body is the Superior Costotransverse Ligament.

This is a piece of tissue that connects the rib to the part of a vertebrae called the Transverse Process.
The transverse process sticks out from the back of the vertebrae in your spine, and the rib is tied to it by this ligament.

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.

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.
