 Jeannot and Sameer: Hi I'm Jeannot and I'm Sameer We will be telling you today about the skeletal system. Jeannot: Did you know that the human body consists of 206 bones! Sameer: The skeleton is a very important part of your body. They allow us movement and our body shape it acts as frame work that supports our body Jeannot: Another function of the skeleton is that it stores important minerals such as calcium Sameer: Also the skeleton protects your inner organs ( such as brian the cranium protects it), makes red boold cells and osteocytes. Jeannot: making red blood cells is very important because the red blood cells carry the oxygen throughout your body. Sameer:Now we are going to name off the main bones of you body Jeannot: First we will start with your cranium this is very important because it protects your brain. Sameer: The maxilla is the upper part of the jaw and it holds the teeth. It helps you chew your food. Jeannot: Now the mandible is the lower part of the jaw. It also holds the teeth together and helps you chew your food too.  Sameer: The spine is made of irregular bones called vertebrae. In between each vertebrae there is cartilage.  Jeannot:The spine is very flexible and allows us to move. We have a curve in our spine so that we can balance our body.  Sameer: Most people have 12 pairs of ribs. The ribs are connected to cartilage and the <span style="color: rgb(0, 0, 0);"> cartilage is attached to the sternum. ( breastbone ). <span style="color: rgb(2, 3, 2);"><span style="color: rgb(0, 0, 0);">Jeannot: The ribcage protects your heart and lungs.

<span style="color: rgb(2, 3, 2);">
<span style="color: rgb(2, 3, 2);">Sameer: It also helps because when you fall on the front, your rib protects it.

Jeannot: Attached to the ribs are the clavicle.

Sameer: The clavicle is your collarbone and helps your shoulders stay in place.

Jeannot: Below the clavicle is the humerus. The humerus shown is attached to the ulna and radius.

Sameer: The ulna, radius, and humerus make up our arm.

Jeannot: This is the hand. It is made of metacarpals, carpals, and phalanges.

Sameer: It has spaces to allow movement so your hand can flex.

Jeannot: Now for the pelvis and femur. The pelvis has a circular socket where the femur goes to. They go in kind of like puzzle pieces. There is cartilage between the pelvis and femur to avoid rubbing.

Sameer: The lower spine is also connected to the pelvis and is known as the coxyx.

Jeannot: The femur connects to the fibula and the tibia. The fibula and tibia are connected to the femur.

Sameer: They also have cartilage to avoid the rubbing.

Jeannot:Finally we have the foot. The foot is made of metatarsals, tarsals, and phalanges.

Sameer: The foot has spaces in between the bone but has growth plates and cartilage to allow movement.

Jeannot and Sameer: Thanks for watching! See you next time!
