Transcript of THE SKELETAL SYSTEM :)

The Skeletal System
What is the Skeletal System?
Your Skeletal system is all of the bones in the body and the tissues known as: tendons, ligaments and cartilage.
Do your teeth count as bones?
Your teeth are a part of your skeletal system but they aren't bones. Your teeth are made of enamel and dentin.

The brain, eyes, heart, lungs and spinal cord are protected by your skeleton.Your cranium protects your brain and eyes, the ribs protect your heart and lungs and your vertebrae protects your spinal cord.
Now let's talk about the skeletal system!
The Cranium
Your cranium is also known as your skull. It helps protect the brain. Did you know that the skull has 22 bones in it!
The Mandible
The mandible is the largest and strongest bone in the face! The mandible is the only movable part of the skull.
The clavicle is also known as the collarbone. It connects to the scapula and the sternum. The clavicle is the most common bone that's broken in the body.
The sternum is a flat bone that is in the middle of the rib cage. Bears, birds and other animals have sternums too.
The humerus is also known as your funny bone. The humerus is the largest bone in the arm.
You have twelve pairs of ribs. In the front of your body they attach to your sternum. In the back of your body they connect with the vertebrae.
The ulna is a long thin bone. It is next to the radius in the lower arm.
The sacrum is a large, triangular bone at the base of the spine. It has five vertebraes.
skeletal diseases
Osteoporosis is when you can lose bone tissue. In osteoporosis, the bone loses calcium, gets thinner, and sometimes disappears altogether! Since the bone loses calcium you have to get a lot more of that. Also getting physical activity is great because it builds up your muscles and bones.
1. Osteoporosis
2. Arthritis
3. Bone Cancer
Arthritis affects the skeletal system and the joints. The most common age to get arthritis is fifty-five. Do you want to get rid of arthritis if you have it? Start by being healthier and get rid of any processed foods in your diet. Also it could help if you have multi-vitamins.
Phalanges are also known as your fingers and toes. You have 14 Phalange bones in both your hands and feet, for a total of, 56 phalanges!
Press on the back of your hand and you can feel your metacarpals. Did you know your knuckles are also a part of your metacarpals.
Carpals are bones that make the wrist joint. There are eight carpal bones in your wrists.
The femur is the largest bone in the body. It's also known as your thigh bone. The femur is the longest, strongest, and heaviest bone in the body.
Your tarsals are your anklebones. There are 7 tarsal bones in your foot. Your tarsal bones help you move your foot.
The fibula is on the out side of your tibia. The fibula's main use is to keep the muscle around it together.
The tibia is also called the shinbone. This bone is the second largest bone in the body.
The patella connects with both the femur and tibia. It is known as the knee cap too.
Bone cancer is rare to get. It's when your bones start to weaken. Bone cancer can happen on any bone but mostly on longer bones.
There are five metatarsals. Each metatarsal connects to each toe.
Phalanges are also in your hand. Two other words for Phalanges is toes and fingers
The scapula is also know as your shoulder blade. It connects the humerus to the clavicle.
There are two other names for the vertebrae: Spine and back bone. In fact there are thirty three Vertebraes.
The radius is one, of the two bones in the forearm. It starts at your elbow and goes all the way to your thumb.
The pelvis has four parts. The left and the right hip bone, the coccyx and the sacrum.
How does the system work?
It shapes, supports and protects the organs. The skeletal system helps the body move, produce blood and stores minerals.
