1. EQ: How does the skeletal system Help maintain homeostasis?

2. MAJOR FUNCTION Support Protection Movement Calcium storage
Endocrine regulation
Blood cell production

3. MAJOR parts
Bones
Cartilage
Joints
Ligaments

4. Major Parts
Cranium- the part of the skull that protects the brain. It is the upper part of the skull.
Clavicle- commonly known as the collar bone, the clavicle connect with the scapula and the sternum.
Humerus- commonly known as the funny bone, the humerus is the largest bone in the upper limb.
Scapula- commonly known as the shoulder blade, this is a triangular bone found on the back of the shoulder.
Sternum- commonly known as the breastbone, the sternum is located in the middle of your chest.

5. Major parts (continued)
Rib- in the front of your body, attach to the sternum with flexible cartilage. In the back of your body, the ribs attach to the vertebrae. Your ribs protect your heart and lungs.
Vertebrae- there are 26 vertebrae. They are the bones of the spine. The vertebrae protect the spinal cord.
Ulna- the long thin bone of the forearm.
Radius- one of the two forearm bones.
Carpals- with 8 carpal bones in each wrist, these bones that make up the wrist joint.

6. Major parts (continued)
Metacarpals- the bones of the foot.
Phalanges- commonly known as your fingers and toes, there is a total of 56 phalanges.
Pelvis- your hip bones.
Femur- commonly known as the thigh bone, the femur is the largest bone in the body.
Patella- a round shaped bone known as the kneecap.
Tibia- commonly known as the shinbone, it is the second largest bone in the skeleton.
Fibula- a long bone found on the outside of the tibia. Provides sites for muscles to attach.
Tarsals- the bones in your ankle. There are 7 tarsals.
Metatarsals- the bones of the foot. There are 5 metatarsals.

7. JOINTS The place where two bones meet.
Hinge- a common joint that includes the ankle, elbow, and knee joints
Pivot- a freely moveable joint. Includes neck movement.
Ball-and-socket- these joints have the highest freedom of motion. Includes hip and shoulder.

8. Ligament
Tissue connecting bones to other bones

9. Homeostasis Movement helps us to escape dangerous situations.
Calcium supply

10. WORKING WITH OTHER SYSTEMS
Muscular System- skeletal muscles must be attached to something at either end to give them support while they contract.
Circulatory System- marrow inside of your bones help with producing the cells inside of your blood.
Nervous System- bones give calcium that is important for the proper functioning of the nervous system.

11. 5 Facts
The hands and feet contain more than half of the body’s bones(hands have 27 each & feet have 26 each)
Bones aren’t the hardest thing in your body, but the tooth enamel, another part of this system is.
A babies skeleton has 94 more bones than an adult’s
The phalanges located in your feet are the most fragile bones in your body
Your bones are actually made of living cells, and can contract tumors
