SPOOKY SCARY SKELETONS

Major functions of skeletons includeSupportMovementProtectionRed blood cell productionCalcium storageAnd endocrine regulation

Boring diagram stuff I put very little effort into finding

Ligaments connect one bone toanother creating a joint

Tendons connect muscle to bone

Bones help protect internal organs, Store calcium, and other important stuff

JointsHinge joints are found in places like the ankle, elbow, and knee. They can only move along the axis to flex or extend meaning they can only move one wayPivot joints are freely movable joints that allow rotary movement around a single axis. You will find one of these between the first and second clavicle vertebrae directly under the skull allowing the head to move from side to sideThe only ball and socket joints are the hip and shoulder and ball and socket joints allow for the greatest range of motion of all joints

How the skeletal system works with other systemsSkeletal system cant supply itself with calcium to strengthen itself. It relies on the digestive systemYour brain sends signals to your muscles to contract and when theMuscle moves the bone follows

5 calcium rich facts about spooky scary skeletons

The smallest bones in the body are found in the ear.The longest bone in the body is the femur.The bones are filled with a fatty substance called bone marrow. In this marrow, red and white blood cells are manufactured and then released into the bloodstream.Over half the body's bones are in the hands and feet.The only jointless bone in your body is the hyoid bone in your throat.As your bones grow, you get taller (of course). Your growth in height is likely to stop by the time you are 16 if you're a girl and 18 if you're a boy.

Skeletal system diseases Scoliosis is the curvature of the spine resulting from things like someone's leg being longerthan the other or muscle spasms, Some say that the curves in the spine gives the spine an s like shape (as shown in the image behind)

Osteoporosis is a disease where the bones become fragile and prone to fracture
