The Cranium or Skull

The Cranium is your skull and protects your brain.

The Clavicle

The Clavicle or your collarbone is located between the ribcage (sternum) and the shoulder blade.

The Ribs

The ribcage is an arrangement of bones in the thorax of all the vertibres except the lamprey.

The Humerus

The Humerus is a long bone in the arm or in the forelimb that runs from the shoulder to the elbow.

The Vertebrae

The Vertebrae also known as the spine is a bony skeletal structure found in the vertebrates.

The Ulna

The Ulna or elbow bone is 1 of the long bones that run in your forearm.

The Radius

The radius one of the biggest bones in your forearm extends from the lateral side of the elbow to the thumb side

The Pelvis

The pelvis is the lower part of the trunk, between the abdomen and the thigh.

The Femur

The Femur or thigh bone, is the longest, heaviest, and strongest b one in the human body.

The Patella

The Patella also known as the knee cap covers and protects the interior articular of the knee joint.

The Fibula

The Fibula forms the lateral part of the ankle joint. it protects below the Tibia

The Tibia

The Tibia also known as the shin, is the lager and stronger bone in the leg. It is In vertebrates and it connects the knee with the ankle.

Skeletal System Facts

 The skeletal system is the organ system that supports and protects the body and allows it to move. Its other jobs include storing minerals and producing red blood cells. A humans skeleton is inside the body, so it is called endoskeleton.


  Bones are alive! Bones are hard organs made of minerals and connective tissue. They have blood vessels which supply nutrients and nerves which signal pain. The body of a new born baby has about 300 bones, but the average adult has only 206 bones. As a child grows, some bones fuse together. Bones provide support for your body and make it possible for you to sit or stand up upright.


  The tough, flexible strand of connective tissue that holds bones together is a ligament. Ligaments allow movement, and are found at the end of bones. Some ligaments, such as the ones on your vertebrae, prevent too much movement of bones.


  Cartilage is a strong, flexible, and smooth connective tissue found at the end of bones. It allows bones to move smoothly across each other. The tip of your nose and your ears are soft and bendy because they contain only cartilage. Cartilage does not contain blood vessels.
