Spongy bones

Which organs are supported by cartilage?

- And we get older bones fuse together
Axial skeleton
Central supporting axis of the body. Protects central nervous system
Skull rib stermuum spine coccyx
Skull
Protects the brain.
Vertebral column
Protectes the spinal cord. Supports skull and trunk. Allows movement. 33 bones
Invertebral disc
A cartilaginous pad between the bodies of two adjacent vertebrae
Joins vertebrae together
Enhances the spinal flexibility
Scoliosis
Lateral curvature. Exaggerated spinal curvature at the lower region of the vertebral column
Kyphosis
Hunchback
An exaggerated spinal curvature at the upper region of the vertebral column
Lordosis
Abnormal spinal curvature at the lower region of the vertebral column
Thoracic cage
Ribs and sternum . 12 pairs of rib bones
Intercostal muscles
Lies between each rib
Clavicle
The collorbone. Lateral end flat. Medial side round.
Upper limb
Humerous, radius, ulna
