Bones and skeleton
We each have a skeleton to support our softer organs and tissues, but that’s not all it does. By transmitting force and providing leverage, our skeleton allows us to move. Browse our gallery of 11 images of bones and skeletons to get closer to what’s inside all of us.

Growing bone
|
IMAGE 5 of 11
|
A region of growth (epiphyseal growth plate) in an immature thighbone. Cartilage is stained purple, and bone is stained yellow-green. The rapidly dividing cartilage cells within the purple band at the top form stacks that run parallel to the long axis of the bone. Below this zone, the cartilage becomes calcified and the cartilage cells (chondrocytes) die. Further down is the ossification zone, where the bone tissue is laid down.

The epiphysis

|
The ‘epiphysis’ is the rounded end of a long bone - the region of bone that forms joints with adjacent bones. The process seen here is ossification, the growth process that results in the generation of new bone. Calcification occurs during ossification.

Compact bone

IMAGE 7 of 11
|
Compact bone, from human femur. Transverse sections showing cross-sections and the arrangement of osteons and Haversian canals. Bone is made up of two types of tissue: the compact bone forms a shell around the spongy cancellous bone that makes up the marrow space in the centre. Compact bone provides strength and rigidity and is solid in appearance. It is composed of a layered matrix of organic substances and inorganic salts that form around an intricate network of vasculature called Haversian canals.
