Premineralization.
spongy bone has samall open spaces that make bones lightweight
It's called 'Bone Marrow' - Bone marrow is the flexible tissue found in the hollow interior of bones. In adults, the marrow in the larger bones produces new blood cells.
Cranial bones contain air spaces. These air spaces are known as skeletal pneumaticity. Bird bones are all filled with air spaces.
Compact bone is the type of bone tissue without visible open spaces. In contrast, spongy bone has visible spaces.

Cranial bones contain air spaces. These air spaces are known as skeletal pneumaticity. Bird bones are all filled with air spaces.
The compact bone is the outer part of the bone, and on the inside is the spongy bone. The spongy bone has small spaces which are filled with red bone marrow and some fat.
Spongy bone provides lightweight support. Consists of hardened fibers interspersed with many spaces. Skeletal system made of calcium hardened collagen fibers that make it strong but flexible.
Birds are very lightweight boned animals. :)
Trabecular bone.
The spongy bone is strong but lightweight.
