Periosteum
The purpose of the outer membrane of the bone is to cover and protect the interior bone (compact bone, spongy bone, and bone marrow.) Hope that helps!
The outer surface of the bone is called the periosteum.
The skin of the bone is called the periosteum
The outer layer of the bone marrow is called the periosteum, which is a dense fibrous membrane that covers the surface of bones.
The smaller outer leg bone below the knee is called the Tibia.
The tough outer covering of bone is called the periosteum. It is a dense connective tissue that protects the bone and plays a role in bone growth and repair.
the cranium
The outer part of the bone is called the cortex because it refers to the outer layer or shell of the bone structure, similar to how the term is used in other biological contexts, like the cortex of the brain. The cortex is primarily composed of dense, compact bone, providing strength and protection to the underlying structures. This outer layer plays a crucial role in supporting the overall integrity and function of the bone.
traphosphere
Insects have an 'exo-skeleton' or outer-skeleton - instead of an internal bone structure.
Periosteum is a membrane that lines the outer surface of all bones,[1] except at the joints of long bones.
the outer portionof most bones is a layer of hard compactbone called the "Cortex".
