the endosteum is a thin membrane that lines the internal surface while compact bone forms the outer shell of the bone(the part we see) and shafts in long bones e.g femur
The periosteum is the membrane around the shaft of a long bone.
Osteoclasts break down bone (osteo-=bone, -clast=breaks) and osteoblasts build bone. (-blast=builder). This osteoclasts is on the surface of the bone. Usually breaking down and building up of bone is in equilibrium.
It is the endosteum.
The medullary cavity is lined with endosteum, a connective tissue membrane that contains osteoprogenitor cells responsible for bone growth and repair. It helps to maintain the structural integrity of the bone and plays a role in bone remodeling.
Compact bone is dense and does not contain many spaces (unlike spongy bone). It has a concentric-ring structure. Compact bone consists of osteons which contains blood vessels and Volkmann's canals (which also hold blood vessels and nerves but run perpendicular to the osteons).
A long bone consists of: Periosteum, articular cartilage, medullary cavity, endosteum, cancellous bone, blood vessels, and compact bone.
The periosteum is a dense membrane of connective tissue that covers the outer surface of bones, while the endosteum is a thin layer of connective tissue that lines the inner surface of bones. The periosteum is involved in bone growth, repair, and nutrition, while the endosteum is involved in bone remodeling and repair.
This is endosteum.Endosteum.
Endosteum tissue lines the openings in spongy bone.
The compact bone surrounds the spongy bone and provides structure for the body.
The periosteum is the membrane around the shaft of a long bone.
Osteoclasts break down bone (osteo-=bone, -clast=breaks) and osteoblasts build bone. (-blast=builder). This osteoclasts is on the surface of the bone. Usually breaking down and building up of bone is in equilibrium.
The endosteum is a thin membrane that lines the inner surface of bones. Its main functions are to contribute to bone growth, repair, and remodeling by containing bone-forming cells called osteoblasts and bone-resorbing cells called osteoclasts. Additionally, the endosteum plays a role in regulating the transport of nutrients and waste products in and out of the bone.

The four main layers of bones are the periosteum (outer layer), compact bone (dense and hard layer), spongy bone (porous inner layer), and bone marrow (innermost layer responsible for blood cell production).
