24 Απρ 2019 · Compact bone, also called cortical bone, surrounds spongy bone and makes up the other 80% of the bone in a human skeleton. It is smooth, hard and heavy compared to spongy bone and it is also white in appearance, in contrast to spongy bone which has a pink color.
Compact bones are present in the outer layer of long bones, while spongy bones are present in the middle of the long bones. The main difference between spongy and compact bones is their structure and function.
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function. Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution.
Compact bone is dense so that it can withstand compressive forces, while spongy bone (also called cancellous bone) has open spaces and is supportive, but also lightweight and can be readily remodeled to accommodate changing body needs.
20 Σεπ 2017 · The main difference between compact and spongy bone is that compact bone is the hard outer layers of the bone whereas spongy is the more porous, inner layers of the bone. Compact bones lack spaces between lamellae whereas spongy bones consist of spaces between lamellae.
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function. Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution.
Based on the nature of bone-matrix, the skeletal bones are classified into two categories – (1) Compact bones and (2) Spongy bones. (1) Compact bone: They are tough and heavy bones made of compactly packed osteons. They form the shaft or diaphysis of long bones. (2) Spongy bone: They are soft and light bones make up of loosely packed ...
