Spongy Bone has more surface area, but it is weaker and not as dense as compact bone.
Compact Bone is the tough outer layer of bone while spongy bone is the porous bone where the red and yellow marrow is.
Spongy is softer bone, with holes in it. It is found inside the bone. It is lighter than compact bone.
Compact bone is generally on the outer edges of bone. it is composed of multiple osteon units that are bunched closely together like stacked logs and, thus, is good at bearing weight in the long direction. Spongy bone is generally on the inside of compact bone. Individual osteon-like struts (called trabeculae) branch in many directions and interconnect. Thus, there are spaces created where red marrow exists. This kind of bone is good at handling stress from multiple directions and is lighter weight.
Spongy bone can appear yellow because it has some fat in it, and it is possible to see small holes in spongy bone. Compact bone is usually white.
Also, spongy bone is not long (like the wrist) most irregular and flat bones are formed from spongy bone tissue. Compact bone is usually long (like a femur).
Compact bone tissue is hard with few open spaces & provides protection and support.Spongy bone tissue is porous with many open spaces
Compact bone is dense and forms the outer layer of bones, providing strength and support, while spongy bone is less dense and found inside bones, providing flexibility and shock absorption. Compact bone also contains Haversian canals for blood vessels and nerves, whereas spongy bone contains trabeculae, branching bony plates that add strength and reduce weight.
The functional units of compact bone are called osteons. These form concentric layers that are called central canals. The central canals usually run parallel to the length of the bone and carry nutrients. All osteons in compact bone are aligned exactly the same and therefore makes compact bone very strong (when stressed along the long axis of the bone). Compact bone is very dense compared to spongy bone. It is located in the middle (diaphysis) of long bones. It can also has yellow marrow, which is mostly adipose (fat) tissue storage.
Spongy bone (located at the ends or epiphysis) does not have osteons. There is instead a spread out network of fibers, making it much less dense, more flexible, and reduce the weight of the skeleton. Red marrow is located in this type of bone as well as yellow, depending on the location in the body. Red marrow is responsible for red blood cell production as well as other things.

Do all compact bones contain spongy and compact bone tissue?
Yes, all compact bones contain both spongy and compact bone tissue. The outer layer of compact bone provides strength and protection, while the inner spongy bone contains bone marrow and provides flexibility.
What are the two types of bone?
The two types of bone are compact bone and spongy bone. Compact bone is dense and forms the outer layer of bones, providing strength and protection. Spongy bone is less dense and found inside bones, providing structural support and flexibility.
Compare compact and spongy bone in macroscopic appearance structure and relative location?
Compact bone is dense and solid, while spongy bone is porous and contains trabeculae that give it a spongy appearance. Compact bone is typically found on the outer layer of bones, providing strength and support, while spongy bone is located deeper within bones and helps with shock absorption and bone marrow production.
What are two kinds of bone tissue?
Compact bone tissue is dense and provides structural support and protection for bones. Cancellous (spongy) bone tissue is less dense and has a porous structure, helping to reduce the overall weight of bones while still maintaining their strength.
How do the structural difference in compact bones and spongy bones relate to the locations and functions of these two type of bones?
Compact bones are dense and strong, located in the shafts of long bones for support and protection. Spongy bones have a porous structure with trabeculae, found at the ends of long bones and in the interior of flat bones, aiding in shock absorption and providing red bone marrow for blood cell production. The differences in structure reflect their specific roles in the body in terms of support, protection, and blood cell production.
Do flat bones consist of compact bones sandwiched between spongy bones?
No. Flat bones consist of spongy bone sandwiched between compact bone.
Are bones lightweight because of spongy or compact bone?
Spongy
What is between the two bones?
spongy and compact
What is the histology of compact and spongy bones?
lumellar
Do flat bones consist of compact bone sandwiched between spongy bone?
The compact bone surrounds the spongy bone and provides structure for the body.
Are compact bones the outside of the bone?
Yes compact is on the outside while spongy is on the inside.
Do all compact bones contain spongy and compact bone tissue?
Yes, all compact bones contain both spongy and compact bone tissue. The outer layer of compact bone provides strength and protection, while the inner spongy bone contains bone marrow and provides flexibility.
What are the compositions of the bones?
compact bone tissue and spongy bone tissue
What kind of tissue makes up the bones?
spongy and compact bone
What are the two types of bone?
The two types of bone are compact bone and spongy bone. Compact bone is dense and forms the outer layer of bones, providing strength and protection. Spongy bone is less dense and found inside bones, providing structural support and flexibility.
What are the three layers of bones?
bone marrow compact bone spongy bone
How does compact bone differ from spongy bone?
Although compact bone looks hard and solid, a microscope reveals that it is riddled with passageways that serve as conduits for nerves, blood vessels, and lymphatic vessels. Spongy bone looks like a poorly organized tissue. Spongy bone looks like Swiss cheese with the many holes presented.
