Q. How are compact and spongy bone different?
Compact bone is dense and composed of osteons, while spongy bone is less dense and made up of trabeculae. Blood vessels and nerves enter the bone through the nutrient foramina to nourish and innervate bones.
Q. What is the difference between compact bone and spongy bone quizlet?
Compact bone has more bone matrix and less space due to osteons. Spongy bones have less bone matrix and more space due to trabeculae.
Q. What are two differences between cortical compact and trabecular spongy bone?
(2) Spongy bone: They are soft and light bones make up of loosely packed trabeculae. They form the epiphyses (bond ends) of long bones….Similarities between Compact bone and Spongy bone.
| Sl. No. | Compact (Cortical) Bone | Spongy (Cancellous) Bone |
|---|---|---|
| 5 | Made up of osteons | Made up of trabeculae |
Q. What are the thin plates forming spongy bone called?
Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.
Q. What are 3 types of bone cells?
Bone is composed of four different cell types; osteoblasts, osteocytes, osteoclasts and bone lining cells. Osteoblasts, bone lining cells and osteoclasts are present on bone surfaces and are derived from local mesenchymal cells called progenitor cells.
Q. What is the function of an Osteon?
It provides protection and strength to bones. Compact bone tissue consists of units called osteons or Haversian systems. Osteons are cylindrical structures that contain a mineral matrix and living osteocytes connected by canaliculi, which transport blood. They are aligned parallel to the long axis of the bone.
Q. What term best describes compact bone?
Compact bone, also called cortical bone, dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells.
Q. What is compact bone characterized by?
Compact bone forms the dense outer shell of bones. It has a smooth and homogeneous appearance. Compact bone is dense and solid in appearance, whereas cancellous (spongy) bone is characterized by open space partially filled with needle-like structures.
Q. What are the 4 classifications of bone?
The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones.
Q. Whats the difference between compact and spongy bone can be seen with the naked eye?
What differences between compact & spongy bone can be seen with the naked eye? Compact bone is very smooth, dense & thick. Spongy bone has a lot of open spaces.
