What is in the bone matrix?
- A.
Elastic fibers
- B.
Collagen fibers
- C.
Dense regular connective tissue
- D.
Reticular fibers
Correct Answer
B. Collagen fibersExplanation
The matrix of bone is mineralized. Within the matrix are collagen fibers and proteoglycans. Elastic fibers and reticular fibers are types of fibers seen in connective tissue. However, collagen fibers are the fibers found in bone. Although bone is classified as connective tissue, it is not classified nor is it composed of dense irregular connective tissue. Dense irregular tissue is seen in the dermis. Bone is not classified nor is it composed of dense regular connective tissue. Dense regular connective tissue is seen in tendons and ligamentsRate this question:

A. CanaliculiExplanation
Canaliculi are the little tunnels within the bone. Sharpey's fibers are collagen fibers that extend into a bone at an angle. Trabeculae are the spicules seen with spongy bone.

What is the hollow area underneath an osteoclast called?
- A.
Space of Disse
- B.
Space of Mall
- C.
Vacuole
- D.
Howship's lacuna
Correct Answer
D. Howship's lacunaExplanation
The space of Disse is in the liver. The space of Disse is also called the perisinusoidal space. It is the space between the liver sinusoids and the hepatocytes.
The space of Mall is also in the liver. The space of Mall is located at the portal canal and is the region between the connective tissue and the liver parenchymal cells. It is the site where lymph is formed within the liver.
A vacuole is a small clear space within an individual cell.
A lacuna is a small space or depression. The space that the chondrocyte rests in is a lacuna.
Howship's lacuna is seen in bone. Howship's lacuna is a space seen underneath an osteoclast.Rate this question:
