Which tissues are components of a typical bone?

Which tissues are components of a typical bone?

Bone is a mineralized connective tissue that exhibits four types of cells: osteoblasts, bone lining cells, osteocytes, and osteoclasts [1, 2]. Bone exerts important functions in the body, such as locomotion, support and protection of soft tissues, calcium and phosphate storage, and harboring of bone marrow [3, 4].

What is the typical structure of a long bone?

A long bone has two parts: the diaphysis and the epiphysis. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow.

What are long bones composed of?

The outer shell of the long bone is compact bone, below which lies a deeper layer of cancellous bone (spongy bone), as shown in the following figure. The interior part of the long bone is called the medullary cavity; the inner core of the bone cavity is composed of marrow.

What type of bone tissue makes up the shaft of a long bone?

cortical bone

What are mature bone cells called?

osteocytes

What is spongy bone for?

Spongy bone reduces the density of bone and allows the ends of long bones to compress as the result of stresses applied to the bone. Spongy bone is prominent in areas of bones that are not heavily stressed or where stresses arrive from many directions.

What bone violates the laws of ossification?

Fibula

Where is endochondral ossification found?

Endochondral ossification is the process by which growing cartilage is systematically replaced by bone to form the growing skeleton. This process occurs at three main sites: the physis, the epiphysis, and the cuboidal bones of the carpus and tarsus.

What are the 3 types of tissue in bone?

There are 3 types of bone tissue, including the following:

• Compact tissue. The harder, outer tissue of bones.
• Cancellous tissue. The sponge-like tissue inside bones.
• Subchondral tissue. The smooth tissue at the ends of bones, which is covered with another type of tissue called cartilage.

What are the characteristics of bone tissue?

Bone is a specialized connective tissue consisting of cells, fibers and ground substance. Unlike other connective tissues, its extracellular components are mineralized giving it substantial strength and rigidity.
