What is bone histology?

Bone is a modified form of connective tissue which is made of extracellular matrix, cells and fibers. The high concentration of calcium and phosphate based minerals throughout the connective tissue is responsible for its hard calcified nature.

Why is bone histology important?

The best way to thoroughly observe the microarchitecture of bone is to perform undecalcified bone histology, which can reveal the mineralized and cellular components of the bone as well as patterns regarding the physiological processes of bone formation and resorption.

What is a bone in anatomy?

Bone is living tissue that makes up the body’s skeleton. There are 3 types of bone tissue, including the following: Compact tissue. The harder, outer tissue of bones. Cancellous tissue.

What is the histology of cartilage?

Cartilage is a connective tissue structure that is composed of a collagen and proteoglycan-rich matrix and a single cell type: the chondrocyte. Cartilage is unique among connective tissues in that it lacks blood vessels and nerves and receives its nutrition solely by diffusion [1].

What are the tubular bones?

Tubular bone – long tubular bones are bones of the extremities (e.g. femur, humerus); short tubular bones are bones of hands and feet. Irregular bone – bones of the face and vertebrae.

What is a bone easy definition?

A bone is a rigid tissue that constitutes part of the skeleton in most vertebrate animals. Bones protect the various organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility.

What is bone and classification of bone?

The bones of the body come in a variety of sizes and shapes. The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities.

What is blood histology?

Blood is composed of specialized cells that circulate in an extracellular fluid called plasma. The morphology and characteristics of blood cells can be analyzed histologically by using a common technique called a blood smear or blood film.

What is the histology of compact bone?

Compact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.

What is histology microscopic anatomy?

Histology is the study of the microscopic anatomy of cells and tissues of plants and animals. It is performed by examining a thin slice (section) of tissue under a light microscope or electron microscope. Each tissue is classified based on the location, shape, and function of the cells which comprise them.

Is histology and cytology the same?

Histology is the final analysis of the microscopic anatomy of cells and tissues whereas the cytology is the straightforward analysis of cells solely. Histology has additional explicit focus as compared with the cytology. Histology is looking at tissue samples and can usually decide what sort of tissue you are taking a look at.

Who is the father of histology?

Marie François Xavier Bichat (14 November 1771 – 22 July 1802) was a French anatomist and pathologist, known as the father of histology.

Histology of Compact Bone. Compact bone is also called dense bone. Compact bone is composed of closely packed osteons. An osteon is also called a Haversian system. An osteon is the cylindrical structure with bone.

What is the histology of the ureters?

Histology – Ureter Description: This is a transverse section through the ureter. Notice the transitional epithelium of the mucosal lining, the smooth muscle in the muscular middle layer, and the connective tissue external layer with numerous small blood vessels, many of which are filled with red blood cells.
