What is the histology of compact bone?

What is the histology of compact bone?

Mature compact bone is lamellar, or layered, in structure. It is permeated by an elaborate system of interconnecting vascular canals, the haversian systems, which contain the blood supply for the osteocytes; the bone is arranged in concentric layers around those canals, forming structural units called osteons.

What are bone cavities called?

FMA. 83698. Anatomical terminology. The medullary cavity (medulla, innermost part) is the central cavity of bone shafts where red bone marrow and/or yellow bone marrow (adipose tissue) is stored; hence, the medullary cavity is also known as the marrow cavity.

What is spongy bone called?

Cancellous bone, also called trabecular bone or spongy bone, light, porous bone enclosing numerous large spaces that give a honeycombed or spongy appearance.

What is long bone called?

Long bones are hard, dense bones that provide strength, structure, and mobility. The thigh bone (femur) is a long bone. A long bone has a shaft and two ends. Some bones in the fingers are classified as long bones, even though they are short in length.

What is Osteon?

Osteon (Haversian canal) Osteons are cylindrical vascular tunnels formed by an osteoclast-rich tissue. They contain pluripotential precursor cells and endosteum known as the cutting cone. The bone removed by the cutting cone is replaced by osteoblast-rich tissue.

What are the four parts of an Osteon?

Terms in this set (10)

• Osteon. A basic unit of structure in compact bone.
• Lamellae. Plates of collagen fiber.
• Collagen. Major component in connective tissue.
• Periosteum. A specialized connective tissue covering all bones.
• Spongy bone. Trebeculae, lattice like structures.
• Volkmann’s canal.
• Haverisian (central) canal.
• Lacunae.

What is inside an Osteon?

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. Each osteon consists of lamellae, which are layers of compact matrix that surround a central canal called the Haversian canal.

How is a secondary Osteon formed?

Secondary osteons differ from primary osteons in that secondary osteons are formed by replacement of existing bone. Secondary bone results from a process known as remodeling. In remodeling, bone cells known as osteoclasts first resorb or eat away a section of bone in a tunnel called a cutting cone.

Can bone tissue regenerate?

Bone possesses the intrinsic capacity for regeneration as part of the repair process in response to injury, as well as during skeletal development or continuous remodelling throughout adult life [1, 2].

How do you improve bone tissue?

What does a healing bone feel like?

The pain may feel like a sharp, stabbing pain. The pain also worsens if pressure is placed on it. As your bone heals, this decreases. If you have a cast placed around the area, you will likely feel almost no pain anymore because the bone is stabilized.
