What is the purpose of Haversian canals?
Haversian canals are a series of tubes around narrow channels formed by lamellae. The Haversian canals surround blood vessels and nerve fibers throughout the bone and communicate with osteocytes.
What is the purpose of haversian and Volkmann’s canals?
Haversian canals typically run parallel to the surface and along the long axis of the bone and generally contain one or two capillaries and nerve fibers. Volkmann’s canals are channels that assist with blood and nerve supply from the periosteum to the Haversian canal.
What is the purpose of the lacunae?
Lacunae – Function The primary function of lacuna in bone or cartilage is to provide housing to the cells it contains and keeps the enclosed cells alive and functional. In bones, lacunae encase osteocytes; in cartilage, lacunae enclose chondrocytes.
What is the purpose of the medullary cavity?
However, the medullary cavity is the area inside any bone (long, flat, etc.) that holds the bone marrow. This area is involved in the formation of red blood cells and white blood cells, and the calcium supply for bird eggshells. The area has been detected in fossil bones despite the fossilization process.
What is the purpose of this canal in the diaphysis?
The canals contain capillaries that bring in oxygen and nutrients and remove wastes.

What is a medullary canal?

Which of the following are functions of osteocytes?
The potential functions of osteocytes include: to respond to mechanical strain and to send signals of bone formation or bone resorption to the bone surface, to modify their microenvironment, and to regulate both local and systemic mineral homeostasis.
What is the purpose of the diaphysis of a bone quizlet?
-Main shaft of longbone; hollow, cylindrical shape, thick, compact bone. Function: Provide strong support without cumbersome weight.
