Question

Volkmann's canal connects
A. osteocyte with matrix
B. different bone
C. haversian canal with matrix
D. haversian canal with other haversian canals

Answer 1

Hint: Bone consists of various types of cells like osteoblast(bone forming cells),osteoclasts(bone destroying cells) matrix inorganic material salts,nerves blood vessels and cartilage. They are present inside the bone(osteon).

Complete Answer:
- The Haversian canal allows blood vessels and nerves to pass through them and are located inside the bone. There are many haversian canals and are present in spaces called lacunae connected by canaliculi.
- They run parallel to the longitudinal axis of bone. Volkmann's canals interconnect the two haversian canals with each other.
- They are the peculiarity of mammalian bone and are small channels that facilitate transport and communicate with the haversian canals. They also allow blood vessels and nerves to pass through them. They are named after volkmann alfred wilhelm.

Note: Haversian canal is also called as central canal. Spongy tissue also called as cancellous bone is found in the inside area of the bone and compact tissue is found on the outer side. Spongy bone contains osteocytes in lacunae(contains bone cells) but not in concentric layers. Volkmann's canals are the perforating ones or channels that are arranged in a coordinated way.
