What are perforating canals?
Canals in the bone in which blood vessels pass. Blood vessels from outside the bone penetrate the compact bone to the spongy bone through the PERFORATING CANALS.
What is the Horizontal canal in an osteon?
The perforating (Volkmann) canals, that run horizontally in compact bone and connect to the central canal.
What route is taken by nutrients through a bone starting with periosteum and ending with an osteocyte in a lacuna?
The circulatory system brings blood containing nutrients and oxygen to the periosteum, which covers the bone. The periosteum is a thin membrane that contains nerves and blood vessels. Its main function is to provide nourishment to the bone. From the periosteum, nutrients and oxybgen go through the perforating canals to the central canal, and then to the canaliculi. The osteocyte nearest the central canal passes nutrients to the next osteocyte with arm-like extensions that extend into the canaliculi to the next osteocyte. At the terminal end of each extension, gap junctions connect the cytoplasm of each osteocyte so that nutrients/wastes can be passed between cells to/from the central canal.
Compact bone has perforating and central canals why isn't a canal system necessary in spongy bones?
For a bone (or anything else) to be spongy, it has to have vast numbers of tiny gaps, holes, or what are in effect tiny canals. One large canal can be replaced by lots of smaller ones.
What is the central cavity of the labyrinth connecting the cochlea and the semicircular canals?
vestibule
Blood is distributed from the surface of a bone to deeper central canals through channels known as?
Other passageways, known as perforating canals or Volkmann's canals, extend perpendicular to the surface. Blood vessels in these canals supple blood to osteons deeper in the bone and to tissues of the medullary cavity.

Which structures allow communication between blood vessels and nerves in the periosteum and endosteum?
Perforating (Volkmann's ) canals.
The periosteum a connective tissue covering on the diaphysis is represented by?
perforating (Sharpey's) fibers
What connects the central canals of osteons?
The cement line is what connects the central canals. They are made up of different layers of compact bone tissue.
Which structures are found inside the central canal?
If Audiology, continue.Associated with the inner ear, are the circulatory canals upon which we depend for balance.There are three of them, (yaw, pitch, roll) and each contains a tiny bone-like material, an otolith which rests on a bed of nerves, and which signals the state of balance. The otolith is composed of calcium and gel.The canals are fluid filled, and it is residual rotation, or recovery from pressure, that give us our dizziness.
Does spongy bone genrally have central canals?
No, the canals are present in the compact bone (surrounds the spongy bone) and are called Haversian canals.
What invention made canals less important?
Central product
