Structural unit of compact bone consisting of a central canal, called the haversian canal, surrounded by a number of concentric rings of bony matrix called lamellae. channels lying at right angles to the central canal, connecting blood and nerve supply of the periosteum to that of the haversian canal.
Similarly, you may ask, what is found in the central canal of bone?
Each osteon consists of concentric layers, or lamellae, of compact bone tissue that surround a central canal, the haversian canal. The haversian canal contains the bone's blood supplies. The boundary of an osteon is the cement line.
What does the central canal do?
The central canal, also known as ependymal canal, is the cerebrospinal fluid-filled space that runs longitudinally through the length of the entire spinal cord. The central canal is continuous with the ventricular system of the brain.
What can be found in the central canal?
It is filled with cerebrospinal fluid, and lined by ciliated, columnar epithelium, outside of which is an encircling band of gelatinous substance, the substantia gelatinosa centralis (or central gelatinous substance of spinal cord).
