Haversian Canals

No, an osteon is the unit of compact bone containing what is known as Haversian canals (series of tubes surrounding and containing the blood vessels and nerve cells that satisfy compact bone)
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.
The Haversian canals carry blood vessels and nerves to and from the bone.
Volkmann's canals are nerves that run across the surface of the bone.
Osteonic canals contain blood vessels that connect to the long axis of the bone. The blood vessels that are connected perforate the canals of the bone and provide vessels to the surface of the bone which makes the bone hard.
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.
There is oxygenated blood in the efferent capillaries.

Haversian canals
The sclera.
All bones have foramen in them. These are canals or openings through which nerves and blood vessels go.
Blood vessels in these canals supply blood to osteons deeper in the bone and to tissues of the medullary cavity.
