Osteonic Canals
True.
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.

Bone Tissue made up of Osteocytes.
The matrix for bone is laid down in thin layers called lamellae. The lamellae are arranged in concentric patterns around tubes called osteonic canals. Between the layers of lamellae the osteocytes are placed in depressions called lacunae. This pattern of concentric circles forms a cylinder-shaped unit called the osteon.
Both of these are in the ear. The semi-circular canals help you to balance and the cochlea transmits nerve signals to the brain. This is how you hear. The inner ear is subdivided into the vestibule, semicircular canals, and cochlea. The semicircular canals and cochlea are separate structures with different functions. The receptors for balance are in the semicircular canals, and the organ of Corti (the organ of hearing) is in the cochlea.
