1- BASIC STRUCTURE OF BONE TISSUES

Bone tissues are made of a hard calcified matrix, and of osteocytes scattered in the matrix.
Click in the blue square. Osteocytes lie in little chambers: the lacunae.
A fine network of hairlike canals (= the canaliculi), radiate from each lacunae in all direction and connect these lacunae to each other. Canaliculi are filled with extracellular fluid and contain the fine cytoplasmic processes (= extensions) of the osteocytes: this allows the osteocytes to be connected to each other by their very fine tentacle-like cytoplasmic processes.
