These canalicles connect with a neighbor canalicles. Therefore the osteocytes may communicate with each other and form an extensive net inside the bone matrix. This net of canalicles is very important for the bone metabolism, The bone extracellular matrix is not permeable to the transit of gases and liquids and nutrients. Oxygen, water, hormones, nutrients and other molecules are conducted inside the canaliculi.<\/p>\n<p>The figure is of a small bone specimen specially prepared to demonstrate bone lacunae and canalicles. The specimen was placed in a solution of the dye Thionine red that difused into the lacunae of the osteocytes and of their canalicules.<br \/>\nWhat is seen in the image is the dye inside the lacunae inhabited by osteocyte cell bodies (larger arrows) and inside the <strong>canaliculi<\/strong> occupied by extensions of osteocytes (smaller arrows).<br \/>\n<\/div><\/div>\n<div class=\"su-column su-column-size-1-2\"><div class=\"su-column-inner su-u-clearfix su-u-trim\">\n<p><img decoding=\"async\" src=\" https:\/\/mol-en.icb.usp.br\/wp-content\/uploads\/7-7.jpg \" \/><\/p>\n<p>Section of a bone specimen that had been placed in thionine solution.
