lacunokanalikulární

Lacunokanalikulární refers to a characteristic microscopic structure found in bone tissue. It describes the combination of lacunae and canaliculi, which are integral components of the osteon, the basic structural unit of compact bone. Lacunae are small cavities within the bone matrix, and each lacuna is typically occupied by a single osteocyte, a mature bone cell. These osteocytes are responsible for maintaining the bone matrix. Radiating out from each lacuna are numerous tiny channels known as canaliculi. These canaliculi form a network that connects the lacunae to each other and also to the blood vessels located in the central Haversian canals. This intricate lacunokanalikulární system is crucial for the transport of nutrients and waste products to and from the osteocytes, ensuring their survival and the health of the bone tissue. It facilitates communication between osteocytes, allowing them to coordinate their activities. The presence and arrangement of lacunae and canaliculi are key features examined in histology to understand bone structure and function, and can be indicative of pathological changes in bone.
