Definitions:

Perforating Canals

Perforating canals, also known as Volkmann's canals, are channels within compact bone that allow blood vessels, lymph vessels, and nerves to travel across bone, connecting with Haversian canals.

Lamellar Canals

Small channels found in bone tissue that contain blood vessels and nerves, part of the bone's nutrient delivery system.

Osteochondral Canals

Osteochondral canals are channels within bone and cartilage that allow for the passage of blood vessels and nerves.

Canaliculi

Small, narrow channels within the bone structure that allow for communication and nutrient/waste exchange between osteocytes.
