Final answer:
Osteocytes are found in lacunae, which are connected by canaliculi. These structures facilitate nutrient and waste exchange with the blood vessels in the Haversian canal.
Step-by-step explanation:
The osteocytes, which are the most abundant cells in bone tissue, are located inside spaces called lacunae (singular = lacuna). These bone-forming cells become entrapped in these small chambers during the process of bone matrix formation and calcification. Lacunae are found at the borders of adjacent lamellae, and they do not stand alone. Each lacuna is connected to the network of other lacunae via tiny canals called canaliculi. This network facilitates the exchange of nutrients and waste between the osteocytes and the blood vessels that run through the central canal, also known as the Haversian canal, which is the core of the structural unit of compact bone known as an osteon or Haversian system.
In summary, the correct answer to the question 'Osteocytes are located in minute bone chambers called:' is b) Lacunae.
