Question

a passageway connecting neighboring osteocytes in an osteon is a:
a lamella
b lacuna
c osteocanal
d canaliculus
e central canal

Explanation:

• Lamella: It is a thin layer of bone matrix in an osteon, not a passageway for osteocytes.
• Lacuna: It is a small cavity that houses an osteocyte, not a connecting passageway.
• Osteocanal: Not a standard anatomical term for the structure in question.
• Canaliculus: Small channels (canaliculi) connect neighboring osteocytes in an osteon, allowing for communication and nutrient/waste exchange.
• Central canal: It contains blood vessels and nerves in the osteon, not for connecting osteocytes.

Answer:

D. canaliculus
