The tiny canals that connect the lacunae are the canaliculi, the larger canals are the Haversian canals.

The canaliculi are the tiny canals.
Spider-shaped mature bone cells, called OSTEOCYTES, live in small spaces in the lamellae called LACUNAE. Tiny canals, called CANALICULI, connect the lacunae to each other and to the Haversian canal. The canaliculi contain slender, tentacle-like cellular processes of the osteocytes. The canaliculi provide routes through which nutrients and oxygen from the blood can reach the osteocytes and waste products (ammonia, carbon dioxide) can be removed and eventually carried away by blood vessels in theHaversian canals.
They help to maintain balance of your body.
For a bone (or anything else) to be spongy, it has to have vast numbers of tiny gaps, holes, or what are in effect tiny canals. One large canal can be replaced by lots of smaller ones.
E. Trabeculae Well, Trabeculae translates to tiny beam or rod whereas trabeculae means tiny plates... and if it is for spongy bone, then that would be A. interstitial lamellae
Haversian canals .. Any of the tiny, interconnecting, longitudinal channels in bone tissue through which blood vessels, nerve fibers, and lymphatics pass.
They are three tiny, fluid-filled tubes in your inner ear and they help you keep your balance. When you move your head around, the liquid inside the canals kind of slosh and move around the tiny hairs that line the canals. Then these hairs basically tell what the movement is and send it to your brain. Your brain can then tell your body how to stay balanced. If you spin around and then stop, the liquid inside your canals move awhile longer and the hairs continue to send the message that you're spinning even though you're not. That's why after you get off an amusement park ride, you may still feel dizzy.
They are call synapses, there are two types chemical and electrical.
They are involved in helping with maintaining balance both when staying still and while in motion.
Your semicircular canals are three tiny, fluid-filled tubes in your inner ear that help you keep your balance. When your head moves around, the liquid inside the semicircular canals sloshes around and moves the tiny hairs that line each canal. These hairs translate the movement of the liquid into nerve messages that are sent to your brain. Your brain then can tell your body how to stay balanced. If you spin around and then stop, the liquid inside your semicircular canals moves awhile longer and the hairs continue to send the message that you are spinning even though you're not. That's why you feel dizzy after carnival or amusement park rides. Whoa!
The Middle Ear has a set of three loops of tube on planes roughly perpendicular to each other: the Semicircular Canals. Within these are nerve-endings fitted with tiny hairs, all submerged in a fluid that fills the Canals. As we move, the fluid moves, wafting the hairs to stimulate signals sent to the brain for processing into compensating-movement orders to the muscles. The Semi-circular Canals are therefore combined accelerometers and inclinometers, in a feedback control system.
Your balance and equilibrium. Each of the canals lie in a different plane and depending on which way you bend, twist, or turn, the fluid inside of them will trigger tiny hairs that signal what your orientation is so you can make moves to correct it and not wind up on the floor. That's also why spinning in circles makes you dizzy. It gets the fluid within those canals spinning as well and throws off your balance so you can't stand up. Fun huh?
