 Today we're going to talk about bone, which is a type of connective tissue, and bone is made up of osteocytes. So if you remember when we talked about other tissue types, we knew that the suffix cites meant cells, and so the prefix osteo just refers to bone. And so osteocytes are located in lacuna, and they have projections called canaliculi. So since bone is a connective tissue, it's laid down in a matrix. The matrix is made up of calcium salts. So we're going to take a look at an osteocyte. And so the osteocyte is here, this cell, and the lacuna is this outer space. So here it's notated LC for lacuna and O for osteocyte. And so you see these projections, and those are the canaliculi. And canaliculi is plural, canaliculus is singular. And so the one thing we've talked about before is that the blast cells build, so osteoblasts build bone. So you can remember blasts build bone and osteoclasts, the clasts break down a tissue. And so for this you can remember that they carve out bone. So osteoclasts carve out bone, and that's just a way to remember the difference between an osteoblast and an osteoclast.
