the vertebrate endo skeleton is composed of bone, cartilage, tendons and ligaments. Now, bones are made of basically cells in this very special hard extra cellular matrix that contains calcium. Now, as you can see, there are many different types of bones. Short bones, flat bones, structural bones. And we're going to take a look at long bones, you can see a long bone right here. And what's special about long bones is they have this mega larry cavity which is going to contain red and yellow bone marrow and that's going to be very important for the production of blood cells. Now there are some special cell types and bones that I want to mention and those are osteoblasts and jump out of the way here. Osteoclasts. Osteoblasts are going to form bone and osteoclasts are going to re absorb bone and these cells are going to be involved in blood blood calcium, homeostasis, the endocrine regulation of it through the hormones, parathyroid hormone and calcitonin. And if you want to know more about that, recommend you go check out our videos on the endocrine system with that. Let's go ahead and flip the page
