1. Osseous tissue is primarily composed of osteoblasts, osteocytes, and osteoclasts.
2. The extracellular matrix of osseous tissue contains hydroxyapatite, which gives bones their hardness.
3. There are two types of osseous tissue: compact bone and spongy bone.
4. Osseous tissue plays a critical role in supporting the body, protecting vital organs, and enabling movement.
5. Bone remodeling in osseous tissue involves the continuous cycle of bone resorption by osteoclasts and formation by osteoblasts.
