    Study Notes

    Osteoclasts

    • Found in bone tissue
    • Function: Break down bone tissue for bone remodeling and calcium release

    Haversian Canals

    • Found within compact bone tissue
    • Connect together via Volkmann's canals
    • Contain blood vessels and nerves
    • Surrounded by concentric rings of lamellae (bone tissue)
    • Form the Haversian system, a key structure in compact bone

    Irregular Bone Trabeculae

    • Found specifically in spongy bone tissue, a type of bone tissue
    • Responsible for supporting the structure of spongy bone and provide space for bone marrow
