Bone Basics
This living tissue makes up the majority of each bone and constantly remodels itself.
Bone Tissue
Arm and leg bones fall into this category of bone shape.
Long bones
The expanded ends of long bones that form joints with adjacent bones.
Epiphyses
These bone cells live inside lacunae.
Osteocytes
These bone‑resorbing cells break down calcified matrix.
Osteoclasts
Along with bone, this supportive connective tissue helps form the skeletal system.
Cartilage
Bones of the wrist and ankle are examples of this nearly equal‑length bone type.
Short Bones
This hyaline cartilage covers the epiphyses.
Articular Cartilage
In compact bone, lacunae are arranged in concentric circles called this.
Lamellae
These bone‑building cells deposit new bone tissue.
Osteoblasts
This function of bone allows muscles to anchor and produce movement.
Attachment
Vertebrae and certain facial bones belong to this varied‑shaped bone group.
Irregular Bones
The shaft of a long bone is known by this name.
Diaphysis
These longitudinal channels contain blood vessels and nerve fibers.
Central Canals
This region of a long bone remains active during childhood and adolescence, allowing the bone to lengthen until it eventually ossifies.
Epiphyseal plate (growth plate)
This bone function protects organs like the brain and lungs.
Protection and Support
Ribs and scapulae are examples of this broad, plate‑like bone category.
Flat Bones
This hollow chamber inside the diaphysis houses marrow.
Medullary Cavity
This portion of bone matrix consists mainly of collagen and inorganic salts
Extracellular Matrix
Flat skull bones form through this type of ossification.
Intramembranous Ossification
Bones store large quantities of these, especially calcium phosphate.
Inorganic Salt
The patella is the classic example of this tendon‑embedded bone type.
Sesamoid Bone
This tough, fibrous outer covering of bone is continuous with ligaments and tendons.
Periosteum
Osteocytes exchange nutrients through these tiny canals.
Canaliculi
Most bones begin as hyaline cartilage models in this type of ossification.
Endochondral Ossification
