Osteocytes

Mature bone cells.

Osteoblasts

Bone building cells.

Osteoclasts

Bone resorbing cells.

Epiphyseal Plate

Cartilage near the expanded end of bone that is converted into bone through ossification.

Periosteum

Vascular layer of fibrous connective tissue that covers the surface of bone and forms new bone tissue.

Synovial Fluid

Lubricant secreted by the synovial membrane found in joint capsules.

Skeletal Muscle

Voluntary muscle attached to bones by tendons that contracts to move bones.

Smooth Muscle

Involuntary muscle found in the walls of blood vessels.

Cardiac Muscle

Involuntary striated muscle found in the heart.

Osteomyelitis

Infectious bone disease caused by bacterial infection leading to inflammation and pain.

Tuberculosis of the Bone

Bacterial infection that spreads from the lungs to the bone, leading to pain and deformity.

Osteoporosis

Vitamin and mineral deficiency resulting in soft, malformed, and fragile bones.

Rickets

Condition in children where bones do not ossify properly, leading to soft and bendy bones.

Paget’s Disease

Overproduction of abnormal bone tissue that fractures easily, affecting areas such as the skull and pelvis.

Scoliosis

Abnormal lateral curvature of the spine, often diagnosed with physical exams and X-rays.

Kyphosis

Exaggerated posterior curve of the thoracic spine, often associated with osteoporosis.

Osteogenic Sarcoma

A type of bone cancer that arises in bony tissue, typically affecting the ends of long bones.
