Osmotic Fragility
|
D009996 |
[RED BLOOD CELL sensitivity to change in OSMOTIC PRESSURE. When exposed to a hypotonic concentration of sodium in a solution, red cells take in more water, swell until the capacity of the cell membrane is exceeded, and burst.

Osmotic Pressure
|
D009997 |
[A sudden change in the osmotic pressure caused by a large increase in the concentration of solution to which a cell is exposed, usually in order to cause it to shrink in CELL VOLUME.
, A change in the osmotic pressure caused by a dilution in the concentration of solution to which a cell is exposed.
, A change in the osmotic pressure caused by a change in the concentration of solution to which a cell is exposed.
, A sudden change in the osmotic pressure caused by a large change in the concentration of solution to which a cell is exposed, usually in order to cause it to burst and lose its contents.
, A change in the osmotic pressure caused by an increase in the concentration of solution to which a cell is exposed.
, A sudden change in the osmotic pressure caused by a large dilution in the concentration of solution to which a cell is exposed, usually in order to cause it to burst and lose its contents.
, The pressure required to prevent the passage of solvent through a semipermeable membrane that separates a pure solvent from a solution of the solvent and solute or that separates different concentrations of a solution. It is proportional to the osmolality of the solution.

Osseointegration
|
D016348 |
[The growth action of bone tissue as it assimilates surgically implanted devices or prostheses to be used as either replacement parts (e.g., hip) or as anchors (e.g., endosseous dental implants).
] |
|
Ossicular Prosthesis
|
D009998 |
[An implant used to replace one or more of the ear ossicles. They are usually made of plastic, Gelfoam, ceramic, or stainless steel.
] |
|
Ossicular Replacement
|
D019933 |
[Surgical insertion of an implant to replace one or more of the ear ossicles.

|
Ossification of Posterior Longitudinal Ligament
|
D017887 |
[A calcification of the posterior longitudinal ligament of the spinal column, usually at the level of the cervical spine. It is often associated with anterior ankylosing hyperostosis.
] |
|
Ossification, Heterotopic
|
D009999 |
[The development of bony substance in normally soft structures.
] |
|
Osteitis
|
D010000 |
[Inflammation of the bone.
] |
|
Osteitis Deformans
|
D010001 |
[A disease marked by repeated episodes of increased bone resorption followed by excessive attempts at repair, resulting in weakened, deformed bones of increased mass. The resultant architecture of the bone assumes a mosaic pattern in which the fibers take on a haphazard pattern instead of the normal parallel symmetry.

|
Osteitis Fibrosa Cystica
|
D010002 |
[A fibrous degeneration, cyst formation, and the presence of fibrous nodules in bone, usually due to HYPERPARATHYROIDISM.
] |
|
Osteoarthritis
|
D010003 |
[A progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. The disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. In the foreign literature it is often called osteoarthrosis deformans.
] |
|
Osteoarthritis, Hip
|
D015207 |
[Noninflammatory degenerative disease of the hip joint which usually appears in late middle or old age. It is characterized by growth or maturational disturbances in the femoral neck and head, as well as acetabular dysplasia. A dominant symptom is pain on weight-bearing or motion.
] |
|
Osteoarthritis, Knee
|
D020370 |
[Noninflammatory degenerative disease of the knee joint consisting of three large categories: conditions that block normal synchronous movement, conditions that produce abnormal pathways of motion, and conditions that cause stress concentration resulting in changes to articular cartilage. (Crenshaw, Campbell's Operative Orthopaedics, 8th ed, p2019)
] |
|
Osteoarthritis, Spine
|
D055013 |
[A degenerative joint disease involving the SPINE. It is characterized by progressive deterioration of the spinal articular cartilage (CARTILAGE, ARTICULAR), usually with hardening of the subchondral bone and outgrowth of bone spurs (OSTEOPHYTE).
] |
|
Osteoarthropathy, Primary Hypertrophic
|
D010004 |
[A condition chiefly characterized by thickening of the skin of the head and distal extremities, deep folds and furrows of the skin of the forehead, cheeks, and scalp, SEBORRHEA; HYPERHIDROSIS; periostosis of the long bones, digital clubbing, and spadelike enlargement of the hands and feet. It is more prevalent in the male, and is usually first evident during adolescence. Inheritance is primarily autosomal recessive, but an autosomal dominant form exists.
] |
|
Osteoarthropathy, Secondary Hypertrophic
|
D010005 |
[Symmetrical osteitis of the four limbs, chiefly localized to the phalanges and the terminal epiphyses of the long bones of the forearm and leg, sometimes extending to the proximal ends of the limbs and the flat bones, and accompanied by dorsal kyphosis and joint involvement. It is often secondary to chronic conditions of the lungs and heart. (Dorland, 27th ed)

|
Osteoblastoma
|
D018215 |
[A benign, painful, tumor of bone characterized by the formation of osteoid tissue, primitive bone and calcified tissue. It occurs frequently in the spine of young persons. (From Dorland, 27th ed; Stedman, 25th ed)

|
Osteoblasts
|
D010006 |
[Bone-forming cells which secrete an EXTRACELLULAR MATRIX. HYDROXYAPATITE crystals are then deposited into the matrix to form bone.
] |
|
Osteocalcin
|
D015675 |
[Vitamin K-dependent calcium-binding protein synthesized by OSTEOBLASTS and found primarily in BONES. Serum osteocalcin measurements provide a noninvasive specific marker of bone metabolism. The protein contains three residues of the amino acid gamma-carboxyglutamic acid (Gla), which, in the presence of CALCIUM, promotes binding to HYDROXYAPATITE and subsequent accumulation in BONE MATRIX.

D010007 |
[Inflammation of a bone and its overlaying CARTILAGE.
