  eMedicine - Skeletal Dysplasia : Article by Harold Chen, MD, MS, FAAP, FACMG
Skeletal dysplasias are a heterogeneous group of more than 200 disorders characterized by abnormalities of cartilage and bone growth resulting in abnormal shape and size of the skeleton and disproportion of the long bones, spine, and head.
Skeletal dysplasia is a heterogeneous group of disorders characterized by abnormalities of cartilage and bone growth.

 SKELETAL DISEASES OF GROWING DOGS
The vast majority of developmental skeletal disorders diagnosed in veterinary practice occur in large and giant breeds and are associated with excess (i.e., inappropriate) intake of a commercial diet and/or supplementation.
Rapid velocity of growth in large and giant breeds increases their risk of skeletal disease.(7,13) Excess energy per se in an otherwise balanced diet is not a direct contributor to skeletal disease in the growing dog(8,19); the link appears to occur when energy contributes to rapid growth rates and excessive body weight.
A study by Nap and coworkers reported on the role of protein in disturbances of skeletal development(21,22): Three groups of Great Dane puppies were fed three levels of protein (31.6%, 23.1%, and 14.6% on a dry matter basis) in an isoenergetic dry dog food from 7 weeks through 18 weeks of age.

  Skeletal fluorosis is a crippling bone disease caused by fluoride
Skeletal fluorosis is characterized by hyperostosis, osteopetrosis, and osteoporosis (Obel, 1971; Shupe, 1980).
Advanced stages of skeletal fluorosis are associated with intakes of fluoride ranging from 20 to 80 mg/day for 10 or more years (Hodge and Smith 1977, WHO 1984)." The quotes may be accurate but the statements are false.
The difficulties in diagnosing skeletal fluorosis result from the questionable sensitivity of the x-ray techniques and from the non-specificity of the associated symptoms.

  Skeletal muscle Summary
Skeletal muscles are used to facilitate movement, by applying force to bones and joints; via contraction.
Skeletal muscles usually have one end (the "origin") attached to a relatively stationary bone, (such as the scapula) and the other end (the "insertion") is attached across a joint, to another bone (such as the humerus).
Skeletal muscle cells are stimulated by acetylcholine, which is released at neuromuscular junctions by motor neurons.

Skeletal fluorosis is a well-known public health problem in several naturally fluoridated areas of the world.
Endemic bent knee is observed primarily in young and adolescent boys and is characterized by: simultaneous osteomalacia; osteosclerosis; and osteoporosis with secondary hyperparathyroidism.
Production of skeletal fluorosis is influenced not only by the fluoride content of the water supplies, but also by that of food and beverages, by industrial gaseous or particulate emissions of fluoride, by the calcium and magnesium intake, and by the efficiency of the kidney function.

Skeletal fluorosis is a bone disease caused by excessive consumption of fluoride.
Common causes of fluorosis include: inhalation of fluoride dusts/fumes by workers in industry, use of coal as an indoor fuel source (a common practice in China), and consumption of fluoride from drinking water.
In the United States, an average of 1 ppm of fluoride is purposely added to water supplies for water fluoridation, while the Maximum Contaminant Level (as established by the US Environmental Protection Agency) is 4 ppm.

 Gallery of skeletal carbonate images
The skeletal parts of organisms are commonly composed of calcite, magnesian calcite, aragonite or opaline silica.
This mineralogy determines the susceptibility of the skeletal fragment to diagenetic change and so its current composition and fabric in a limestone or dolomite.
Skeletal grains of magnesian calcite, that is with 4-20 mole % magnesium in the calcite, include those produced by echinoderms, most foraminifera, and red algae.

 BioMed Central | Full text | Recurrence in skeletal muscle from squamous cell carcinoma of the uterine cervix: a case ...
The incidence of skeletal muscle metastases is reported to be less than 1% of metastases of haematogenous origin, despite the fact that skeletal muscle accounts for nearly 50% of the total body weight and is characterized by a rich blood supply [1].
As shown in Table 1, skeletal muscle involvement from cervical carcinoma is very rare, and usually documented in the context of an already far advanced stage tumor or metastatic disease [6-8], or in severely immunocompromised patients, as occurs in patients with AIDS [3,4].
Given the very rare occurrence of skeletal muscle metastasis, there are no specific guidelines on the therapeutic options, which include radiotherapy, chemotherapy and surgery according to the clinical setting: indeed, the real benefit of these approaches remains questionable given the very poor prognosis of these patients.

(Take a look at some skeletal muscle) (image from http://www.mds.qmw.ac.uk/biomed/kb/microanatomy/muscle_nerve/) This functional specialization of skeletal muscle is achieved through the process of terminal differentiation, in which cells withdraw from the cell cycle and specific genes are established (and expressed) to define cell identification and function.
