The function of some dermal bone is conserved throughout vertebrates, although there is variation in shape and in the number of bones in the skull roof and postcranial structures. In bony fish, dermal bone is found in the fin rays and scales. A special example of dermal bone is the clavicle. Some of the dermal bone functions regard ...
A number of diseases can cause bone pain, including the following: Endocrine, such as hyperparathyroidism, osteoporosis, kidney failure. [7]Gastrointestinal or systemic, such as celiac disease and non-celiac gluten sensitivity (both often occur without obvious digestive symptoms), inflammatory bowel disease (including Crohn's disease and ulcerative colitis).
Indirect fracture healing, the most common type of bone repair, [10] relies heavily on endochondral ossification. In this type of healing, endochondral ossification occurs within the fracture gap and external to the periosteum. In contrast, intramembranous ossification takes place directly beneath the periosteum, adjacent to the broken bone’s ...
The bones are derived from dermal bone and are part of the dermatocranium. In comparative anatomy , the term is applied to the whole dermatocranium. [ 1 ] In general anatomy, the roofing bones may refer specifically to the bones that form above and alongside the brain and neurocranium (i.e., excluding the marginal upper jaw bones such as the ...
Fibrodysplasia ossificans progressiva (/ ˌ f aɪ b r oʊ d ɪ ˈ s p l eɪ ʒ (i) ə ɒ ˈ s ɪ f ɪ k æ n z p r ə ˈ ɡ r ɛ s ɪ v ə /; [1] abbr. FOP), also called Münchmeyer disease or formerly myositis ossificans progressiva, is an extremely rare connective tissue disease in which fibrous connective tissue such as muscle, tendons, and ligaments turn into bone tissue (ossification).
They are characterized by interruption of the blood supply of a bone, in particular to the epiphysis, [1] followed by localized bony necrosis, [2] and later, regrowth of the bone. [3] This disorder is defined as a focal disturbance of endochondral ossification and is regarded as having a multifactorial cause, so no one thing accounts for all ...
Symptoms may include: [citation needed] Pain that may occur at the site of the tumor if the tumor is very large, or if the affected bone has weakened causing a fracture of the affected bone; Enlargement of the affected finger; Slow bone growth in the affected area; The symptoms of enchondroma may resemble other medical conditions or problems.
The dermatocranium is the portion of the cranium that is composed of dermal bone, as opposed to the endocranium and splanchnocranium, which are composed of endochondral bone. The dermatocranium comprises the skull roof, the facial skeleton (usually excluding the dentary), and—in fishes—the opercular bones. [1]
