Soft tissue disorders are medical conditions affecting soft tissue. Soft tissue injuries are some of the most chronically painful and difficult conditions to treat because it is very difficult to see what is going on under the skin with the soft connective tissues, fascia, joints, muscles and tendons.
Ectomesenchyme plays a critical role in the formation of the hard and soft tissues of the head and neck, such as bones, muscles, teeth, and notably, the pharyngeal arches. References [ edit ]
An extracranial germ cell tumor (EGCT) occurs in the abnormal growth of germ cells in the gonads (testes or ovaries) and the areas other than the brain via tissue, lymphatic system, or circulatory system. The tumor can be benign or malignant (cancerous) by its growth rate.
An extraskeletal chondroma often manifests clinically as a nodular soft tissue mass that steadily enlarges without discomfort and may exist for varying lengths of time before diagnosis. [2] The fingers and toes are the most often affected areas. [3] The tumor is oval in shape and clearly defined; it rarely has a diameter more than 3 cm. [4]
Ectopic calcification is a pathologic deposition of calcium salts in tissues or bone growth in soft tissues.This can be a symptom of hyperphosphatemia.Formation of osseous tissue in soft tissues such as the lungs, eyes, arteries, or other organs is known as ectopic calcification, dystrophic calcification, or ectopic ossification.
Mesenchyme (/ ˈ m ɛ s ə n k aɪ m ˈ m iː z ən-/ [1]) is a type of loosely organized animal embryonic connective tissue of undifferentiated cells that give rise to most tissues, such as skin, blood or bone.
When symptomatic, they can cause pain and myelopathy by intra-spinal bleeding, bony expansion or extra-osseous extension into surround soft tissue or the posterior neural elements. [ 4 ] [ 6 ] [ 7 ] [ 8 ] Highly vascular (cavernous type) hemangiomas can produce neurologic deficits without prominent evidence of spinal cord compression.
A true endoskeleton is derived from mesodermal tissue. In three phyla of animals, Chordata, Echinodermata and Porifera (), endoskeletons of various complexity are found.An endoskeleton may function purely for structural support (as in the case of Porifera), but often also serves as an attachment site for muscles and a mechanism for transmitting muscular forces as in chordates and echinoderms ...
