摘要: Publisher Summary This chapter discusses ectopic cartilage, neoplasia, and metaplasia. To pronounce a tissue of an individual as out its rightful place requires thorough knowledge anatomy variations. Thus, cartilage is expected in the tongue dog but not that human. Cartilage occurring separately from principal skeleton, ear, airway normal part particular species called extraskeletal, distinction to (EC) which usually found at site any member species.

In unexpected late development, new growth, when it limited scarcely neoplasm. Many cartilage-bearing soft-tissue lesions are neoplastic. concepts metaplasia neoplasia pathological experimental cartilage. Most apparently forms by specialized cells. Its variety rarity pathology limitations scope experimentation have hampered exact elucidation genesis. Remedies will come more chemical immunologic identification cells, products, receptors, agents; use agents block induction cell; attention many potentially chondrogenic cells circumstances pointed human medicine comparative anatomy; guidance veterinary on suitable animals better exploit presently bewildering differences.
