/ˈmɛkl/, U.S.

/ˈmɛk(ə)l/

Origin: From a proper name. Etymon: proper name Meckel.

Etymology: < the name of Johann Friedrich Meckel the younger (1781–1833), German anatomist (grandson of J. F. Meckel the elder: see Meckel's ganglion n.). Compare Meckelian adj. With Meckel's cartilage compare Meckelian cartilage n. at Meckelian adj. 1a and its German model Meckelscher Knorpel.

a. Anatomy and Pathology Meckel's diverticulum n. a diverticulum of the distal ileum, typically about 5 cm (2 inches) in length and located about one metre from the ileocaecal valve, present as a remnant of the proximal vitelline duct in some 3 per cent of individuals; an individual instance of this; (also) this structure regarded as a pathological condition (usually as the site of inflammation or haemorrhage).

1859 T. H. Huxley in Proc. Royal Soc. 9 396 The long distal division [of the mandibular cartilage] is termed, from the name of its original discoverer, Meckel's cartilage.

1910 Encycl. Brit. XIV. 259/1 The lower portion of the mandibular arch becomes greatly thickened to support the lower or hinder edge of the mouth. It forms the primitive lower jaw or ‘Meckel's cartilage’.

1930 H. G. Newth Marshall & Hurst's Junior Course Pract. Zool. (ed. 11) 421 The articular is continuous in front with Meckel's cartilage..which persists, even in the adult [fowl], along the greater part of the length of the mandible, ensheathed in membrane-bones.

1963 P. H. Greenwood Norman's Hist. Fishes (ed. 2) vi. 90 The earliest fish-like vertebrates possessed a series of these arches... The first pair was transformed into biting jaws, consisting of an upper portion known as the pterygo-quadrate cartilage, and a lower portion known as Meckel's cartilage.

1999 Jrnl. Anat. 194 265 It is widely accepted that Meckel's cartilage in mammals is uncalcified hyaline cartilage that is resorbed and is not involved in bone formation of the mandible.
