myofibriln.

Brit.

/ˌmʌɪə(ʊ)ˈfʌɪbrɪl/,

/ˌmʌɪə(ʊ)ˈfɪbrɪl/, U.S.

/ˌmaɪoʊˈfaɪbr(ə)l/

Origin: Formed within English, by compounding. Etymons: myo- comb. form, fibril n.

Etymology: < myo- comb. form + fibril n. Compare German Muskelfibrille (1882 in Zool. Anzeiger 5 361), Myofibrille (S. Apáthy 1897, in Mittheilungen aus der Zoologischen Station zu Neapel 12 506). Compare also neurofibril n. (see especially quot. 1898).Quot. 1898 is an account of the 1897German paper cited above.

Histology and Physiology.

Any of the numerous longitudinal contractile structures, each about one to two micrometres in diameter, that occupy the cytoplasm of a myofibre.

1898 Jrnl. Royal Microsc. Soc. 64 The muscle-cell produces conducting substance (myofibrils).

1910 Amer. Naturalist 44 197 The myotomes..are composed of many perfect muscle fibers with the myofibrils developed in several bundles in the peripheral cytoplasm.

1933 Physiol. Rev. 13 318 Thus far it has been assumed that myofibrils are actual morphologic entities.

1960 G. H. Bourne Struct. & Function Muscle I. ii. 34 Microdissection of fresh muscle fibers as a means of demonstrating myofibrils is exceedingly difficult.

1995 Farmers Weekly 31 Mar. 48/4 Meat quality [was] measured for toughness by compression test, myofibril fragmentation (a measure of physical breakdown) and intramuscular marbling fat.
