megakaryocyten.

Brit.

/ˌmɛɡəˈkarɪə(ʊ)sʌɪt/, U.S.

/ˌmɛɡəˈkɛrioʊˌsaɪt/,

/ˌmɛɡəˈkɛriəˌsaɪt/

Forms: 1800s– megakaryocyte, 1900s– megacaryocyte.

Origin: Formed within English, by compounding. Etymons: mega- comb. form, karyo- comb. form, -cyte comb. form.

Etymology: < mega- comb. form + karyo- comb. form + -cyte comb. form; apparently coined by W. H. Howell (see quot. 1890 at main sense). Compare polykaryocyte n.

Physiology.

A giant cell with a large, irregularly lobed, polyploid nucleus, which occurs in small numbers in normal bone marrow and gives rise to blood platelets by fragmentation of its cytoplasm.
