scolex
sco·lex S0153100 (skō′lĕks′)n. pl. sco·li·ces (-lĭ-sēz′) The knoblike anterior end of a tapeworm, having suckers or hooklike parts that in the adult stage serve as organs of attachment to the host on which the tapeworm is parasitic.
[New Latin scōlēx, from Greek skōlēx, worm.]scolex (ˈskəʊlɛks) n, pl scoleces (skəʊˈliːsiːz) or scolices (ˈskɒlɪˌsiːz; ˈskəʊ-) (Zoology) the headlike part of a tapeworm, bearing hooks and suckers by which the animal is attached to the tissues of its host[C19: from New Latin, from Greek skōlēx worm]sco•lex (ˈskoʊ lɛks)
n., pl. sco•le•ces (skoʊˈli siz)
scol•i•ces (ˈskɒl əˌsiz, ˈskoʊ lə-) the frontal segment of a tapeworm, having suckers or hooks for attachment. [1850–55; < Greek skṓlēx worm] TranslationsScolex
scolex[′skō‚leks] (invertebrate zoology) The head of certain tapeworms, typically having a muscular pad with hooks, and two pairs of lateral suckers. Scolex the head or anterior portion of the body of a tapeworm, or cestode, by which the parasite attaches itself to the wall of the host’s intestine. The scolex may have any one of various organs of attachment: bothria (longitudinal slits of which there are generally two), sucking disks, and chitinized hooks. In highly developed tapeworms the scolex has four semispheric muscular sucking disks. Many cestodes are characterized by a scolex having sucking disks and a proboscis with hooks. The structure of a scolex, especially of the organs of attachment, is often used in taxonomy for species identification. scolex
scolex [sko´leks] (Gr.) the attachment organ (mouth) of a tapeworm, generally considered the anterior, or cephalic, end.sco·lex, pl. sco·le·ces, scol·i·ces (skō'leks, skō'le-sēz, skō'li-sēz), The head or anterior end of a tapeworm attached by suckers, and frequently by rostellar hooks, to the wall of the intestine; it is formed within the hydatid cyst in Echinococcus, within a cysticercus in Taenia, a cysticercoid in Hymenolepis, or by a plerocercoid, as in Diphyllobothrium latum. The form of the scolex varies greatly, the most familiar being rounded or club-shaped with four circular muscular suckers and an armed or unarmed rostellum, or a spatulate flattened scolex with a pair of slitlike suckers (bothria) and no rostellum, as in Diphyllobothrium and its allies. Other forms have complex leaflike, cup-shaped, or fimbriated shapes, or retractile, multiply spined proboscides. These varied forms characterize the orders of cestodes, which are particularly well developed as parasites of sharks and skates or rays.

[G. skōlēx, a worm]scolex The rounded head end of a tapeworm, bearing suckers or hooks by which it attaches itself to the intestine of the host. Fig. 275 Scolex . The scolex of Taenia solium. scolex the ‘head’ of a tapeworm, being that part at the anterior end which bears hooks and suckers and is used for attachment to the gut wall of the host. |
