conoid


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

co·noid

(kō'noyd),
1. A conic structure.
2. Part of the apical complex characteristic of the protozoan subphylum, Apicomplexa; seen in sporozoites, merozoites, or other developmental stages of sporozoans, less well developed in the piroplasms (families Babesiidae and Theileriidae). The function of the conoid is unknown, but it is thought to be an organelle of penetration into the host cell, possibly aided by a protrusible form of the conoid.

The authors found that the footprint of the conoid on the coracoid was 4.4 mm in the mediolateral plane and 9.6 mm in anteroposterior plane, and the footprint of the trapezoid was 5.7 mm by 15.2 mm, respectively.

The coracoclavicular ligaments consist of the trapezoid ligament laterally and conoid ligament medially.
As discussed in Anderson's article on distal clavicle fractures, (1) Rockwood revised the Neer type II clavicle fracture, in 1982, describing type IIA fracture as one in which both the conoid and trapezoid remain attached to the distal segment, and the type IIB fracture as one in which the conoid is torn.
By contrast, many parasites from the gamma irradiated tachyzoites were deterimentally affected with several ultrastructural changes as there was an extrusion of the conoid, which significantly changed the appearance of the apical region.
The acromioclavicular joint (AC) is a diarthrodial joint, stabilized by the coracoclavicular ligaments (conoid and trapezoid), the superior and inferior AC ligaments, and the AC capsule (Fig.
