Subsequent elimination of the interclavicle in the Anuran line of descent, and decrease of ossification, left a girdle like that of Protobatrachus, Notobatrachus, Ascaphus and Leiopelma.
In Crocodiles it is a cartilage to which the sternal ribs unite; and upon its front portion a flat knife-like bone called the interclavicle is placed.
The interclavicle is absent from all mammals except Echidna and Ornithorhynchus.
Von Meyer noticed the resemblance of this anterior process to the interclavicle of the Crocodile in position; but it is more like the keel of a bird's sternum, and is not a separate bone as in Reptiles.
There are probably no precoracoids, but clavicles and a T-shaped interclavicle are well developed.
In the shoulder-girdle the coracoids are large and meet in a ventral symphysis; precoracoids and a sternum are apparently absent, but parts generally regarded[71] as the clavicles and interclavicle are well developed.
According to Hulke they should be regarded as the omosternum,--the clavicles and interclavicle being wanting.
A pectoral girdle and sternum, with clavicles and a T-shaped interclavicle are developed, and abdominal ribs are always found.
There is no separate interclavicle and hardly any trace of a precoracoid.
A precoracoid (epicoracoid) occurs in front of the coracoid, and there is a large interclavicle (fig.
They probably represent the interclavicleand clavicles.
In the Sauropterygia bones regarded as the clavicles and interclavicle are generally well developed.
Traces of an interclavicle may occur in the embryo.
There is never any interclavicle in the adult, though sometimes traces of it occur during development.
The three anterior elements of the plastron are respectively homologous with the interclavicle and two clavicles of other reptiles, while the remaining elements of the plastron are probably homologous with the abdominal ribs of Crocodiles.
Clavicles and a T-shaped interclavicle are commonly present, but are absent in the Chamaeleons.
The clavicles rest on a large discoidal, rhomboidal, or T-shaped median bone, which clearly corresponds to the interclavicle of reptiles.
No interclavicleis present in Urodela, but in this group and in a number of the Anura, a process grows out from the end of each of the bars (praecoracoids) which Goette holds to be the clavicles.
Parker gives a very different account of the interclaviclein Anguis.
Gegenbaur admits the lateral elements as parts of the interclavicle, while Parker holds that they are not parts of an interclavicle but are homologous with the omosternum of the Frog, which is however held by Goette to be a true interclavicle.
With reference to the clavicle and interclavicle Parker (No.
The interclavicle (episternum) is held by Goette to be developed from a paired formation at the free ventral ends of the clavicles, but he holds views which are in many respects original as to its homologies in Mammalia and Amphibia.
There are short lateral processes at the point where the interclavicle was overlapped by the clavicles, but we cannot be sure of the extent of this bone anteriorly or posteriorly.
The posterior end of the interclavicle lies in contact with the right scapulocoracoid.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "interclavicle" in a variety of sentences. We hope that you will now be able to make sentences using this word.
