Components
The primitive arrangement is 7 (possibly 8) arches, each consisting of the same series of paired (left and right) elements, in order of dorsal to ventral: Pharyngobranchial, epibranchial, ceratobranchial, hypobranchial, and basibranchial. The pharyngobranchials articulate with the neurocranium, while the left and right basibranchials connect to each other (often fusing into a single bone). When part of the hyoid system, the names of the bones are altered by replacing "branchial" with "hyal", thus "ceratobranchial" becomes "ceratohyal".

Famous quotes containing the word components:
“Hence, a generative grammar must be a system of rules that can iterate to generate an indefinitely large number of structures. This system of rules can be analyzed into the three major components of a generative grammar: the syntactic, phonological, and semantic components.”
—Noam Chomsky (b. 1928)
