The pharyngeal jaw apparatus of labrid fishes: A functional morphological perspective

Journal of Morphology, 1986
AbstractAmong the acanthopterygian fishes, the Labridae possess the most highly integrated and specialized pharyngeal jaw apparatus. The integrated feature involves many osteological components and aspects of muscle form, architecture, composition, and function. The upper jaw articulates by means of a true diarthrosis with the pharyngeal process of the

On Relative Growth in the Jaws of Certain Fishes.

Proceedings of the Zoological Society of London, 1935
Summary. 1 In Lepidosteus osseus growth of the jaws relative to the rest of the body is of the type termed heterogonic. 2 There are two quite distinct periods in this growth, both showing heterogony, the growth coefficient being much higher over the first than over the second period. 3 The growth of the jaws relative to the rest of the body

Anatomical and Physiological Peculiarities of the Heart in Jawless and Jawed Fish

Journal of Evolutionary Biochemistry and Physiology, 2021
The heart of jawless fish (Cyclostomata; lamprey, hagfish) and jawed fish (Teleostei) is homologous to the heart of higher vertebrates. A study of this organ in archaic Cyclostomata and Teleostei, which are different in their evolutionary “ages”, genetic characteristics and hypoxia tolerance, is of particular interest in the search for the factors that

[Jaws of fish 1].

Clinical calcium, 2005
A group of fish is not a mophyletic and includes some different classification groups. Fish are the popular name of animals which has the shape of fish. Most of fish bear jaw, but some fish do not have jaws. Formation of jaw is an important event in the history of early vertebrates. Jaws are originated from visceral arches.

Jaws: The Inside Story. The Metabolism of Elasmobranch Fishes

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1997
Abstract Elasmobranchs are of metabolic interest for several reasons, including their primitive evolutionary position, their osmotic strategy and their low incidence of neoplasia. Some aspects of the metabolism of elasmobranch fishes are unique when compared with those of the other vertebrates.

[Jaws of fish 2].

Clinical calcium, 2005
Structure of Jaws in fish composed of mandibular and hyoid arches. Hyomandibular which is upper part of hyoid arch plays an important role of jaw suspension. Various jaw structures are developed in fish. One of the samples is protrusible upper jaw in cyprinid fish.

Evolution of the upper jaw mechanism in teleost fishes

Journal of Morphology, 1935
AbstractThis study reveals the existence of four distinct but genetically related types of upper jaw mechanisms:1. The non‐protractile, with no mechanism for the protrusion of the pre‐maxillae. The maxillaries form part of the upper margin of the mouth, as in Isospondyli, Apodes and Haplomi.2.

Sclerotic plates or circumorbital bones in early jawed fishes?

Palaeontology, 2010
Abstract:  Circumorbital dermal bones are found in most groups of early vertebrates that have dermal bony plates on the head. Taxonomic distribution of dermal sclerotic plates on the eye itself is less clear, partly because the eyeball is rarely preserved and sometimes because sclerotic bones have been misinterpreted as circumorbital bones.

Acanthodian fishes with dentigerous jaw bones: the Ischnacanthiformes and Acanthodopsis

2004
Within the early gnathostome group Acanthodii, several different types of dentition are exhibited. Of the Siluro-Devonian acanthodians, some of the Climatiidae and the Brochoadmonidae have rows of small tooth whorls lining their jaws, while the Ischnacanthidae and Poracanthodidae have dermally derived dentigerous jaw bones, with some taxa also having a
