SummaryThe blood-water pathway in respiratory lamellae of teleostean gills consists of an epithelial layer one or two cells thick, a basal lamina and a thin layer of cytoplasm which lines the blood lacunae. This layer of cytoplasm is formed by flange-like extensions of the pillar cells. The resulting location of the pillar cell perikarya between the surfaces of the blood lacunae is probably of paramount importance for maintenance of the flattened form of the lamellae.Collagenous bundles… 

The fine structure and innervation of gill lamellae in Anodonta

The Anodonta trabecular cell is not analogous with the pillar cell of fish gills but rather with muscle cells which show a specific morphological modification and a peculiar relationship to the vessel wall due to the absence of the endothelium.

The structure of the gill of the trout, Salmo gairdneri (Richardson)

A mechanism for the control of blood flow to suit the respiratory requirements of the fish is suggested, which involves a system of recruitment of additional respiratory units and changes in overall blood flow patterns.

Development of secondary lamellae of the gills of the trout, Salmo gairdneri (Richardson)

A light and electron microscope study of secondary lamellae of trout developing at 10° C is described, finding that chloride cells are present in much greater numbers in developing gills than in the adult.

SummaryThe anatomy of the blood supply to the gills of the dogfish, Scyliorhinus canicula, is described. The anatomical basis for a counter-current exchange system at the respiratory surfaces is

Fine structure of the respiratory organs of the Climbing perch, Anabas testudineus (Pisces: Anabantidae)

The hypothesis that the air-breathing organs represent modified gills is not supported by this study, and evidence concerning the possible homology of pillar cells with plain muscle cells is discussed.

Ultrastructural study of arterio-venous anastomoses in gill filaments of Tilapia mossambica

Arterio-venous anastomoses (AVA) in gill filaments of Tilapia mossambica exhibit a distinct polarity and possible functions of the AVAs, including osmoreception are discussed.

The secondary lamellae of the gills of cold water (high latitude) teleosts

Low environmental water temperatures may be related to the distribution of mucous cells and chloride cells on the secondary lamella of the teleost gill of the winter flounder and the antarctic cod, Trematomus borchgrevinki.

A light and electron microscope study of the gills of larval lampreys (Geotria australis) with particular reference to the water‐blood pathway.

The gills of ammocoetes of the Southern Hemisphere lamprey Geotria australis have been studied using light and electron microscopy. Emphasis has been placed on describing the structures and vessels

Mitochondria-rich (chloride) cells in the gill epithelia from four species of stenohaline fresh water teleosts

Results suggest that chloride cells may be a rather common occurrence in the gill epithelia of stenohaline fresh water teleosts, and may function in ion-transport in these fishes in fresh water environments.

New aspects of the intrafilamental vascular system in gills of a euryhaline teleost, Tilapia mossambica

According to these results, non-respiratory intrafilamental blood shunting appears unlikely and AVAeff are assumed to be the main route for blood entering the central venous sinus which would consequently flow into the branchial veins.

FINE STRUCTURE AND MORPHOGENIC MOVEMENTS IN THE GASTRULA OF THE TREEFROG, HYLA REGILLA

The blastoporal groove of the early gastrula of the treefrog, Hyla regilla, was examined with the electron microscope and a theory of invagination is proposed, based on contraction and expansion of the dense layer and the tight junctions at distal cell surfaces.

A comparative study of the branchial epithelium in fishes, with special reference to extrarenal excretion

There is no indication of any specialization in the branchial epithelium of fishes indicating a special role in extrarenal excretion and mucous cells are the only specialized secretory cells which occur in the gills.

It is concluded that more active fish not only have larger gill areas but that the conditions for gaseous exchange are better than for more sluggish forms and that the area is increased in such a way as to keep the resistance to flow to a low value.

Morphological classifications of vertebrate blood capillaries.

Morphological features of blood capillaries from various vertebrate forms and organs are presented and it is suggested that these varying capillary structural features may be relevant to problems relating to exchange of materials between blood plasma and parenchymal cells.
