    Notes: Summary The subepithelial blood vessels of the dorsal surface of the tongue in young kittens has been studied by scanning electron microscopy of microcorrosion casts. These vessels entwine the vallate papillae distributed in the pharyngeal part of the tongue, form hairpin loops in association with the small conical papillae along the sides and at the tip of the tongue and establish regularly distributed subpapillary conglomerations over almost its entire oral part. These conglomerations lie directly on veins. Small arterioles reach the vessels surrounding the individual subpapillary conglomerations. By contrast with the arrangement of the superficial vascular bed in the tongue of the dog and some other mammals, no anastomoses between arteries and veins were observed in the kitten between the vessels which supply and drain the subepidermal capillaries.

    Fine structure of pars neuro-intermedia of the loach, Misgurnus fossilis L. (1970)

    Notes: Summary Two types of glandular cells are present in the pars intermedia of the loach, Misgurnus fossilis. Basophils are characterized by the presence in their cytoplasm of numerous secretory granules containing electron-dense and homogeneous material and by scarce endoplasmic reticulum. ‘Weak’ acidophils contain in their cytoplasm abundant endoplasmic reticulum and numerous granules of different electron densities. The distal part of the neurohypophysis is composed of several types of neurosecretory axons, strongly branched pituicytes, numerous capillaries, and connective tissue elements. The axon terminals form the neuroglandular, neurovascular and neurointerstitial contacts. Some axon terminals are closely apposed to the basement membrane separating neurohypophysis from meta-adenohypophysis. At points of absence of continuity of this membrane, some neurosecretory axons become directly contiguous with cytoplasmic membranes of the intermedia cells.

    Scanning electron microscopy of microcorrosion casts of the vascular bed in the skin of the spotted salamander, Salamandra salamandra L. (1979)

    Notes: Summary Microcorrosion casts of blood vessels in the skin of the spotted salamander, Salamandra salamandra L., were studied using scanning electron microscopy. The investigated vessels include a subepidermal network of respiratory capillaries and the vessels of poison glands. A hypothesis is proposed, according to which both types of vascular beds possess a common origin. Probable factors involved in the differentiation of the primary netword of the subepidermal vessels in larvae are indicated and speculation concerning the supposed mosaic type of circulation in the capillaries of the subepidermal respiratory bed is presented.

    Model of skin vascularization in Rana esculenta L.: Scanning electron microscopy of microcorrosion casts (1978)

    Notes: Summary Microcorrosion casts of blood vessels in the skin of Rana esculenta L. were examined by means of scanning electron microscopy with particular reference to the subepidermal network of respiratory capillaries. Due to the fact that arteries and veins lie in the deeper layers of the stratum spongiosum of the corium, the respiratory vessels form a morphologically homogeneous network. Functionally, however, this network is subdivided into small areas with a centripetal direction of blood flow. The deep capillary net, situated at the base of the stratum compactum of the corium, is not so dense as the respiratory network and does not directly communicate with it. Alveolar glands of the skin have no effect on the distribution of capillaries in the two networks.
