    Notes: Summary Three types of subsurface cisterns were observed in Purkinje cells of the cerebellum of the Syrian hamster. The type-1 cisterns are subsynaptic, related to axosomatic synapses, and are separated from the postsynaptic cell membranes with distances of 400–800 Å. These are probably modified rough surfaced endoplasmic reticulum. The type-2 cisterns are closely apposed to the surface membranes of Purkinje cells, and have very little intracisternal space except at the dilated lateral edges. The type-3 cisterns are similar in structure to the type-2 cisterns but in addition are closely associated with mitochondria. The type-2 and type-3 cisterns appear between one and two weeks after birth and are still present in adults, having almost the same frequency of occurrence. Thin cell processes opposite the type-2 and type-3 cisterns are considered to be glial cell processes. The morphological details of these types of subsurface cisterns are described here, and their possible functional significance is briefly discussed.

    Some observations on the fine structure of nerve cell bodies and their satellite cells in the ciliary ganglion of the chick (1965)

    Notes: Summary The fine structures of the ciliary ganglion cell and its satellite cell of the chick were studied by means of electron microscope. The general appearance of the ganglion cell soma is similar to those of other ganglion cells. In this paper, particular attentions were paid to the number- and area estimations of the nuclear pores, peculiar intracytoplasmic filamentous structures and “coated” vesicles in the Golgi area. In addition, centrioles with cross-striated rootlets were observed in the perikaryon of the nerve cell. Brief discussions were made on these intracytoplasmic organelles.

    Some observations on the fine structure of the synaptic area in the ciliary ganglion of the chick (1965)

    Notes: Summary The fine structure of the synaptic area in the ciliary ganglion from 10-days chick embryo to the adult was studied by electron microscopy. The ciliary ganglion cell is unipolar and a considerable surface of which is covered by the calyx terminal. The peripheral part of the calyx divides into several terminal knobs and form a basket terminal. Four types of contact configurations were observed in the calyciform ending: 1) contact area without membrane specialization which occupies the most part of the contact, 2) desmo-some-like structure which is observed in various places of the contact surface, 3) synaptic complex and 4) close apposition of apposing plasma membranes. The presence of the synaptic complex and the close appositon of apposed plasma membranes seems to correspond to the dual natures of the transmission obtained by Martin and Pilar (1963a, b). In addition, some considerations were made on the subsurface cistern and on the possible functional significance of the myelin sheath surrounding the ganglion cell and the calyx.

    Special somatic spine synapses in the ciliary ganglion of the chick (1967)

    Notes: Summary “Somatic spine synapses” modified with postsynaptic electron opaque materials were found in the axo-somatic ciliary ganglion synapse of the chick. A part of the postsynaptic cell body protrudes into the presynaptic calyciform ending as a somatic spine with about 1 μ in length and 0.15 μ in diameter, and forms the so-called synaptic complex with presynaptic process. Moreover, conspicuous electron opaque materials can be seen in the central axis of the spine, except for its end portion. Sometimes, these opaque materials are seen as arrayed dots. The morphological characteristics of the somatic spine synapses in this study are quite similar to that found in the habenula and interpeduncular nuclei of the cat (Milhaud and Pappas, 1966). the biological significance of which is obscure at present.

    A description of the times of appearance and regression of marginal lingual papillae in human fetuses and newborns (1982)

    Notes: Papillae, located along the anterolateral margin of the human tongue, were observed in fetal and newborn stages. The papillae appeared in the prenatal period and attained maximum development in the newborn. They had almost disappeared by the time of weaning. Although morphologically, the papillae may be considered to be a form of the filiform papillae, they differed from the filiform papillae in that they were temporary, localized at the anterolateral margin of the tongue, and larger in size. These papillae are homologous with those in certain land mammals and toothed whales, and may assist in sucking. Our findings on the times of appearance and regression of marginal papillae support this notion.
