Intracranial portion of the trochlear nerve and dorsal oblique muscle composition in dog: a structural and ultrastructural study.

abstract：:To date, the phylum Cycliophora comprises only one described extant species of acoelomate marine invertebrates, Symbion pandora. Adult specimens live commensally on the mouthparts of the Norwegian lobster, Nephrops norvegicus. Its complicated life cycle includes an asexually produced Pandora larva and a sexually produ...
