SummaryThe fine structure of the tentacles of the articulate brachiopod Terebratalia transversa has been studied by light and electron microscopy. The epidermis consists of a simple epithelium that is ciliated in frontal and paired latero-frontal or latero-abfrontal longitudinal tracts. Bundles of unsheathed nerve fibers extend longitudinally between the bases of the frontal epidermal cells and appear to end on the connective tissue cylinder; no myoneural junctions were found. The acellular… 
Ultrastructure of the lophophoral coelomic lining in the brachiopod Hemithiris psittacea: functional and evolutionary significance
The ultrastructure of the lophophoral coelomic lining in the articulate brachiopod Hemithiris psittacea was studied using electron microscopy and confocal laser scanning microscopy. The coelomic
The periesophageal celom of the articulate brachiopod Hemithyris psittacea (Rhynchonelliformea, Brachiopoda)
TLDR
The microscopic anatomy and ultrastructure of the periesophageal celom is studied using scanning and transmission electron microscopy to facilitate ultrafiltration through the podocyte‐like cells.
An ultrastructural study of the opercular filament blood vessel ofPomatoceros lamarckii quatrefages (Polychaeta: Serpulidae)
TLDR
Observations suggest that these cells may be implicated in the synthesis and/or endocytosis of chlorocruorin molecules.

Development of the pedicle in the articulate brachiopod Terebratalia transversa (Brachiopoda, Terebratulida)
TLDR
The development of the pedicle in the articulate brachiopod Terebratalia transversa has been examined by electron microscopy and three regions are recognizable in the connective tissue compartment of the adult pedicle: a subepithelial layer of non-fibrous connectives, a central fibrous zone, and a proximal mass of tissue that resembles cartilage.
Fine structure of the coelomic epithelium of Sagitta elegans (Chaetognatha)
TLDR
The coelomic space in the trunk of the arrow worm Sagitta elegans is lined by a thin epithelium, which is composed of flat cells characterized by thin and thick myofilaments, which constitute the circular musculature of the gut.
Comparative larval myogenesis and adult myoanatomy of the rhynchonelliform (articulate) brachiopods Argyrotheca cordata, A. cistellula, and Terebratalia transversa
TLDR
The data indicate that larvae of rhynchonelliform brachiopods share a common muscular bodyplan and are thus derived from a common ancestral larval type.
Ultrastructure of the coelom in the brachiopod Lingula anatina
TLDR
The coelom of the lophophore in the brachiopod Lingula anatina was investigated using semithin sectioning, 3D reconstruction, and transmission electron microscopy and the ciliated myoepithelium can be considered as the ancestral type of coelomic lining.
Myoanatomy and serotonergic nervous system of plumatellid and fredericellid phylactolaemata (lophotrochozoa, ectoprocta)
TLDR
This study analysed the myoanatomy and serotonergic nervous system of adult representatives of the Phylactolaemata to show some support for the ‘Lophophorata’, but more comparative analyses of possibly related phyla are required.

TLDR
The analysis of the pattern of the peripharyngial nervous belt shows a precise organisation and the intrication of the connections which coordinate the tentacles and link the lophophore set to other pathways of general innervation.
Ultrastructure of sea urchin tube feet
TLDR
An analysis of the ultrastructure of the tube feet of three species of sea urchins revealed that the smooth muscle, although known to be cholinoceptive, receives no motor innervation.

TLDR
The tentacle of Rhabdopleura compacta (Hemichordata) consists of two layers of cells surrounding a central coelomic cavity and the muscle cells to the layer of cells within the basement lamella.

The architecture and function of the lophophore of the marine bryozoan Cryptosula pallasiana (Moll) are described, including some new features not previously discovered in bryozoans. The nature of
Structure and function of an entoproct tentacle with a discussion of ciliary feeding types
TLDR
Electron microscopical studies of Loxosomella elegans show that a cross section of a tentacle typically shows one large frontal cell with short cilia and in some cases small mucus vesicles, among which nerves in contact with the lateral cells have been identified.
THE ULTRASTRUCTURE OF THE CAT MYOCARDIUM: I. Ventricular Papillary Muscle
TLDR
In papillary muscles worked in vitro without added substrate, there is a marked depletion of both glycogen and lipid, and no morphological evidence for preferential use of glycogen was found.

TLDR
Both in development and in the form and function of the organ in the adult, the lophophore of C. anomala closely resembles that of the articulate species Tegulorhynchia nigricans (Sowerby): it is suggested that this reflects an inherent limitation on the possible variety of lophphores in brachiopods.
Aspects of the Functional Morphology of the Lophophore in Articulate Brachiopods
TLDR
Histologic studies made on three species of articulate brachiopods provide information on the structural integrity, epithelial specialization and other cellular aspects of the lophophore, and similarities in staining properties of granular inclusions found in the matrix suggest movement between cells within the matrix and the epithelium.
COORDINATED DEVELOPMENT OF THE SARCOPLASMIC RETICULUM AND T SYSTEM DURING POSTNATAL DIFFERENTIATION OF RAT SKELETAL MUSCLE
TLDR
An electron microscope study has been carried out on rat psoas muscle, during the early postnatal stages of development, and the sarcotubular system undergoes the most striking modifications during this period.
