SummaryUltrastructural examination of the podium of the asteroid echinoderm Stylasterias forreri has revealed that cells of the coelomic epithelium and cells of the retractor muscle should be considered as components of a single epithelium. The podial retractor cells are, therefore, myoepithelial in nature. This report concentrates on those ultrastructural features of the retractor cells that are most likely involved with excitation-contraction coupling. The spatial arrangement of the…

Ultrastructure of the coelomic lining in the podium of the starfish Stylasterias forreri
TLDR
It is concluded that the coelomic lining in the podium of S. forreri is a bipartite epithelium and that the retractor cells of the podium are myoepithelial in nature.
Scanning electron microscopy of echinoid podia
TLDR
The results agree with previous conclusions concerning tube-foot structure based on transmission electron microscopy, and provide additional information, particularly with regard to the outer and inner epithelia.
Organization of the coelomic lining and a juxtaposed nerve plexus in the suckered tube feet of Parastichopus californicus (Echinodermata: Holothuroida)
The coelomic lining of the water‐vascular canal in a suckered tube foot from the sea cucumber, Parastichopus californicus, is a pseudostratified myoepithelium consisting of flagellated adluminal
Neuroanatomy of the tube feet and tentacles in Holothuria glaberrima (Holothuroidea, Echinodermata)
TLDR
The direct innervation of the podia by the ectoneural component of the nervous system, as well as the existence of a connection between the nervousSystem components in the main nerves, the muscle, and the connective tissue, are shown.
Larval myogenesis in Echinodermata: conserved features and morphological diversity between class‐specific larval forms of Echinoidae, Asteroidea, and Holothuroidea
TLDR
All tested species of Echinodermata exhibited both conserved features of muscle morphology during development indicating a common life history strategy and a planktonic habitat, and also an extensive morphological diversity representing specific anatomical adaptations during development.
Functional anatomy of the valves in the ambulacral system of sea urchins (Echinodermata, Echinoida)
TLDR
The hypothesis of multiple control of the ampulla-tube foot system is lead to by the lateral and podial nerves which release transmitter substances that diffuse through the connective tissue up to the muscle layers.
Evolution of Excitation-Contraction Coupling.
TLDR
The genomes of animals and their close relatives are surveyed, to explore the evolutionary history of genes encoding three proteins pivotal for ECC: L-type VGCCs; RyRs; and a protein family that anchors intracellular organelles to plasma membranes, namely junctophilins (JPHs).

Ultrastructure of cephalopod chromatophore organs
TLDR
The surface of a retracted chromatophore is extensively folded, but upon contraction of the radial muscle fibers it becomes flattened and the folds of the surface disappear, indicating that the cell membrane cannot be responsible for the elasticity of the chrom atophore as claimed by earlier investigators.
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
Suckers of principal tube feet of a regular echinoid,Diadema antillarum, are described in an electron microscopic study and a granule-filled secretory cell-type is described that possesses long tracts down which the granules pass to terminate on the contact edge of the sucker in secretion packets.

SummaryAn ultrastructural study of the tube foot wall of a regular echinoid,Diadema antillarum, was made. Ciliated microvillous epithelial cells, their inclusions, amoebocytes, and the arrangement of
The basiepithelial nerve plexus of the viscera and coelom of eleutherozoan echinodermata
TLDR
The distribution of the basiepithelial plexus in various tissues described by other workers is dicscussed particularly in relation to whether it is the coelomic epithelium or the luminal epithelia which is innervated.
The innervation of the ampulla of the tube foot in the starfish Astropecten irregularis

TLDR
The fibres which run along the seam of the ampullae, formerly described as axons, are extensions of muscle cells, to which they can be traced and it is proposed that some stain selectively and give rise to the structures originally described as ribbon axons.
On the Occurrence and Structure of Choanocyte-like Cells in Some Echinoderms
TLDR
The present report together with previously published data lend support to the idea, that the choanocyte is a fundamental cell type in metazoans, probably derived phylogenetically from some flagellate ancestor.
Ultrastructure of the basiepithelial nerve plexus of the sea urchin, Centrostephanus longispinus
TLDR
The basiepithelial nerve plexus of the Echinoid, Centrostephanus longispinus, contains strands of nerve fibres, which measure between 0.1 and 2.0 μm in diameter, and by means of serial sectioning the structure of multipolar cell bodies within the plexi could be demonstrated.
