SummaryThe innervation of the connective tissue ligaments between the oral plates on the arm of a brittlestar by small branches of the hyponeural motor system is described. These branches arise from the hyponeural part of each segmental ganglion and pass laterally round the nerve cord and then orally across the epineural sinus to penetrate a small intersegmental node of juxtaligamental tissue located centrally. The endings of the nerve branches contain numerous small agranular vesicles and make… 
The tendons of Ophiocomina nigra and their role in autotomy (Echinodermata, Ophiuroida)
TLDR
The results of a simple experiment implicate the juxtaligamental cells in the control of tendon extensibility and a possible mechanism for this control is presented.
A physiological study of the correlation between motor output in hyponeural nerves and arm movements in the brittlestar Ophiura ophiura
TLDR
This study shows that the largest size of giant interneurones in the ectoneural nerve cord are not command fibres and, in general, do not directly drive motor output.
The compass depressors ofParacentrotus lividus (Echinodermata, Echinoida): ultrastructural and mechanical aspects of their variable tensility and contractility
TLDR
Stress-strain tests show that treatment with 1 mM acetylcholine or 100 mM K+ ions can increase reversibly the stiffness of the compass depressor to an extent that cannot be due to contraction of the myoepithelium, suggesting that the mechanical properties of the ligament are under physiological control.
Is muscle involved in the mechanical adaptability of echinoderm mutable collagenous tissue?

TLDR
It is concluded that there is no evidence that the variability of the passive mechanical properties of any mutable collagenous structure is due to muscle.
Mechanical Properties of the Compass Depressors of the Sea-Urchin Paracentrotus lividus (Echinodermata, Echinoidea) and the Effects of Enzymes, Neurotransmitters and Synthetic Tensilin-Like Protein
TLDR
It appears that neither hyaluronic acid nor sulphated glycosaminoglycans have an interfibrillar load transfer function in the CD, indicating that, in contrast to holothurian tensilins, the echinoid molecule may not be involved in the regulation of collagenous tissue tensility.

TLDR
It is argued that MCT could be a source of, or inspiration for, new pharmacological agents and strategies designed to manipulate therapeutically connective tissue mechanical properties and new composite materials with biomedical applications.

The giant neurone system in ophiuroids
TLDR
Degeneration studies confirmed the layout of the hyponeural motor axons and the juxtaligamental tissue is thought to be associated with changes in the structural properties of the collagenous ligaments of the arm during arm autotomy.

TLDR
It is suggested that the juxtaligamental cells may be involved in the rapid loss of tensile strength which the intervertebral ligament sustains during arm autotomy by controlling the availability of Ca2+ ions to the extracellular compartment of the ligament.
Nervously mediated change in the mechanical properties of a brittlestar ligament
TLDR
It is concluded that the response to potassium ions in the intervertebral ligament of Ophicomina nigra occurs by nervous mediation, and supports the view that brittlestar arm autotomy involves a nervously mediated change in the mechanical properties of the intersegmental connective tissues.
THE NEUROBIOLOGY OF THE ECTONEURAL/HYPONEURAL SYNAPTIC CONNECTION IN AN ECHINODERM
TLDR
The report describes in detail, using simultaneous recording from two electrodes, how activity within the ectoneural system drives the hyponeural motor system and thus produces muscular contractions in the intervertebral muscles.
Variable tensility in echinoderm collagenous tissues: A review
TLDR
Mechanical and ultrastructural data suggest that the compliant state of parallel‐fibred MCTs is achieved through the destabilization of interfibrillar linkages which permits slippage between adjacent collagen fibrils.

TLDR
The present results suggest that the cohesive force between the collagen fibrils rather than the contractile activity of the muscle cells plays a significant role in determining the mechanical properties of the CA.
Factors Regulating the Mechanical Properties of Holothurian Dermis
TLDR
chemical stimulation of the dermis with coelomic fluid of the sea cucumber, or with artificial sea water containing a high concentration of potassium, increased both the elastic stiffness and the viscosity and affected the mechanical properties of other echinoderm connective tissue in a similar way to the holothurian dermis.

TLDR
It is suggested that linkages sensitive to low pH and those mediated by Ca2+ play a significant role in determining the mechanical properties of the CA.
