Muscle-Spindle Histochemistry

Science, 1967
Reduced nicotinamide adenine dinucleotide tatrazolium reductase is abundant in cat intrafusal muscle fibers, whereas in the toad its activity is equal to that in extrafusal fibers. Spindles of both species contain little fat. In sections stained for adenosine triphosphatase bound to myofibrils, two types of intrafusal muscle fibers appear in spindles ...

The Mechanical Spindle: A Replica of the Mammalian Muscle Spindle

Proceedings of the 15th Annual International Conference of the IEEE Engineering in Medicine and Biology Societ, 1995
The goal of the recently initiated Anthroform Arm Project is to understand the manipulation capabilities of the human arm through the development of a dynamically accurate replica arm. Previous attempts have focussed on manipulator kinematics, and have neglected dynamics and controller designs.

Morphology of muscle spindles in the rat

Experientia, 1968
Die Morphologie und Innervation der Muskelspindeln der Lumbricalmuskulatur im Hinterfuss der Ratte wird beschrieben. Eine typische Muskelspindel enthalt zwei «nuclear bag» Fasern und zwei «nuclear chain» Fasern. Jede Spindel enhalt 2 motorische Nerven, einer innerviert die «nuclear bag» Fasern, der andere die «nuclear chain» Fasern.

Capsules of duck muscle spindles

Cell and Tissue Research, 1980
Duck muscle spindles show a large outer capsule enclosing a number of intrafusal muscle fibres which are individually encircled by an inner capsule. The outer capsule consists of a multilayer of 4-6 flattened cells with elongated nuclei, and are usually lined by a basement membrane. They resemble and are linked with perineural cells of the nerve bundle

Responses of muscle spindles in a tortoise

Brain Research, 1975
Responses were recorded from muscle spindles in the extensor digitorum longus muscle of the freshwater tortoise Chelodina longicollis. Most spindles showed no resting discharge unless the muscle was stretched up to a millimetre beyond the minimum body length. The firing rate then increased by 2-5 imp./sec/mm extension.

Muscle Spindles and the Regulation of Movement

Physical Therapy, 1980
This paper presents the complexities of muscle spindle structure and function. Experimental evidence indicates that the contribution of muscle spindles to motor control depends upon the cooperation of two distinct systems, one dynamic and one static. The traditional idea that load compensation depends on the segmental stretch reflex action of muscle ...

Structural Model of the Muscle Spindle

Annals of Biomedical Engineering, 2002
A model of the muscle spindle was developed based on its anatomical structure. The model contains three intrafusal fibers (bag1, bag2, and chain), two efferents (dynamic gamma efferent to the bag1 fiber and static gamma efferent to bag2 and chain fibers), and two afferents [primary (Ia) and secondary (II)].

Muscle spindles in the rat diaphragm

Experientia, 1965
Elektrophysiologische Registrierungen afferenter Impulse des Nervus phrenicus aus dem isolierten Rattenzerchfell wurden durch eine histologische Untersuchung des Zwerchfelles unterbaut. Das Vorkommen von durchschnittlich 3 Muskelspindeln in jeder Zwerchfellhalfte wurde nachgewiesen.

Human Muscle Spindle Histochemistry

Archives of Neurology, 1969
SEVERAL recent histochemical studies of muscle spindles 1-9 have demonstrated the relative activity of various enzymes and other components in the different types of intrafusal fibers. With a single exception consisting of a brief report 6 these results were based on studies of subhuman species.

Microvasculature of Rabbit Muscle Spindles

Archives of Neurology, 1979
The microvasculature of the muscle spindle and its relationship to the microcirculation of teniussimus extrafusal muscle is described. Muscle spindles lie in close proximity and parallel to the central artery, vein, and nerve. The arterioles to spindle capillaries are third to fourth order branches of the central artery, whereas most arterioles to ...
