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)].

Classification of muscle spindle receptors

Brain Research, 1986
The conduction velocities of muscle spindle afferent fibers have a bimodal distribution, and classifications of spindle receptors based on afferent fiber diameter have therefore divided these receptors into two groups, the well known primary and secondary endings.

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 ...

Responses of Muscle Spindles in the Lizard

Nature, 1967
IN the past 30 years many experiments have been carried out on the structure and function of muscle spindles in both amphibia and mammals. There have been no accounts of experiments concerned with the function of muscle spindles in reptiles although their structure has been described1,2.

The distribution and abundance of muscle spindles

Brain Research Bulletin, 2008
This commentary suggests that the distribution and abundance of muscle spindles in different muscles is related to their role as signallers of muscle fascicle length. Large muscles comprising many fascicles will therefore have more spindles than smaller muscles.
