SummaryAfter staining of the motor nerve endings with a cholinesterase technique and of nerve and muscle fibers with Sudanschwarz B, single muscle spindles were isolated from lumbrical muscles of rats and examined by means of light microscopy.Two types of intrafusal muscle fibres were found: a) pale ones corresponding to nuclear bag fibres and b) dark ones corresponding to nuclear chain fibres.On both types of muscle fibres distinct motor end plates were observed; two types of endplates can be…

SummaryIn a rat muscle spindle transversally cut into a series of alternating semithin and ultrathin sections, two different forms of nerve terminations were found on two neighbouring nuclear chain

Motor innervation of the cat muscle spindle studied by the cholinesterase technique

“Myofibrillar” adenosine triphosphatase staining reaction was used to identify nuclear bag1, nuclear bag2 and nuclear chain intrafusal muscle fibers, and histochemically deposits along the poles of the typical chain fibers in staining for cholinesterases were demonstrated.

The differentiation of intrafusal fibre types in rat muscle spindles after motor denervation

It can be concluded that intrafusal fibres do acquire their fibre type characteristics after fusimotor denervation despite complete deprivation of nerve impulse activity during the postnatal period when intraFusal fibre types differentiate in normal spindles.

Histochemical profiles of guinea-pig intrafusal fibres in normal muscles and after denervation, cordotomy and tenotomy

SynopsisHistochemical profiles of intrafusal fibres were analysed in normal muscles and in denervated, cordotomized and tenotomized preparations. Based on ATPase activity at polar regions, normal

The fine structure of de- and reinnervated muscle spindles

SummaryReinnervated muscle spindles in lower lumbrical muscles of rats studied 17 days to 24 months after crushing the sciatic nerve showed a series of alterations which have not been analysed, thus

The present paper records the results of a detailed study made on the innervation of muscle spindles in an Australian marsupial, Trichosurus vulpecula, using teased whole preparations and sectioned material to further the understanding of mammalian muscle spindle innervation as a whole.

Mammalian Intrafusal Muscle Fibres

The extent to which the muscle-fibre content of cat spindles represents the typical mammalian condition is determined, and the validity of this observation is ascertained.

Differences in the response of a muscle spindle primary ending to a standard stretch was observed during repetitive stimulation of single γ fibres, which were independent of the frequency of stimulation, the amplitude of stretch and the velocity of stretching.

A study of the morphology and innervation of muscle-spindles from the quadriceps of the rabbit and cat has shown that the intrafusal muscle-fibres do not subdivide in their course through the spindle, but retain their individuality from pole to pole.

THE LOCALIZATION OF CHOLINESTERASE ACTIVITY IN RAT CARDIAC MUSCLE BY ELECTRON MICROSCOPY

It is proposed that the localization of cholinesterases in myocardium at the ultrastructural level should be taken into account in considering the possible functions of these myocardial enzymes, and it is hoped that knowledge of their localization will open up new avenues of approach in considering their physiological role inMyocardium.
