A histological study of post mortem changes in the skeletal muscle of the fowl (Gallus domesticus). I. The muscle fibres. 1978

A F MacNaughtan

The changes in the histology of skeletal muscle post mortem have been studied with the light and electron microscopes in the pectoralis thoracica and iliotibialis muscles of the fowl (Gallus domesticus). The carcasses were stored at 40 degrees C and samples removed at various times post mortem. Kinking, contractures, transverse splitting and disintegration were seen in muscle fibres from post mortem muscle. The variation in time and frequency of occurrence of these was wide but no consistent difference between the pectoralis and iliotibialis muscles was found. An attempt was made to integrate the results from the light and electron microscopes to gain insight into the nature of the modifications occurring in the histology of post mortem muscle fibres.

UI	MeSH Term	Description	Entries
D008854	Microscopy, Electron	Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.	Electron Microscopy
D009119	Muscle Contraction	A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement.
