Muscle fibre type populations of human leg muscles
The Histochemical Journal, 1975Four selected leg muscles (gastrocnemius, soleus, vastus lateralis and intermedius) from thirty-two humans were autopsied within 25 hr of death and examined histochemically. The results of histochemical myofibrillar adenosine triphosphatase activity demonstrated that the soleus and vastus intermedius muscles have a higher proportion of slow twitch ...

Simulation of the spatial distribution of muscle fibres in human muscles
Computer Methods and Programs in Biomedicine, 1986A composite muscle cross section model was simulated on a VAX 780 computer. The various motor unit territories in the cross section area were circular, partially overlapping each other. The radii of the territories of the motor units, their centres, and the number of muscle fibres in each motor unit were treated as random variables.

Muscle-fibre architecture of the rat medial pterygoid muscle
Archives of Oral Biology, 1987The detailed fibre architecture of the rat medial pterygoid muscle, including the courses and attachment points of muscle fibres, was investigated histologically in 10 micron thick serial sections in the horizontal, coronal and parasagittal planes.

Muscle Fibre Types in Mammalian Muscles
1985Human muscle tissue appears macroscopically more or less alike, but in small mammals the muscles often differ in colour. Ranvier (1873) observed that red muscles of rabbits contracted slowly and that they consisted of fibres with much sarcoplasm and distinct longitudinal striations; the white muscles were fast and the histological picture of the fibres

Abstract Many natural and synthetic materials (e.g. plastics, wood, textiles, bone, nucleic acids, proteins, polysaccharides) are made of polymer molecules. Polymers comprise repeating subunits joined together end-to-end like beads on a string to form very long molecules. In some cases (e.g.

The discussion how mammalian muscle fibres could be subdivided into fibre types was provoked not only by observations on red and white mammalian muscles (see Chap. D) but also by the fact that amphibia have some muscles with outstanding functional properties. These muscles contract slowly, and respond with lasting contractions to acetylcholine and not,

More than 80% of the volume of an adult muscle fibre is occupied by myofilaments. There are two types: (a) thick myosin filaments, 1.6 μm long and 12–14 nm in diameter, and (b) thin actin filaments, 0.98 μm long and 5–7 μm in diameter (frog, Page and Huxley 1963).

Junctions between Muscle Fibres in Cat Extraocular Muscles
Nature, 1970MOST mammalian striated muscles possess a discretr-innervation band with the motor nerve terminals lying midway between the origin and insertion of the muscle fibres. The extraocular muscles of the cat, however, do not have a discrete innervation band, and motor endplates may be found anywhere within the middle two-thirds of the muscle.

Muscle fibre type adaptation in the elderly human muscle
Scandinavian Journal of Medicine & Science in Sports, 2003This short review discusses changes in the fibre type distribution, myosin heavy chain isoform composition and histological appearance of the very elderly human skeletal muscle. Point of origin of the discussion comes from data that we have obtained from muscle biopsies from the vastus lateralis muscle of a group of frail very elderly subjects (age ...
