TLDR
It is suggested that in the first branchial arch muscles this is probably not directly comparable to the situation in the typical limb muscle, and therefore their common origin with the jaw-closers cannot be responsible for the occurrence of IIM fibres in tensor veli palatini and tensor tympani in some species.Abstract:
A combination of standard histochemical techniques and immunohistochemical staining using myosin type-specific antisera was used to determine the fibre-type composition of the muscles of first branchial arch origin (that is, masseter, temporalis, pterygoideus medialis and lateralis, tensor veli palatini, tensor tympani, anterior digastricus and mylohyoideus) in a wide range of the Carnivora and the Primates.read more

Fiber types in mammalian skeletal muscles.
TL;DR: Mammalian skeletal muscle comprises different fiber types, whose identity is first established during embryonic development by intrinsic myogenic control mechanisms and is later modulated by neural and hormonal factors.

Myosin heavy chain isoform expression following reduced neuromuscular activity: potential regulatory mechanisms.
TL;DR: The data suggest that the regulation of MHC isoform expression involves a complex interaction of multiple control mechanisms including the myogenin:MyoD and calcineurin:NF‐AT pathways; however, other intracellular signaling pathways are likely to contribute.

Muscle-spindle distribution in relation to the fibre-type composition of masseter in mammals.
TL;DR: Common to all species, but strongest of all in the rat, was a close association between the distributions of muscle spindles and extrafusal Type I (slow twitch) fibres within the masseter complex.

Comparative study of myosins present in the lateral muscle of some fish: species variations in myosin isoforms and their distribution in red, pink and white muscle.
TL;DR: The ATPase activity of myosin isoforms was examined histochemically using methods to demonstrate their acid- and alkali-lability and their Ca-Mg dependent actomyosin ATPase.
Book ChapterDOI
Skeletal Muscle Function
TL;DR: This chapter attempts to outline the great diversity that exists in skeletal muscles and hopes that the knowledge and techniques developed over the past three decades will find their rightful introduction and application to increase recognition and understanding of neuromuscular disorders in clinical veterinary medicine.

Functional significance of cell size in spinal motoneurons
TL;DR: The present paper is concerned with the central part of the motoneuron and the significance of its size in synaptic transmission and asks whether the cell bodies (and dendrites) connected with large and small motor fibers have different functional properties which can be recognized by their discharge characteristics.

Muscle Fiber Types: How Many and What Kind?
TL;DR: The purpose of the present communication is to point out some of the problems involved in the classification of fibers and to add new information of value in the analysis of human biopsy material.

TL;DR: Intracellular stimulation of individual motoneurones ensured functional isolation of the muscle units innervated by them in pentobarbitone‐anaesthetized cats.

The orderly recruitment of human motor units during voluntary isometric contractions
TL;DR: The contractile properties of human motor units from the first dorsal interosseus muscle of the hand were studied during voluntary isometric contractions using recently developed techniques.
