Histochemical Characteristics of Muscle Fiber Types in the Posterior Cricoarytenoid Muscle

Annals of Otology, Rhinology & Laryngology, 1981
The muscle fiber type composition of the human posterior cricoarytenoid muscle (PCA) was examined using a large battery of histochemical techniques. Staining for myosin ATPase (pH 9.9) indicated that the muscles were composed of 52% ± 11.8 SD type 1 (slowly contracting) fibers and 48% ± 11.9 SD type 2 (rapidly contracting) fibers.

Developmental pattern of muscle fiber types in human ventilatory muscles

Journal of Applied Physiology, 1978
Premature infants tolerate respiratory loads poorly. This may reflect incomplete development of the ventilatory muscles (VM) causing poor resistance to fatigue. To study the developmental pattern of human VM, 31 postmortem specimens of diaphragm and intercostal muscles were obtained.

Composition of Muscle Fiber Types in Rat Rotator Cuff Muscles

The Anatomical Record, 2016
ABSTRACTThe rat is a suitable model to study human rotator cuff pathology owing to the similarities in morphological anatomy structure. However, few studies have reported the composition muscle fiber types of rotator cuff muscles in the rat. In this study, the myosin heavy chain (MyHC) isoforms were stained by immunofluorescence to show the muscle ...

Muscle Fiber-Type Distribution Pattern in the Human Cricopharyngeus Muscle

Dysphagia, 2002
Our previous studies described that the human cricopharyngeus (CP) is composed of two neuromuscular compartments (NMCs), horizontal and oblique. The present study was designed to explore the differences in muscle fiber-type distribution between the NMCs within the human CP and to examine the oxidative capacity of the muscle fibers. Seven adult human CP

The development of muscle fiber type identity in zebrafish cranial muscles

Anatomy and Embryology, 2005
Cranial skeletal muscles underlie breathing, eating, and eye movements. In most animals, at least two types of muscle fibers underlie these critical functions: fast and slow muscle fibers. We describe here the anatomical distribution of slow and fast twitch muscle in the zebrafish (Danio rerio) head in the adult and at an early larval stage just after ...

Canine muscle fiber types and susceptibility of masticatory muscles to myositis

Muscle & Nerve, 1981
AbstractThe myofiber type composition was studied in 42 different muscles of the dog to determine if there are unique features that might explain the preferential involvement of the muscles of mastication by inflammatory myopathies. The principal myofiber types for most muscles studied were type 1 and type 2A and, to a lesser extent, type 2C, wherease ...

Specific innervation of muscle fiber types in a developmentally polyinnervated muscle

Developmental Biology, 1985
In neonatal rabbit soleus muscle, different motor units were found to contract with widely varying time courses. Analysis of these data suggest that individual motor units are largely homogeneous for muscle fiber type despite the presence of extensive polyinnervation at birth.

Muscle fiber type composition of the rat hindlimb

American Journal of Anatomy, 1984
AbstractThe purpose of this study was to estimate the absolute and relative masses of the three types of skeletal muscle fibers in the total hindlimb of the male Sprague‐Dawley rat (Rattus norvegicus). For six rats, total body mass was recorded and the following weights taken from dissection of one hindlimb: 32 individual major muscles or muscle parts,

Fiber type composition of monkey forearm muscle

The Anatomical Record, 1985
AbstractHistochemical staining methods were applied to selected superficial forearm muscles of Macaca mulatta monkeys. The muscles were analyzed with regard to relative percentage distribution of different fiber types. In extensor carpi radialis brevis, extensor carpi radialis longus, and palmaris longus there was an even dispersion of each fiber type ...
