Pathological Changes in Voluntary Muscles in General Diseases

Pathological changes associated with white striping in broiler breast muscles.

White striping is a condition in broiler chickens characterized grossly by the occurrence of white striations, seen parallel to the direction of muscle fibers, on broiler breast fillets and thighs. Based on visual evaluation of the intensity of white striping, breast fillets can be categorized into normal (NORM), moderate (MOD), and severe (SEV) categories. This study was undertaken to evaluate...

A Critical Review: Primary Diseases of Voluntary Muscles.

THE voluntary muscular system forms in an average male about 43 per cent. of the total body weight. It is a very uniform system and is composed of aggregations of individual muscle fibres each of which are complex multinucleated cells, consisting of a sarcolemmal sheath and its nuclei, a motor end plate, and contractile substance. This system is affected by a large group of primary diseases, i....

Excitability changes in human corticospinal projections to forearm muscles during voluntary movement of ipsilateral foot.

Excitability of the H-reflex in the relaxed flexor carpi radialis (FCR) muscle was tested during voluntary oscillations of the ipsilateral foot at five evenly spaced delays during a 600 ms cycle. In some experiments the H-reflex was conditioned by transcranial magnetic stimulation (TMS). With the hand prone, the amplitude of the FCR H-reflex was modulated sinusoidally with the same period as th...

Physiological changes in ageing muscles.

Physiological studies have been made of extensor digitorum brevis muscles in 28 healthy subjects aged between 60 and 96. Within this elderly population there was evidence of muscle wasting and weakness. These changes were shown to result from a loss of functioning motor units. The surviving motor units were often enlarged and tended to have relatively slow twitches. In some subjects the maximum...
