1. Células satélites e fusos neuromusculares em músculos estriados de ratos desnervados por longo período / Satellite cells and neuromuscular spindles in skeletal muscles in long term denervated rats
O músculo estriado esquelético apresenta em sua constituição células satélites (CS) que se encontram em estado quiescente localizadas entre o sarcolema e a lâmina basal das fibras musculares. As CS podem ser ativadas, diferenciando em mioblastos, contribuindo para regeneração e/ou crescimento do tecido muscular. Os Fusos neuromusculares são mecanor

2. Computer modelling and simulation of human posture in standing with neuromuscular reflexes / Modelagem e simulaÃÃo do controle da postura ereta humana quasi-estÃtica com reflexos neuromusculares
This work presents a computer mathematical model of the human neuromusculoskeletal system specially designed to study the postural balance in standing. In addition to the extrafusal muscle tissue properties commonly used in traditional muscle models applied to study human movement and posture, this model includes two components physiologically important of p

3. Sources of innervation of the neuromuscular spindles in sternomastoid and trapezius.
The sources of innervation of neuromuscular spindles in sternomastoid and trapezius have been investigated in rats and mice, by degeneration experiments. The entire motor supply, both extrafusal and intrafusal, to both muscles, was from the spinal accessory nerve. The sensory supply to the spindles in sternomastoid and rostral trapezius was from cervical spi

4. An ultrastructural study of neuromuscular spindles in normal mice: with reference to mice and man infected with Mycobacterium leprae.
Mycobacterium leprae have been found within muscle spindles in mice, using electron microscopy, and in man, using light microscopy. Their mode of entry clearly is important. It may be via capsular cells, capillaries or nerves. For this reason muscle spindles from normal mice were studied by electron microscopy with special reference to the capsule and the re

5. Sheathing of muscle fibres at neuromuscular junctions and at extra-junctional loci in human extra-ocular muscles.
Profuse sheathing of muscle fibres was noticed by chance when studying receptors in samples of extra-ocular muscle taken from orbits of six patients after eye enucleation or in the treatment of squint. The sheaths, previously unreported in any skeletal muscle, were examined by light and electron microscopy and their incidence determined. Muscle spindle capsu

6. ErbB2 Is Required for Muscle Spindle and Myoblast Cell Survival
Signaling mediated by ErbB2 is thought to play a critical role in numerous developmental processes. However, due to the embryonic lethality associated with the germ line inactivation of erbB2, its role in adult tissues remains largely obscure. Given the expression of ErbB2 at the neuromuscular junction, we have created a muscle-specific knockout to assess it

7. Observations on the structure of the dorsal muscle in the bottle-nose dolphin (Tursiops truncatus).
The dorsal muscle of five South Australian bottle-nose dolphins has been studied. The ultrastructure and cytochemistry of the red, white and intermediate fibres were essentially similar to those of other mammalian skeletal muscles. Two features of special interest were: (a) the large number of lipid droplets in the red muscle fibres, and (b) the presence of

8. Neuregulin induces the expression of transcription factors and myosin heavy chains typical of muscle spindles in cultured human muscle
Neuregulin (NRG) (also known as ARIA, GGF, and other names) is a heparin sulfate proteoglycan secreted into the neuromuscular junction by innervating motor and sensory neurons. An integral part of synapse formation, we have analyzed NRG-induced changes in gene expression over 48 h in primary human myotubes. We show that in addition to increasing the expressi

9. A quantitative study of skeletofusimotor innervation in the cat peroneus tertius muscle.
1. Physiological tests were used to identify skeletofusimotor or beta axons to the cat peroneus tertius muscle in order to assess the proportion of beta axons in the motor supply to this muscle. 2. Static beta axons (beta S) were identified by: (a) observation of a delay between the complete block of extrafusal contraction and the failure of spindle activati
