NOTE ON MUSCLE-SPINDLES IN PSEUDO-HYPERTROPHIC PARALYSIS

Muscle Spindles in Phasic and Tonic Muscle.

Comparisons were made of muscle spindle structure between phasic and tonic muscles stained by the gold chloride method. The most significant difference was in the ring diameter of the sensory nerve terminals wrapped around the nuclear bags. In tibialis anterior it was largest, in gastrocnemius intermediate, and in soleus smallest. This order corresponds to the contraction time, tibialis anterio...

Stimulation of muscle spindles

"Pseudo" hypertrophic neuropathy of childhood.

A 9 year old boy had chronic progressive motor-sensory neuropathy that started in early infancy. He had enlarged nerves and pes cavus deformity. Motor conduction studies showed very dispersed, polyphasic compound muscle action potentials with conduction velocities around 2 m/s. A sural nerve biopsy showed severe loss of myelinated fibres. Two months of treatment with corticosteroids restored mu...

A note on pseudo - symplectic Runge - Kutta

In 1], the concept of pseudo-symplecticness was introduced in order to construct explicit Runge-Kutta methods which mimic symplectic ones. Of particular interest are methods of order (p; 2p),-i.e. of order p and pseudo-symplecticness order 2p-, for which the growth of the global error remains linear. The aim of this note is to show the existence of methods of orders (4; 8) and (5; 10) with a mi...
