A new reduced mathematical model to simulate the action potential in end plate of skeletal muscle fibers
Usually mathematicians use Hodgkin-Huxley model or FitzHug-Nagumo model to simulate action potentials of skeletal muscle fibers. These models are electrically excitable, but skeletal muscle fibers are stimulated chemically. To investigate skeletal muscle fibers we use a model with six ordinary differential equations. This dynamical system is sensitive to initial value of some variables so it is...
متن کاملActive phase of frog's end-plate potential.
IT HAS BEEN CONSIDERED that the end-plate potential (e.p.p.) is generated by the brief ionic flux across the end-plate membrane and the later slowly declining phase of the e.p.p. is due to the dissipation of the charge along and across the muscle membrane. This consideration was supported by some authors. Kuffler (21) observed with a single nerve-muscle preparation that the later slowly decayin...
متن کاملCholinesterase activity of motor end plate in human skeletal muscle.
The activity and properties of cholinesterase of the motor end plate in human intercostal muscle were studied in the isolated muscle membrane. This preparation was used because cholinesterase activity of the membrane preparation was localized in the motor end plate without contamination of cholinesterase of other muscle components. Under the experimental conditions, cholinesterase in a human en...
متن کاملMuscle fiber and motor end plate involvement in the extraocular muscles of the myotonic mouse.
The extraocular muscles of the C57BL/6Jdy-2j myotonic mouse were studied by phase and electron microscopy. The most susceptible ocular muscle was the levator palpebrae; the other muscles manifested scattered abnormalities to varying degrees. Central nucleation and fiber splitting were prominent. Junctional abnormalities consisted of a reduction in post-junctional folding, excessive numbers of a...
متن کاملNew Observations on the Mammalian Growth Plate
Chondrocytes at the lower zone of the growth plate must be eliminated to facilitate longitudinal growth; this is generally assumed to involve apoptosis. We attempted to provide definitive electron-microscopic evidence of apoptosis in chondrocytes of physes and chondroepiphyses in the rabbit. We were, however, unable to find a single chondrocyte with the ultrastructure of ‘classical’ apoptosis i...
