Sliding filament theory - Study guides, Class notes & Summaries

Is skeletal muscle always attached to bone? - ANSWER no, example is the tongue the sliding filament theory - ANSWER -sufficient evidence to prove theory -upon stimulation, the myosin heads bind to actin and sliding begins -thin filaments slide past thick ones -Z-disc becomes shorter -heads will leave one binding site and move to the next -elastic fibers bring the thin filaments back to their original state (elasticity) -A band stays the same -sarcomere shortens -myosin section becomes...

MUSCLE FIBERS initiation of skeletal muscle contraction - Answer 1. Events in the CNS: areas of the brain responsible for voluntary movement and the descending tracts in the spinal cord. 2. Events in neuromuscular junction: is a point of synaptic contact b/w somatic motor neurons and individual muscle fibre. 3. Excitation- contraction coupling: an AP initiated in the skeletal muscle fibre results in an increase in intracellular Ca2+. 4. Ca2+ signal 5. Contraction relaxation cycle: broken...
