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.
