Document Summary

Central nervous system: the hierarchy, cerebral cortex is the big boss and it tells everything what to do. Has direct projections to the spinal cord: thalamus, basal ganglia, pons, and cerebellum are second in command, brainstem is third in command, spinal cord is a slave system to all of the above, luigi galvani. Interested in animal electricity: attached electricity to a frogs spinal cord. When he shocked the frog it twitched: first to demonstrate the bioelectrical signal within the system of organisms which allow them to move, alpha motor neuron building block of human movement. The neuron plus the muscle fibres that interfaces: helmholtz. If a neural cell body is diseased, it influences the amplitude of nerve conduction: e. g. , amyotrophic lateral s(cid:272)le(cid:396)osis (cid:894)lou geh(cid:396)ig(cid:859)s disease): limits your ability to move. Info leaves spinal cord that innervates w an extrafusal muscle fibre by the ventral root.
