From the National Learning Network Materials' Biology collection, this interactive resource looks at the nervous control of muscles. Animations look at neurotransmitters and the transmission of impulses at synapses and the neuromuscular junction. Muscle fibre motor units and the control of muscle contraction is illustrated.
From the National Learning Network Materials' Biology collection. This interactive resource shows how nerve signals, or action potentials, are transmitted along a nerve cell. Students see the cell's resting potential and how an action potential is generated and propogated along a nerve cell.
