Nervous System: Synapses and Nervous Control of Muscle
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.
Nervous System: Responding to Stimuli
This unit of learning materials from the National Learning Network Materials' Biology collection introduces the structure and function of the human nervous system. Animations and illustrations show the structure of nerve cells, transmission of signals at a synapse, a reflex arc, sense organs and effectors.
Nervous System: Action Potentials
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.

Cells of Animals, Plants and Bacteria
This interactive resource, from the National Learning Network Materials' Biology collection, begins by looking at the workings of light and electron microscopes. Through illustrations and quizzes, students investigate the structure and function of animal, plant and bacterial cells.
Cells, Tissues and Organs
This unit of material is from the National Leaning Network Materials' Biology collection. Interactives and animations explore cell structure, specialisation and functions. Students also look at different tissues and see how they can be organised into organs.
Enzyme Action
This unit of learning material, from the National Leaning Network Materials' Biology collection, explains enzymes and enzyme action. Animations illustrate the lock and key model of enzyme action. Students see how temperature and pH influence the enzyme's active site and therefore the rate of reaction.
