Student learn
- identify that a nerve is a bundle of neuronal fibres
- identify neurones as nerve cells that are the transmitters of signals by electro-chemical changes in their membranes
- define the term ‘threshold’ and explain why not all stimuli generate an action potential
- identify those areas of the cerebrum involved in the perception and interpretation of light and sound
- explain, using specific examples, the importance of correct interpretation of sensory signals by the brain for the coordination of animal behavior
- perform a first-hand investigation using stained prepared slides and/ or electron micrographs to gather information about the structure of neurones and nerves
- perform a first-hand investigation to examine an appropriate mammalian brain or model of a human brain to gather information to distinguish the cerebrum, cerebellum and medulla oblongata and locate the regions involved in speech, sight and sound perception
- present information from secondary sources to graphically represent a typical action potential
