This lesson describes the organisation of the mammalian nervous system, focusing on the CNS and the numerous divisions and subdivisions of the PNS. The PowerPoint and accompanying resource have been planned to cover the content of points 9.4 (i) and (iv) of the Edexcel A-level biology B specification.
The lesson begins by challenging the students to recognise 6 organ systems from their descriptions, with the final description relating to the nervous system. A prior knowledge check of the classification topic introduces the lesson topic as the structure of the mammalian nervous system and then the lesson moves through the different divisions, completing the diagram in the cover image as each one is explored. The brain, spinal cord, neurones and autonomic nervous system are described in depth in upcoming lessons, so this lesson has been designed to introduce key information and to challenge students to build on the details they have from GCSE studies!

Topic 9: Control systems (Edexcel A-level Biology B)
This bundle contains 19 lessons which are engaging and highly detailed in order to cover the difficult content as set out in topic 9 (Control systems) of the Edexcel A-level Biology B specification. The lesson PowerPoints and accompanying resources contain a wide variety of tasks which cover the following specification points: * Homeostasis is the maintenance of a state of dynamic equilibrium * The importance of maintaining pH, temperature and water potential in the body * The meaning of negative feedback and positive feedback control * The principles of hormone production by endocrine glands * The two main modes of action in hormones * The organisation of the mammalian nervous system into the CNS and PNS * The structure of the spinal cord * The location and functions of the main parts of the brain * The division of the autonomic nervous system into the sympathetic and parasympathetic systems * The transport of sodium and potassium ions in a resting potential * The formation of an action potential and the propagation along an axon * Saltatory conduction * The function of synapses * The formation and effects of excitatory and inhibitory postsynaptic potentials * The structure of the human retina * The role of rhodopsin * The distribution of rods and cone cells * The control of heart rate by the autonomic nervous system * The gross and microscopic structure of the kidney * The production of urea in the liver and its removal from the blood by ultrafiltration * Selective reabsorption in the proximal tubule * Water reabsorption in the loop of Henle * Control of mammalian plasma concentration * The differences between ectotherms and endotherms * The regulation of temperature by endotherms If you would like to sample the quality of this lesson bundle, then download the homeostasis, mammalian nervous system, resting and action potentials and the formation of urea and ultrafiltration lessons as these have been uploaded for free.
