This lesson focuses on the structure of the spinal cord but also introduces key nervous system structures to prepare students for upcoming topic 9 lessons. The PowerPoint and accompanying resource have been planned to cover the content of point 9.4 (ii) of the Edexcel A-level biology B specification.
As shown on the cover image, the lesson begins with a challenge, where students must use their knowledge of content from earlier topics to reveal 5 numbers that add up to 33. They will learn that this is the normal number of vertebrae in the human vertebral column and this leads into the recognition that these bones act to surround and protect the spinal cord. The meninges are introduced and then a quick quiz round is used to reveal the term, grey matter. Students will see that this is found in the centre of the spinal cord and is surrounded by an outer region of white matter. The idea of myelination is introduced, and initial details provided about the increased conductance speed in myelinated neurones because of saltatory conduction. Moving forwards, students will meet the terms dorsal and ventral and see on a diagram that nerves enter and leave the cord by these roots. The role of cerebrospinal fluid is explored and a series of exam-style questions are used to challenge their knowledge from topic 2 and 6 as well as their mathematical skills. The answers are embedded into the PowerPoint to allow the students to assess their progress.
The lesson finishes with the introduction of the cauda equina as the bundle of nerves at the distal end of the spinal cord.

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.
