This is a fully-resourced revision lesson that includes a detailed and engaging powerpoint (81 slides) that uses a combination of exam questions, understanding checks, quick differentiated tasks and quiz competitions to enable students to assess their understanding of the content found within Topic 8 (Grey Matter) of the Pearson Edexcel A-level Biology A (Salters Nuffield) specification.
The specification points that are tested within the lesson include:
- Know the structure and function of sensory, relay and motor neurones including the role of Schwann cells and myelination.
- Understand how the nervous systems of organisms can cause effectors to respond to a stimulus.
- Understand how the pupil dilates and contracts.
- Understand how a nerve impulse (action potential) is conducted along an axon including changes in membrane permeability to sodium and potassium ions and the role of the myelination in saltatory conduction.
- Know the structure and function of synapses in nerve impulse transmission, including the role of neurotransmitters, including acetylcholine.
- Understand how IAA bring about responses in plants to environmental cues
- Know the location and functions of the cerebral hemispheres, hypothalamus, cerebellum and medulla oblongata in the human brain.
- Understand how magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), positron emission tomography (PET) and computed tomography (CT) scans are used in medical diagnosis and the investigation of brain structure and function.
- Understand how imbalances in certain, naturally occurring brain chemicals can contribute to ill health, including dopamine in Parkinson’s disease and serotonin in depression, and to the development of new drugs.
- Understand the effects of drugs on synaptic transmissions, including the use of L-Dopa in the treatment of Parkinson’s disease and the action of MDMA in Ecstasy.
Students will be engaged by the numerous quiz rounds such as “From NUMBERS 2 LETTERS” and “COMMUNICATE the WORD” whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual A-level terminal exams
