IBDP > CORE TOPICS > 6.5 NEURONS AND SYNAPSES
LESSON PLAN
DAY 1
6.5.U1: Neurons transmit electrical impulses (Oxford Biology Course Companion page 319).
6.5.U2: The myelination of nerve fibres allows for saltatory conduction (Oxford Biology Course Companion page 320).
6.5.U3: Neurons pump sodium and potassium ions across their membranes to generate a resting potential
6.5.U4: An action potential consists of depolarization and repolarization of the neuron.
6.5.U5: Nerve impulses are action potentials propagated along the axons of neurons.
6.5.U9: A nerve impulse is only initiated if the threshold potential is reached.
6.5.S1: Analysis of oscilloscope traces showing resting potentials and action potentials.
6.5.U6: Propagation of nerve impulses is the result of local currents that cause each successive part of the axon to reach the threshold potential.

DAY 2
6.5.U7: Synapses are junctions between neurons and between neurons and receptors or effector cells.
6.5.U8: When presynaptic neurons are depolarized they release a neurotransmitter into the synapse.
6.5.A1: Secretion and reabsorption of acetylcholine by neurons at synapses.
6.5.A2: Blocking of synaptic transmission at cholinergic synapses in insects by binding of neonicotinoid pesticides to acetylcholine receptors.
