Product Description
This 50-slide powerpoint presentation covers 'Topic 6.5 - Neurons & Synapses' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note.

The topic has been divided into four sections:

     • A - Neurons
     • B - Action Potentials
     • C - Synapses
     • D - Acetylcholine

The presentation itself contains minimal information as it is intended to be used with teacher guidance. There are sometimes 'Video' throughout which link to relevant and informative YouTube content. The slides are formatted to be visually pleasing and to also print well for handouts or revision. Please see the preview file (first 8 slides) for an idea of the aesthetic and level of detail in the presentation. The relevant 'Essential Knowledge' can be found below.

Suggested Use:

I have had success using these presentations to review topics after students have been exposed to the material at home. I typically have the class read relevant material (book, site, etc.) and then watch the videos the day before introducing a topic. During the class period, I use the slides to structure the discussion around the IB Bio Understandings. The remaining class time is spent reinforcing the knowledge or working on activities, written test practice, or nature of science.

**These presentations are based on the IB Biology Course Guide and do not follow any textbook

As always, please let me know if you have any suggestions for improvements. These are always a work in progress!

==============================

Learning Objectives:

U1: Neurons transmit electrical impulses.
U2: The myelination of nerve fibres allows for saltatory conduction.
U3: Neurons pump sodium and potassium ions across their membranes to generate a resting potential.
U4: An action potential consists of depolarization and repolarization of the neuron.
U5: Nerve impulses are action potentials propagated along the axons of neurons.
U6: Propagation of nerve impulses is the result of local currents that cause each successive part of the axon to reach the threshold potential.
U7: Synapses are junctions between neurons and between neurons and receptor or effector cells.
U8: When presynaptic neurons are depolarized they release a neurotransmitter into the synapse.
U9: A nerve impulse is only initiated if the threshold potential is reached.
A1: Secretion and reabsorption of acetylcholine by neurons at synapses.
A2: Blocking of synaptic transmission at cholinergic synapses in insects by binding of neonicotinoid pesticides to acetylcholine receptors.
S1: Analysis of oscilloscope traces showing resting potentials and action potentials.
