This is a brief narrated animation on how the neurotransmitter from the pre-synaptic neuron is released into the synaptic cleft and how its subsequent binding to receptors in the postsynaptic neuron brings about the transmission and propagation of the nerve impulse.
• Users will initially view electron micrograph of pre- and post-synaptic neurons and the synapse between them.
• User will see and hear narration of how the neurotransmitter in the pre-synaptic neuron is released into the synaptic cleft, and how its binding with the receptors in the post-synaptic neuron brings about the propagation of action potential
• User will learn what happens to the neurotransmitter after the action potential is generated
Target Student Population:
Middle School, High School, College General Ed, College Lower Division
Prerequisite Knowledge or Skills:
Knowledge of some biological terms associated with the nervous system
Type of Material:
• In-class lecture supplement
Evaluation and Observation
• Material is accurate.
• Micrograph clearly depicts the object being described, in this case the pre- and post-synaptic neurons and the synaptic clefts.
• Narration is clear and concise.
• Illustrates how neurotransmitters carry signal across synaptic cleft. • Illustrates role of calcium in neurotransmitter release.
• Movement of ions across membrane driving nervous impulse is not well illustrated.
Potential Effectiveness as a Teaching Tool
• Narration helps students understand the relatedness of the topics as depicted in the animation.
• Narration helps user focus on key concept, in this case the events that take place in the synapse.
• Graphics and animation provide a visual and auditory enhancement for visual and auditory learners.
• Illustrates a complex concept clearly. Easy to follow with good narration.
• Could produce assignments based on the animation.
• No assignments or test questions are provided.
• A little simplistic with regards to ion transport across the membrane driving nervous impulses, which is key to this concept.
Ease of Use for Both Students and Faculty
• Narrations and animations played simultaneously without problems.
• Information is easy to understand.
