What is polarization?
Block 3 Lecture 2 - The Synapse and Synaptic Transmission 1. Identify and describe the synapse Synapse - joining of cell Presynaptic neuron - toward the synapse Postsynaptic neuron - away from the synapse Axosomatic synapse - attached to dendrite Axodendritic synapse - attached to soma Axoaxonal synapse - attached at axon hillock - greatest influence dude to voltage decay of graded potential 2. Compare and contrast electrical and chemical synapses Electrical synapse - no synaptic delay - gap junctions - no directionality, can go either way - common in lower invertebrate (ie. lobsters) and early development - less common in humans (stereotyped eye movement) Chemical Synapse - synaptic delay (0.3 - 5 ms)(has to travel across synaptic cleft) - axon terminal - common i
