Step by step
Solved in 2 steps
- What is a synapse? Explain the difference between an excitatory and an inhibitory synapse.A neuron responds to adequate stimulation with _______, a type of self-propagating signal.Assume presynaptic excitatory neuron A terminates on a postsynaptic cell near the axon hillock and presynaptic excitatory neuron B terminates on the same postsynaptic cell on a dendrite located on the side of the cell body opposite the axon hillock. Explain why rapid firing of presynaptic neuron A could bring the postsynaptic neuron to threshold through temporal summation, thus initiating an action potential, whereas firing of presynaptic neuron B at the same frequency and the same magnitude of EPSPs may not bring the postsynaptic neuron to threshold.
- A/An _____ synapse is formed when a presynaptic neuron synapses with the cell body of a postsynaptic neuronDiscuss the activity, structures and chemicals of both the neural axon and receptor. And a discussion about the synapse should begin with a definition and a comparison of the two categories.If a postsynaptic cell has synapses from five different cells, and three cause EPSPs and two of them cause IPSPs, give an example of a series of depolarizations and hyperpolarizations that would result in the neuron reaching threshold.
