- What is a synapse? Explain the difference between an excitatory and an inhibitory synapse.View the University of Michigan Webscope (http://openstaxcollege.org/l/nervefiber) to see an electron micrograph of a cross-section of a myelinated nerve fiber. The axon contains microtubules and neurofilaments, bounded by a plasma membrane known as the axolemma. Outside the plasma membrane of the axon is the myelin sheath, which is composed of the tightly wrapped plasma membrane of a Schwann cell. What aspects of the cells in this image react with the stain that makes them the deep, dark, black color, such as the multiple layers that are the myelin sheath?A(n)______neuron has one axon and one____ dendrite extending directly from the cell body. unipolar bipolar multipolar pseudounipolar

Action potential arrives 6. lon channel closes the obeicos in the bo y belo M (A nWhich statement is TRUE about the synapse? Neurotransmitters shuttle the signal back and forth between the pre- and post-synaptic cell. The pre-synaptic cell and post-synaptic cell are in direct contact, allowing the electrical signal to seamlessly flow from one to the other. The action potential jumps from the pre-synaptic cell into the post-synaptic cell. The action potential ends in the pre-synaptic cell and neurotransmitters carry the signal across the synaptic cleft to the post-synaptic cell.
- Events in Synaptic Signal Transmission 1. Neurotransmitters are released into the synaptic cleft. 2. Neurotransmitters bind to ion channels. 3. Sodium ions enter into the dendrites. 4. Neurotransmitters are returned to the axon terminal, broken down by the enzymes or diffused away from the synapse. 5. Action potential arrives in axon terminal. 6. Synaptic vesicles containing the neurotransmitters fuse with the presynaptic membrane. 7. lon channels open. The sequence in which the events numbered above are involved in the signal transmission across the synapse is ,andWhich of these alternatives shows the correct order for a neuron that is leaving the spine? Think of the neuron starting at the spinal cord and an exiting the spine, going to your chest. What would be the path? It would travel out of the spine into the spinal nerve, past the dorsal branch and into the rootlet of the chest. into a spinal nerve, then into a ventral root and then into an anterior branch past a rootlet, into a ventral branch, past a dorsal root, and then to the chest past a rootlet, into a ventral root, into a spinal nerve and then into an anterior branchThe following table summarizes the characteristics of four different neurons.

The order in which this happens comes down to the timing/speed/kinetics of the different gates on the channels. Put the following events in the order they occur after a neuron reaches threshold voltage. 1. Voltage-gated K+ channels finish closing their gate. 2. Voltage-gated Na+ channels open their activation gate, increasing Na+ permeability. 3. Voltage-gated Na+ channels close their inactivation gates, reducing Na+ permeability. 4. Voltage-gated K+ channels open their gate, increasing K+ permeability. 5. Voltage-gated Na+ channels reset to their original conformation.
