How do NMDA synapses differ from AMPA synapses? How do they change over time?

What distinguishes a steroid receptor from a receptor tyrosine kinase receptor or a G-protein-coupled receptor?

Many neurons have only a single axon, but many terminals at the end of the axon. How does this end structure of the axon support its function?

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.

What two types of macromolecules are the main components of myelin? carbohydrates and lipids proteins and nucleic acids lipids and proteins carbohydrates and nucleic acids

Describe how the sensory-somatic nervous system reacts by reflex to a person touching something hot. How does this allow for rapid responses in potentially dangerous situations?

Which type of neuron, based on its shape, is best suited for relaying information directly from one neuron to another? Explain why.

Which of the following does not contribute to propagation of action potentials? a. As the area outside the membrane becomes negative, itattracts ions from adjacent regions; as the inside of the membrane becomes positive, it attracts negative ions from nearby in the cytoplasm. These events depolarize nearby regions of the axon membrane. b. The refractory period allows the impulse to travel in only one direction. c. Each segment of the axon prevents the adjacent segments from firing. d. The magnitude of the action potential stays the same as it travels down the axon. e. Up to a limit, increasing the intensity of the stimulus increases the number of action potentials.

The conscious perception of pain is often delayed because of the time it takes for the sensations to reach the cerebral coitex. Why would this be the case based on propagation of the axon potential?

What does it mean for an action potential to be an all or none event?
