Draw a simple schematic of a neuron and label its parts. Where does “information” usually go in and through which structure is it passed on? Where is the action potential generated?
Step by step
Solved in 2 steps with 1 images
- Neurons, particularly those in the brain, receive multiple excitatory and inhibitory signals. What is the name of the extension of the neuron at which such signals are received? How does the neuron integrate these signals to determine whether or not to generate an action potential?Diagram and label the basic features of a neuron,indicating where information is received and where it is sent.Which component of the neuron sends action potentials away from the cell body?
- Starting with the action of a neurotransmitter at the postsynaptic end of a neuron, what happens to generate an action potential to a second neuron?The neuron cell is made up of which of the following parts? A. Axon B. Dendrite C. Nucleus D. All of the AboveDescribe the synaptic junctions between one neuron and another?
- Which of the following would occur if a neuron was experimentally stimulated simultaneously at both ends? The action potentials would pass in the middle and travel to the opposite ends The action potentials would stop as they meet in the middle. The stronger action potential would override the weaker action potential. Summation would occur when the action potentials meet in the middle, resulting in a larger action potential.describe what the resting membrane potential of a cell is. What is the resting membrane potential of neurons (give units)? What are the two factors that generate the resting membrane potential? Think of scenarios that change the factors that generate the resting membrane potential and how that would change the overall resting membrane potential.If the neuron is stimulated such that its membrane potential changes to 50 mV, what is the sign of the driving force for Cl- ions and in which direction will these ions move across the membrane? Positive driving force; Cl- moves into the cell Positive driving force; Cl- moves out of the cell Negative driving force; Cl- moves into the cell Negative driving force; Cl- moves out of the cell
