You are given a drug to test and find that it increases the resting membrane potential and frequency of action potential firing. What are two possible drug targets and how could you differentiate them? How can you predict the effects of a change in matter or energy availability on ecosystems?
Fully describe the action potential of a muscle. Describe RMP and the generation of an action potential. Explain the different components of water potential. Describe how the membrane potential compares to the resting potential. What ions are in action potential? How does the action pot...
Briefly describe what resting membrane potential of nerves is. What is the difference between tubular reabsorption and tubular secretion? What are the differences between sympathetic and parasympathetic systems. Which one is active during fed states? What NT...
When the cell membrane of a neuron changes its permeability, allowing more positively charged neurons to flow into the cell and other ions flow out, the neuron has reached its: a) action potential. b) quiet potential. c...
Discuss how resting potentials are generated in neurons. Explain the relationship between various ion channels and repolarization, and hyperpolarization of the membrane. Explain how the human head and the brain are adapted to the well being of a man. Provide a hypothesis explaining how the a...
When nerve cells are at rest, there is a resting membrane potential (RMP; phase #1 on the graph) for the neuron cell membrane. Describe how the RMP is generated. Describe evidence that supports the hypothesis that cell membranes are fluid. Des...
Describe how the action of particular muscles changes lung volume and pressure leading to air movement into the lungs under resting conditions. Explain why normal expiration is a passive process while a maximal or forced expiration is an active process. ...
Describe the mechanisms of development of resting potential of cell membrane. Describe how the emergent properties of the cells of the gastrula direct embryonic development. Describe the role of cell in an organisms. How are germ cells set apart from the cells that are constructing the physi...
Describe how the selective permeability of a neuron cell membrane establishes a resting membrane potential. Describe the transmission of signals across the synapse. Explain the action potential of the cardiac muscle cells, depolariz...
Discuss how resting potentials are generated in neurons. Explain the relationship between various ion channels and repolarization, and hyperpolarization of the membrane. Give examples of sympathetic and parasympathetic effects. Explain what happens at a chemical synapse...
