Biol 235 assignment 2 - Study guides, Class notes & Summaries

2. What are EPSPs and IPSPs, and how are they produced? Explain how these electrical currents are used in spatial and temporal summation to initiate or inhibit the generation of an action potential. EPSPs means Excitatory and Inhibitory ? Postsynaptic Potentials while IPSPs means Inhibitory Postsynaptic Potential (IPSP). A neurotransmitter causes either an excitatory or an inhibitory graded potential. A neurotransmitter that causes depolarization of the postsynaptic membrane is excitatory ...

Maintenance of calcium ion is critical to neurological, cardiac and skeletal muscle function. Consider the roles of 2 hormones involved in the regulation of the concentration of calcium ions in the blood. Parathyroid hormone increases the concentration of calcium ions in the blood, while calcitonin decreases the concentration. Based on this information predict the bod’s response to restore calcium balance if a person swallowed 100 antacid tablets made up of a calcium compounds in 10 minute...
