College Anatomy and Physiology
What is homeostasis?
  1. fluctuate greatly between very high and low values
  2. ingestion of enough food to satisfy hunger
  3. tendency of the body to maintain a stable environment

College Nervous and Endocrine Systems
Threshold potential is of great significance in the physiology of neurons because if threshold is not reached,                                                                                                   .
  1. the action potential will be "inversed", with a flux of sodium out of the cell rather than into it
  2. the neuron cannot regain its resting potential
  3. positive-feedback depolarization will not occur
  4. an action potential will be triggered
College Nervous and Endocrine Systems
What do we mean by action potential?
  1. a sudden reversal of the sodium-potassium pump
  2. a sudden increase in speed by the sodium-potassium pump
  3. a traveling wave of depolarization in the neuron membrane
  4. a brief neutralization of the charges on sodium and potassium ions
College Nervous and Endocrine Systems

  1. axon hillock
  2. dendritic membrane
  3. axonal membrane
  4. synaptic terminals
College Environmental Science
