Why does the cerebral cortex contain so many folds? ” To increase the surface area and also by creating more space for information processing ”3. What is a nerve impulse? ” A nerve impulse is an electrical signal transmitted from one cell to another for communication. ”4. What are Schwann cells and what do they form? ” They are variety of glial cells which keep alive the peripheral nerve fibers. Schwann cells form the myelin sheath. ”5. What is an all-or-none response? ” It is a type of response that may either be complete and full of intensity or totally absent, based on the strength of the stimulus. There is no incomplete response ”6. What two effects might neurotransmitters have? ” Inhibition or Excitation Experiment 1: Microscopic Anatomy of the Nervous System Post-Lab Questions ”1.
