Thickening of axon leads to: (A) Increased speed of conduction, (B) Decreased speed of conduction, (C) Increased absolute refractory period, (D) Unmyelination
Answer is A. Thickening of axon leads to increased speed of conduction as the action potential velocity increases propoionately with axon diameter. Ref: guyton and hall textbook of medical physiology 12 edition page number:76,77,78
