A pancreatectomy can be performed as a treatment for pancreatic cancer, pancreatic tumors (pre-malignant), chronic pancreatitis, or when the pancreas has been severely damaged by injury. Removing part of or the entire pancreas may cause a loss of pancreatic digestive enzyme production, leading to EPI.
Question: When a nerve fiber is polarized, the concentration... When a nerve fiber is polarized, the concentrationof: A. sodium and potassiumions is higher on the inside of its membrane. B. sodium ions is higher on the inside of its membrane and potassium ions are higher on the outside.
Nerve Impulse Conduction. A nerve impulse begins conduction as electrical impulses, initiated by the brain, travel down through nervous system cells. The electricity causes a change in polarity by opening channels to move positive sodium or potassium ions in or out. Positive molecules are stored in membranes guarded by gated channels.
