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.
Fig. 2-17, p. 43 Recording Neural Signals - continued Electrical signals or action potentials occur when: permeability of the membrane changes Na+ flows into the fiber making the neuron more positive K+ flows out of the fiber making the neuron more negative This process travels down the axon in a propagated response Figure 2.7 (a) When a nerve fiber is at rest, there is a difference in charge of -70 mV between the inside and the outside of the fiber.
