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 impulses that originate in the central nervous system cause muscles to contract. Both neurons and muscle tissue conduct electrical current by moving ions across cellular membranes. A motor neuron ends in a synapse with a muscle fiber.The neuron releases acetylcholine and transfers the action potential to the muscle tissue. The signal will travel through the tissue and trigger the contraction of individual sarcomeres. One synapse generally controls an entire muscle fiber.One motor neuron usually controls several adjacent muscle fibers.he neuron releases acetylcholine and transfers the action potential to the muscle tissue. The signal will travel through the tissue and trigger the contraction of individual sarcomeres.
