The exocrine secretion of the pancreas is delivered to the duodenum via the:
Answer: Hepatopancreatic ampulla (of Vater)
The pancreatic duct joins the common bile duct at the hepatopancreatic ampulla, which opens into the duodenum.
Action potentials propagate along unmyelinated nerve fibers by which mechanism?
Answer: Continuous conduction along the entire axon membrane
Unmyelinated fibers conduct action potentials continuously along the axon membrane, slower than saltatory conduction in myelinated fibers.
The hormone aldosterone from the adrenal cortex acts on the kidney to:
Answer: Increase Na+ reabsorption and K+ excretion in collecting ducts
Aldosterone upregulates Na+/K+-ATPase and ENaC channels in collecting duct principal cells, retaining Na+ and excreting K+.
Which plasma protein is primarily responsible for maintaining oncotic pressure and preventing edema?
Answer: Albumin
Albumin, the most abundant plasma protein, exerts the greatest oncotic pressure, retaining fluid in the vascular compartment.
During swallowing (deglutition), the epiglottis covers the glottis primarily to:
Answer: Prevent food and liquid from entering the larynx and trachea
The epiglottis folds backward over the glottis during swallowing to direct food into the esophagus and protect the airway.
The zona glomerulosa of the adrenal cortex secretes which hormone?
Answer: Aldosterone
The outermost zona glomerulosa produces mineralocorticoids, primarily aldosterone, which regulates sodium and potassium balance.
Which component of the ECG represents ventricular repolarization?
Answer: T wave
The T wave reflects ventricular repolarization as ventricles return to their resting membrane potential after contraction.
