Lobe (anatomy)

In anatomy, a lobe is a clear anatomical division or extension of an organ (as seen for example in the brain, lung, liver, or kidney) that can be determined without the use of a microscope at the gross anatomy level. This is in contrast to the much smaller lobule, which is a clear division only visible under the microscope.

Interlobar ducts connect lobes and interlobular ducts connect lobules.

Examples of lobes

 * The four main lobes of the brain
 * the frontal lobe
 * the parietal lobe
 * the occipital lobe
 * the temporal lobe
 * The three lobes of the human cerebellum
 * the flocculonodular lobe
 * the anterior lobe
 * the posterior lobe
 * The two lobes of the thymus
 * The two and three lobes of the lungs
 * Left lung: superior and inferior
 * Right lung: superior, middle, and inferior
 * The four lobes of the liver
 * Left lobe of liver
 * Right lobe of liver
 * Quadrate lobe of liver
 * Caudate lobe of liver
 * The renal lobes of the kidney
 * Earlobes

Examples of lobules

 * the cortical lobules of the kidney
 * the testicular lobules of the testis
 * the lobules of the mammary gland
 * the pulmonary lobules of the lung
 * the lobules of the thymus
