ear lobe  the lower fleshy part of the external ear.

frontal lobe  the rostral (anterior) portion of the cerebral hemisphere.

hepatic lobes  the lobes of the liver, designated the right and left and the caudate and quadrate.

insular lobe  insula.

occipital lobe  the most posterior portion of the cerebral hemisphere, forming a small part of its dorsolateral surface.

parietal lobe  the upper central portion of the cerebral hemisphere, between the frontal and occipital lobes, and above the temporal lobe.

polyalveolar lobe  a congenital disorder characterized in early infancy by far more than the normal number of alveoli in the lung lobes; thereafter, normal multiplication of alveoli does not take place and they become enlarged, i.e., emphysematous.

quadrate lobe

frontal lobe,

the largest of five lobes constituting each of the two cerebral hemispheres. It lies beneath the frontal bone; occupies part of the lateral, medial, and inferior surfaces of each hemisphere; and extends posteriorly to the central sulcus and inferiorly to the lateral fissure. It is responsible for voluntary control over most skeletal muscles. The frontal lobe significantly influences personality and is associated with the higher mental activities, such as planning, judgment, emotion, and conceptualization. Compare central lobe, occipital lobe, parietal lobe, temporal lobe.
