2. one of the main divisions of a tooth crown.
azygos lobe (lobe of azygos vein) a small anomalous lobe situated at the apex of the right lung, produced when the azygos vein arches over the upper part of the lung instead of at the hilus and presses deeply into the lung tissue to form a fissure that isolates a medial part of the lung.
caudate lobe a small lobe of the liver between the inferior vena cava on the right and the left lobe.
ear lobe the lower fleshy, noncartilaginous portion of the external ear.
flocculonodular lobe one of the main subdivisions of the cerebellum, located inferiorly, consisting of the paired flocculi, their peduncles, and the nodule of the vermis.

l's of lung the five major subdivisions of the lungs. see accompanying illustration and see lung.

parietal lobe the upper central portion of the gray matter of each cerebral hemisphere, between the frontal lobe and the occipital lobe and above the temporal lobe. It is the receptive area for fine sensory stimuli, and the highest integration and coordination of sensory information is carried on here. Damage to it can produce defects in vision or aphasia.

the small posterior and inferior subdivision of the cerebellar cortex that borders the line of attachment of the choroid roof of the rhomboid fossa, and consists of the left and right flocculus together with the unpaired nodulus (the most posterior of the folia that form the vermis cerebelli). Its major afferent connections come from the vestibular nuclei and directly from the vestibular nerve; it projects largely to the vestibular nuclei, directly and by way of the fastigial nucleus.
