Nonlobular

The term 'nonlobular' describes something that lacks the characteristic lobes or subdivisions typically found in a lobular structure. Lobes are rounded, protruding segments often seen in organs like the liver, lungs, and brain. Therefore, 'nonlobular' signifies a structure that is not divided into distinct lobes, presenting a more uniform or undivided appearance. This can apply to various biological structures, tissue arrangements, or even geological formations. Essentially, it indicates the absence of the morphological feature of lobulation. Understanding this term is crucial in fields like anatomy, pathology, and geology for accurately describing and interpreting observed structures.

Nonlobular meaning with examples

• The pathologist noted the tumor's nonlobular growth pattern, observing a homogenous mass lacking the typical subdivided structure of a healthy liver. This uniform appearance suggested a more aggressive form of cancer, necessitating further investigation to determine its stage and nature.
• Microscopic analysis revealed the lung tissue exhibited a nonlobular architecture, as the alveoli, normally grouped into lobules, were disrupted by the formation of scar tissue. This altered structure resulted in reduced oxygen exchange capacity in the lungs, contributing to the patient's respiratory difficulties.
• In contrast to the brain's clearly defined lobular organization, the observed lesion presented a nonlobular structure, spreading in an irregular fashion across multiple areas. The lack of clear boundaries posed a challenge for surgical planning, necessitating careful consideration for successful resection.
• Geologists studying the ancient rock formations determined a nonlobular structure in the sedimentary deposits, suggesting the absence of the usual layering effects. The data informed the scientists that environmental factors during deposition were likely uniform and consistent, which helped explain its formation.
• Examining the newly discovered organ, the anatomists found its overall nonlobular presentation, being a solid, seamless entity instead of the anticipated lobulated design. The absence of lobules has had significant impacts on how it functions in comparison to analogous organs in other species, requiring its own classification.
