nodulärer

Nodulär is a Swedish adjective meaning having nodules or relating to nodules. It is used across disciplines to describe a morphology characterized by small, rounded protuberances or discrete lumps (nodules) within a tissue, rock, or plant organ.

In medicine and pathology, nodulära lesions are typically solid, elevated lesions that are distinct from flat or superficial changes. They are often described as dome-shaped or rounded and may vary in size. The term is used for various conditions, including dermatological lesions and tumors. A well-known example is nodular melanoma, a form of skin cancer that tends to grow as raised nodules.

In geology and mineralogy, nodulär textures describe rocks in which nodules—concentrations of minerals such as calcium carbonate, silica, or iron minerals—occur embedded within a finer matrix. These nodules can form through precipitation, concretion, or diagenetic processes and may contrast with the surrounding rock in composition or structure.

In botany and agronomy, nodular structures include root nodules on legumes, formed through a symbiosis with nitrogen-fixing bacteria. These nodules enable the plant to convert atmospheric nitrogen into a form usable for growth and are a key feature in studies of plant nutrition and soil fertility. Nodular features can also appear on stems or other plant parts in various species, described as nodular when they present as small swellings or lumps.

The term nodulär serves as a descriptive label in multiple scientific contexts and does not designate a single uniform structure or condition.
