What does the term "morphology" refer to in the context of tissue categorization?

The term "morphology" in the context of tissue categorization specifically refers to the description of the form and structure of tissues. This encompasses various characteristics such as the size, shape, arrangement, and structure of cells and tissues. Understanding morphology is crucial for pathologists and oncologists as it aids in identifying different tissue types and distinguishing between normal and abnormal (i.e., pathological) tissues. Features observed under a microscope, such as cellular architecture and the organization of tissues, play a significant role in diagnosing conditions, including cancer, as they can indicate the presence of malignancy or other diseases. Evaluating morphology can help determine the appropriate treatment and inform prognosis.

The other options, while related to tissue analysis in some way, do not specifically align with the definition of morphology. The function of tissues and their genetic composition pertain to other biological aspects. Pathological changes indeed account for alterations in tissues, but they describe processes rather than the structural characteristics that morphology focuses on.
