Lífeðlisfræðilegra

Lífeðlisfræðilegra is an Icelandic adjective form meaning “physiological,” used to describe phenomena, processes, or properties related to physiology—the study of how living organisms function. The root lífeðlisfræði denotes physiology, combining líf (life) with eðli/fræði (study of). The suffix -legr yields adjectives, and lífeðlisfræðilegur is the masculine nominative singular form; lífeðlisfræðilegra is a declined form used in certain cases, most commonly in genitive and other contexts when modifying a plural noun.

In usage, lífeðlisfræðilegra serves to set apart physiological aspects from structural or anatomical ones (líffræðilegur) or from pathological aspects. It is employed primarily in academic and professional Icelandic, including medicine, biology, psychology, and sports science, to indicate relations to bodily function rather than form or disease.

The term embodies the functional focus of physiology, distinguishing it from related fields such as anatomy (structure) and pathology (dysfunction). It can appear in phrases describing characteristics, processes, or measurements tied to normal bodily operation, such as studies of physiological processes in humans or other organisms.
