Physical action

Physical action" refers broadly to a process or activity involving physical movement or change, whether in inanimate matter (as described by physical laws) or in biological organisms (often including motor and sensory functions)[3][4]. In biology, physical actions can pertain to mechanisms such as muscle contraction, movement, and sensory perception, typically mediated by various molecular entities (like proteins, receptors, or channels), but the term itself does not specify a particular molecule or therapeutic target[1][2][3]. Thus, "physical action" is a concept, not a discrete, actionable target in biomedical or pharmacological contexts.
