👉 Diaphototropism is a concept in human anatomy that describes the ability of certain muscles to move in both directions simultaneously. This movement is known as diaphragmatic contractions, which occur when two opposing muscles in the diaphragm contract at the same time. For example, if one muscle (the oblique diaphragmatic muscle) contracts, while another opposing muscle (the sternocleidomastoid muscle) also contracts, the entire diaphragm will move in both directions
