👉 In anatomy, a "pretibial" refers to a region of the abdomen that is located between the left and right lower abdominal muscles. It includes the abdominal wall, including the internal organs (like the liver and gallbladder), and also extends into the pelvic area. The term "pretibial" is often used in conjunction with other terms such as "piligran," which refers to a soft, sticky substance that can be found on the surface of the bladder.
