Which of the following is the larger of the two oblique abdominal muscles?

The external obliques are indeed the larger of the two oblique abdominal muscles. These muscles are situated on the sides and front of the abdomen and play a crucial role in various movements such as rotation and lateral flexion of the trunk. They originate from the lower ribs and run diagonally downward and inward, inserting into the pelvis and the midline of the abdomen.

In contrast, the internal obliques, while also important for trunk movement and stability, are located beneath the external obliques and are smaller in size. The transverse abdominus, which is another abdominal muscle, is the deepest layer and is more significant for core stability than for the overall size of the muscle. The rectus abdominus, commonly referred to as the "abs," runs vertically along the front of the abdomen and is distinct from the oblique muscles. Therefore, while all these muscles contribute to core strength and stability, the external obliques stand out as the larger oblique muscles.
