internal oblique opposes the external oblique
A Right Anterior Oblique position for the sternum is preferred over a Left Anterior Oblique because it better visualizes the sternum without superimposing anatomical structures. This positioning also minimizes radiation exposure to critical organs such as the heart.
The inguinal ligament runs deep to the external oblique muscle.
The external abdominal obliques are on both sides of your torso. They run diagonally from external surfaces of ribs 5-12 (origin) to the anterior illiac crest and abdominal aponeurosis (insertion).

run at an oblique angle to vertical direction of the spine.
The anterior iliac crest serves as the origin for several muscles, primarily the tensor fasciae latae and part of the sartorius muscle. Additionally, it provides attachment for the external oblique muscle and plays a role in the origin of the internal oblique and transversus abdominis muscles. These muscles contribute to various movements of the hip and trunk.

From superficial to deep the mucsles are: external oblique internal oblique transversus abdominis
Those lines are usually referred to as "obliques" or "abdominal oblique muscles." They are located on the sides of the abdomen and help with twisting and bending movements. Strengthening these muscles can help enhance definition and create a more sculpted appearance.
The external oblique muscles form the external lateral walls of the abdomen. These muscles run diagonally down and towards the midline of the body, aiding in movements like trunk flexion and rotation.
