		Its fibers run perpendicular to the external oblique muscle, beginning in the thoracolumbar fascia of the lower back, the anterior 2/3 of the iliac crest (upper part of hip bone) and the lateral half of the inguinal ligament.
		The internal oblique is innervated by the lower intercostal nerves, as well as the iliohypogastric nerve and the ilioinguinal nerve.
		For example, the right internal oblique and the left external oblique contract as the torso flexes and rotates to bring the left shoulder towards the right hip.

		The abdominals are composed of four muscle groups: the rectus abdominis, the external and internal obliques and the transversus abdominis.
		Both the external and internal oblique muscles are involved in flexing the rib cage and the hip bone together, side-bending the spine and rotating the spine.
		Although most people think the oblique muscles are only frontal muscles, it is important to note that their fan-like fibers extend all the way around the sides to the lower back, much the way a corset fits.

		It arises, as fleshy fibers, from the lateral third of the inguinal ligament, from the anterior three-fourths of the inner lip of the iliac crest, from the inner surfaces of the cartilages of the lower six ribs, interdigitating with the diaphragm, and from the lumbodorsal fascia.
		The muscle ends in front in a broad aponeurosis, the lower fibers of which curve downward and medialward, and are inserted, together with those of the internal oblique muscle, into the crest of the pubis and pectineal line, forming the inguinal aponeurotic falx.

	Nikon MicroscopyU: Stereomicroscopy
		Oblique Illumination - Specimens that are nearly transparent and colorless may be almost invisible when viewed in the stereomicroscope using traditional transmitted (diascopic) brightfield illumination techniques.
		However, if the illumination is directed so that it originates from a single azimuth and strikes the specimen from an oblique angle, details in the specimen may be revealed with much greater contrast and visual clarity than when the light is allowed to pass directly through specimen features along the optical axis of the microscope.
		Oblique Coherent Contrast Illumination - Transparent specimens, which are almost invisible when viewed in the stereomicroscope using traditional brightfield illumination techniques, often assume a pseudo three-dimensional appearance with stark contrast when viewed in oblique illumination.

		The main function of the rectus abdominus is to move the body between the ribcage and the pelvis.

		The external obliques run from the external surfaces of the last 8 ribs to the anterior portion of the iliac crest and the aponeurosis of the anterior abdominal wall (Figure 2A).
		Whereas the internal obliques are an ipsilateral rotator of the trunk while the pelvis is fixed, the external obliques act as a contralateral rotator of the trunk while the pelvis is fixed.
		Whereas many oblique and rotational exercises are performed by rotating the upper torso, this variation on the Russian Twist rotates the lower torso.

	BioMed Central \| Abstract \| Trunk muscle activity in healthy subjects during bridging stabilization exercises
		During all bridging exercises, the ratio of the internal oblique to the rectus abdominis was very high due to minimal relative activity of the rectus abdominis.
		However, during the unilateral bridging exercise, the ipsilateral internal/external abdominal oblique activity ratio was 2.79 as a consequence of the significant higher relative activity of the internal oblique compared to the external oblique.
		Both the minimal relative activity of the rectus abdominis and the high internal oblique to the rectus abdominis activity ratio reported in the present study are in accordance with results of other trunk stabilization exercises.

		The internal oblique and erector spinae were not influenced.
		It may be argued that the increase in activation levels of the external oblique and the rectus abominis during prone bridging appear to be caused by decreases in surface stability and not different biomechanical demands due to the body's position relative to gravity.
		Figure 6 shows the average activity in the internal oblique muscle during prone bridging on and off a Swiss ball for one repetition from each subject.

		The muscle lies just below the internal oblique and spans the area from the pelvis to the six lower ribs and the lumbar region of the spine, where it connects to the lumbar fascia.
		The internal oblique is a small, thin, deep muscle of the abdomen.
		The external oblique is a large, thin sheet of overlapping muscle that runs along the side of the torso and partly on the front from the lower ribs to the rectus, the pubis bone, and the iliac crest of the hip.
