- The external oblique is a broad, flat sheet of muscle on either side of the abs. It is most notably involved in spinal rotation and spinal lateral flexion. The external oblique is a broad, flat sheet of muscle on either side of the abs.

Functional anatomy of the core: the abdomen Acting alone, the external oblique can flex the trunk, side bend the torso toward the same side (i.e., the side of the contracting muscle), and rotate the trunk toward the opposite side. The internal oblique originates from the thoracolumbar fascia, the inguinal ligament, and the anterior iliac crest.The internal oblique also functions to provide spine stability, and it flexes and rotates the trunk toward the same side (table 2.4).he external oblique is the most superficial muscle of the three flat abdominal muscles (the external oblique, internal oblique, and transversus abdominis).

Abdominal Oblique Trigger Points: South of the Border Pain The Abdominal Oblique Muscles. Location: The Abdominal Oblique muscle group forms the lateral abdominal wall. The two muscles in this group are the External Oblique and Internal Oblique, with the Internal Oblique lying deep to the External Oblique.Function: The abdominal muscles (or core muscles) function to form the foundation for all gross movements of the body.he abdominal oblique muscles form the lateral wall of the abdomen and function to move the trunk relative to the pelvis.

External oblique Together, the external oblique muscles cover the sides of the abdominal area. The intercostal and subcostal nerves connect the external oblique muscles to the brain. The external obliques on either side not only help rotate the trunk, but they perform a few other vital functions. These muscles help pull the chest, as a whole, downwards, which compresses the abdominal cavity. Although relatively minor in scope, the external oblique muscle also supports the rotation of the spine.

Abdominal Internal Oblique Exercises The rectus abdominis, transverse abdominis, external oblique and the internal oblique make up the abdominal muscles. The internal obliques are located just underneath the external obliques and allow you to bend from the side, as well as twist your torso.

External Abdominal Oblique Muscle External Abdominal Oblique Muscle. The external abdominal obliques are a pair of broad, thin, superficial muscles that lie on the lateral sides of the abdominal region of the body.Contraction of these muscles may result in several different actions, but they are best known for their lateral flexion and rotation of the trunk known as a side bend.he external obliques get their name from their position in the abdomen external to the internal abdominal obliques and from the direction of their fibers, which run obliquely (diagonally) across the sides of the abdomen....

What do my oblique muscles do? Your have external obliques and internal obliques. The external oblique is the largest muscle closest to the surface on your side. Its main job is to pull the chest downwards and compress the abdominal cavity. The internal obliques, on the other hand, have two main jobs. First, it counteracts the diaphragm (the muscle that contracts excessively when you hiccup) so that you can exhale. Second, it allows you to rotate and bend from your trunk.

Axial Muscles: Trunk Muscles Anatomy & Support Trunk Muscles. Believe it or not, when I was in college, I did hundreds of sits-ups every day to get a 'six-pack' of abdominal muscles. These sits-ups, along with other similar exercises, work our oblique (that is, not straight) as well as our rectus (or straight) muscles located in the body wall of our trunk. These oblique and rectus muscles are axial muscles, as they're located in the middle, or the axis, of the body.

Abdominal external oblique muscle The external oblique muscle (of the abdomen) (also external abdominal oblique muscle) is the largest and the most superficial (outermost) of the three flat muscles of the lateral anterior abdomen.n most humans (especially females), the oblique is not visible, due to subcutaneous fat deposits and the small size of the muscle. It arises from eight fleshy digitations, each from the external surfaces and inferior borders of the fifth to twelfth ribs.

Abdominal internal oblique muscle 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.he muscle fibers run from these point superiomedially (up and towards midline) to the muscle's insertions on the inferior borders of the 10th through 12th ribs and the linea alba (abdominal midline seam).

Human Physiology/Print Version Five of the extraocular muscles have their origin in the back of the orbit in a fibrous ring called the annulus of Zinn: the four rectus muscles and the superior oblique muscle. The four rectus muscles attach directly to the front half of the eye (anterior to the eye's equator), and are named after their straight paths.

External oblique External oblique. The external oblique muscle is one of the largest parts of the trunk area. Each side of the body has an external oblique muscle. The external oblique muscle is one of the outermost abdominal muscles, extending from the lower half of the ribs around and down to the pelvis.ts lowest part connects to the the top corner of the pelvis (called the crest of the ilium), the bottom-front of the pelvis (the pubis), and the linea alba, a band of fibers that runs vertically along the inside of the abdominal wall. Together, the external oblique muscles cover the sides of the abdominal area.

External Abdominal Oblique Muscle Muscle fibers in the external obliques run medially and inferiorly from the origins to the insertions across the lateral sides of the abdomen and end just lateral to the rectus abdominis muscles. The location and structure of the external abdominal obliques gives them many different possible actions. Contraction of both external obliques together results in the compression of the abdomen (as in sucking in the gut) or the flexion of the trunk (as in performing a crunch or sit-up).
