EXTERNAL OBLIQUE Meaning and
Definition
-
The external oblique refers to a pair of flat, broad muscles located on the outermost sides of the abdomen. It is one of the four main muscles that make up the abdominal wall. The external oblique muscles are arranged diagonally, running from the lower ribs to the pelvis, forming a V-shape as they cover the front and sides of the torso.
These muscles are classified as skeletal muscles, meaning they are under voluntary control and responsible for various movements, particularly those involving the rotation and flexion of the trunk. The external oblique muscles are primarily involved in bending the trunk forward, rotating the trunk to the opposite side, and compressing the abdominal contents.
Externally, these muscles are visibly outlined by a series of fibrous lines known as the linea semilunaris. Along the lower margin of the external oblique, a broad aponeurosis is formed which joins with the aponeuroses of other abdominal muscles, forming the rectus sheath. This sheath encloses the rectus abdominis muscle, adding strength and stability to the abdominal wall.
In addition to their role in trunk movement, the external oblique muscles also play a vital role in protecting the internal organs of the abdominal cavity, promoting posture, and assisting in the process of respiration. Exercising and strengthening the external oblique muscles can contribute to overall core strength and stability.

Etymology of EXTERNAL OBLIQUE
The term "external oblique" has a Latin origin. It is derived from two Latin words:
1. External: The word "external" comes from the Latin word "externus", which means "outside" or "outer". It is derived from the combination of "ex" (meaning "out") and "ternus" (meaning "threefold").
2. Oblique: The word "oblique" is derived from the Latin word "obliquus", which means "slanting" or "inclined". It is believed to have originated from the Latin verb "obliquare", meaning "to turn aslant".
When combined, "external oblique" refers to a muscle in the abdominal region that is situated on the outer side and at an inclined angle.
