Internal oblique muscle
Internal Oblique Muscle
The Internal Oblique Muscle (pronunciation: in-ter-nal o-blique mus-cle) is a significant part of the human anatomy, specifically within the abdominal muscle group.
Etymology
The term "Internal Oblique Muscle" is derived from the Latin words "obliquus", meaning "slanting", and "internus", meaning "inside". This refers to the muscle's position and orientation within the body.
Anatomy
The Internal Oblique Muscle is located within the abdomen, just beneath the external oblique muscle and above the transverse abdominal muscle. It originates from the lumbar fascia, the anterior two-thirds of the iliac crest, and the lateral half of the inguinal ligament. It inserts into the inferior borders of the 10th through 12th ribs, the linea alba, and the pubic tubercle via the conjoint tendon.
Function
The primary functions of the Internal Oblique Muscle include flexion and rotation of the trunk, as well as providing support to the abdominal wall. It also aids in forced respiration, assists in raising intra-abdominal pressure, and is active in lateral flexion of the spine.
