Study Notes
Abdominal Muscles and Ligaments
- The muscle with fibers that run downward, forward, and medially is not specified by name, but this description is characteristic of certain abdominal muscles.

- The muscle that forms the anterior ½ of the outer lip of the iliac crest is not specified by name, but this is a characteristic of a specific abdominal muscle.
External Oblique Ligament
- The ligament formed by the free edge of the external oblique is not specified by name, but this is a characteristic of a specific ligament in the abdominal region.
Fascial Layers
- The fascia consisting of a fatty superficial layer and a deep fibrous layer is the superficial fascia, which is a type of fascia found in the abdominal region.
