-
Thoracolumbar fascia, lateral inguinal ligament, anterior iliac crest
-
Iliac crest
Correct Answer
A. Thoracolumbar fascia, lateral inguinal ligament, anterior iliac crestExplanation
The internal abdominal oblique muscle originates from the thoracolumbar fascia, the lateral inguinal ligament, and the anterior iliac crest. These structures provide attachment points for the muscle, allowing it to function in the movements and support of the abdomen. The thoracolumbar fascia is a strong connective tissue that spans the lower back and provides stability to the trunk. The lateral inguinal ligament is located in the groin area and helps to support the abdominal wall. The anterior iliac crest is the front portion of the hip bone and serves as another attachment point for the muscle.Rate this question:

What is NOT the action of the external abdominal oblique?
-
Medial flex side to side
-
Compresses abdominal viscera
-
Trunk flexes
-
Same shoulder to opposite hip
Correct Answer
A. Medial flex side to sideExplanation
The external abdominal oblique does not medially flex side to side. This muscle is responsible for compressing the abdominal viscera, flexing the trunk, and rotating the same shoulder to the opposite hip. Medial flexion side to side would involve bending the trunk towards the midline, which is not a function of the external abdominal oblique.Rate this question:

-
External surface ribs 5-12
Correct Answer
A. Rectus sheath inguinal ligament anterior iliac crestExplanation
The correct answer is "rectus sheath, inguinal ligament, anterior iliac crest". The external abdominal oblique muscle inserts into the rectus sheath, which is a layer of connective tissue covering the rectus abdominis muscle. It also inserts into the inguinal ligament, which is a band of connective tissue that runs from the anterior superior iliac spine to the pubic tubercle. Additionally, it inserts into the anterior iliac crest, which is the upper curved border of the ilium bone in the pelvis. These insertions allow the external abdominal oblique muscle to contribute to the movement and stability of the trunk and pelvis.Rate this question:
