What are the actions of the Quadratus Lumborum?
- A.
Compresses abdominal viscera medial flexes trunk to same side
- B.
Extension of vertebrae column
- C.
Fixes 12th rib during respiration and lateral flexes to same side
- D.
Rotation to same side and extension of vertebrae column
Correct Answer
C. Fixes 12th rib during respiration and lateral flexes to same sideExplanation
The Quadratus Lumborum is a muscle located in the lower back. It has multiple actions, including fixing the 12th rib during respiration and laterally flexing the trunk to the same side. This means that when the muscle contracts, it helps to stabilize the 12th rib during breathing and also assists in bending the trunk sideways towards the same side.Rate this question:

What are the actions of the internal abdominal oblique?
- A.
Same shoulder to opposite hip, flex trunk
- B.
Compresses and supports abdominal viscera
- C.
Supports abdominal viscera, flex trunk, same shoulder to same hip
- D.
Lateral flex side to side and compresses abdominal viscera
Correct Answer
C. Supports abdominal viscera, flex trunk, same shoulder to same hipExplanation
The internal abdominal oblique is a muscle located in the abdominal region. Its main actions include supporting the abdominal viscera (organs), flexing the trunk (bending the torso forward), and laterally flexing the torso from the same shoulder to the same hip. These actions help in maintaining posture, providing stability to the abdominal region, and assisting in movements such as bending forward and twisting the torso.Rate this question:

What are the insertions of the Rectus abdominis?
- A.
Xiphoid process inferior ribs (costal cartilages 5-7)
- B.
Symphysis pubis pubic crest
- C.
Rectus sheath inguinal ligament anterior iliac crest
- D.
Linea alba pubis xiphoid process
Correct Answer
A. Xiphoid process inferior ribs (costal cartilages 5-7)Explanation
The correct answer is xiphoid process inferior ribs (costal cartilages 5-7). The rectus abdominis is a long, flat muscle that runs vertically along the front of the abdomen. It originates from the xiphoid process (a small bone at the bottom of the sternum) and inserts into the inferior ribs, specifically the costal cartilages of ribs 5-7. This muscle is responsible for flexing the trunk, compressing the abdominal contents, and stabilizing the pelvis and spine.Rate this question:

Where do the fibers of the internal abdominal oblique run?
- A.
The fibers run in fingers in pocket's direction
- B.
The fibers run transverse
- C.
The fibers run in thirty degree angle
- D.
The fibers run at right angle to external abdominal oblique
Correct Answer
D. The fibers run at right angle to external abdominal obliqueExplanation
The fibers of the internal abdominal oblique run at a right angle to the external abdominal oblique. This means that they run perpendicular to the fibers of the external abdominal oblique, which is the muscle located on the outermost layer of the abdominal wall. This arrangement of fibers allows for the muscles to work together in providing support and stability to the abdominal region.Rate this question:

- D.
Rectus sheath inguinal ligament anterior iliac crest
Correct Answer
C. Iliac crest and lower lumbar vertebraeExplanation
The quadratus lumborum originates from the iliac crest and lower lumbar vertebrae. This muscle is located in the lower back and plays a role in stabilizing the spine and pelvis. Its attachment to the iliac crest and lumbar vertebrae allows it to exert force and control movement in this area.Rate this question:

What are the actions of the rectus abdominis?
- A.
Lateral flex side to side, flexes trunk, and compresses abdominal fascia
- B.
Supports abdominal fascia trunk flexion
- C.
Compresses abdominal fascia flex trunk
- D.
Same shoulder to same hip trunk flexion compresses abdominal fascia
Correct Answer
C. Compresses abdominal fascia flex trunkExplanation
The rectus abdominis is a muscle located in the front of the abdomen. It is responsible for flexing the trunk, meaning it helps to bend the spine forward. Additionally, it compresses the abdominal fascia, which is a layer of connective tissue that surrounds the abdominal muscles. This compression helps to stabilize the core and support the abdominal organs.Rate this question:

- C.
Twelfth rib upper lumbar vertebrae
- D.
Ribs 10-12, rectus sheath
Correct Answer
A. Thoracolumbar fascia, costal cartilages 7-12, iliac crest, inguinal ligamentExplanation
The transversus abdominis muscle originates from the thoracolumbar fascia, costal cartilages 7-12, iliac crest, and inguinal ligament.Rate this question:

What are the origins of the internal abdominal oblique?
- A.
Thoracolumbar fascia, inguinal ligament
- B.
Thoracolumbar fascia, lateral inguinal ligament, posterior iliac crest
- C.
Thoracolumbar fascia, lateral inguinal ligament, anterior iliac crest
- D.
Iliac crest
Correct Answer
C. 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?
- A.
Medial flex side to side
- B.
Compresses abdominal viscera
- C.
Trunk flexes
- D.
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:

- B.
Rectus sheath inguinal ligament anterior iliac crest
- C.
Linea alba, pubis, xiphoid process
- D.
External surface ribs 5-12
Correct Answer
B. 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:

What are the actions of the transversus abdominis?
- A.
Supports abdominal oblique
- B.
Flexes trunk
- C.
Same shoulder to same hip
- D.
Compresses and supports abdominal oblique
Correct Answer
D. Compresses and supports abdominal obliqueExplanation
The transversus abdominis is a deep muscle in the abdomen that plays a crucial role in stabilizing the core. It functions by compressing and supporting the abdominal oblique muscles. This action helps to maintain proper posture, protect the spine, and provide stability during movements such as lifting or twisting.Rate this question:

What is the insertion of the internal abdominal oblique?
- A.
Ribs 10-12 rectus sheath
- B.
Anterior iliac crest lateral inguinal ligament
- C.
Pubic crest xiphoid process
- D.
Thoracolumbar fascia costal cartilages 7-12
Correct Answer
A. Ribs 10-12 rectus sheathExplanation
The internal abdominal oblique muscle inserts into the ribs 10-12 and the rectus sheath. This means that the muscle attaches to these structures, providing support and stability to the abdominal wall. The ribs 10-12 are the lower ribs, and the rectus sheath is a layer of connective tissue that covers the rectus abdominis muscle. The insertion of the internal abdominal oblique into these structures allows it to contribute to the movements and functions of the abdominal wall.Rate this question:
