Questions and Answers
- 1.
Pectin pubis is the same as the pectineal line or the line of the pubic ramus.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because both "pectin pubis" and "pectineal line" refer to the same anatomical structure. The pectin pubis is a ridge on the superior ramus of the pubis bone, while the pectineal line is the same ridge referred to by its anatomical name. Therefore, they are interchangeable terms for the same structure.Rate this question:

If the xiphoid process breaks off it will hit the _____.
Correct Answer
liverExplanation
If the xiphoid process breaks off, it can hit the liver. The xiphoid process is a small, cartilaginous extension at the lower end of the sternum. In rare cases, it can become fractured or break off due to trauma or injury. If this happens, the broken piece of the xiphoid process can potentially cause damage to nearby organs, including the liver. The liver is located just below the xiphoid process, and if the broken piece hits it, it can lead to pain, discomfort, and potentially more severe complications.Rate this question:

- 5.
The inguinal ligament is not a ligament.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because the inguinal ligament is not actually a ligament. It is a fibrous band that runs from the anterior superior iliac spine to the pubic tubercle. Despite its name, it does not connect bones and is not involved in joint stability. Instead, it serves as a landmark in the groin region and helps to define the boundaries of the inguinal canal.Rate this question:

Where does rectus abdominus not have an attachment
- A.
Xiphoid process
- B.
Iliac crest
- C.
Pubic symphysis
- D.
Lower ribs
Correct Answer
B. Iliac crestExplanation
The rectus abdominis is a paired muscle that runs vertically along the anterior abdominal wall. It is responsible for flexing the trunk and compressing the abdominal contents. The muscle has several attachments, including the xiphoid process, pubic symphysis, and lower ribs. However, it does not have an attachment to the iliac crest, which is the curved ridge of bone that forms the upper border of the hip bone.Rate this question:

Transversus Abdominus inserts on the linea alba, pubic crest, and pectineal line
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The transversus abdominus muscle is a deep muscle of the abdomen that runs horizontally. It originates from the lower ribs and inserts on the linea alba, pubic crest, and pectineal line. This muscle plays a key role in stabilizing the core and supporting the abdominal organs. Therefore, the statement that the transversus abdominus inserts on the linea alba, pubic crest, and pectineal line is true.Rate this question:
-
- 8.
_____ _____ divides the rectus abdominus into two muscles.
Correct Answer
linea albaExplanation
The linea alba is a fibrous band that runs vertically down the midline of the abdomen, dividing the rectus abdominis muscles into two halves. It acts as a central attachment point for the abdominal muscles and provides structural support to the abdominal wall.Rate this question:
- 9.
If you contract all abdominal muscles at the same time you get trunk ______.
Correct Answer
flexionExplanation
When you contract all abdominal muscles at the same time, it causes the trunk to flex. Flexion refers to the movement that decreases the angle between the trunk and the thighs, bending the trunk forward. Contraction of the abdominal muscles helps in flexing the trunk by pulling the ribcage and pelvis closer together, resulting in a forward bending motion.Rate this question:

Aponeurosis means flat tendon
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Aponeurosis refers to a sheet or layer of flat, fibrous tissue that connects muscles to other structures, such as bones or other muscles. It is similar in function to a tendon, but instead of being a cylindrical structure, it is flat and broad. Therefore, the statement that aponeurosis means flat tendon is true.Rate this question:

- B.
Rectus Abdominus
- C.
Internal Oblique
- D.
Transverse Abdominus
Correct Answer
A. External ObliqueExplanation
The external oblique muscle's aponeurosis always goes in front to form the rectus sheath. The rectus sheath is a fibrous sheath that surrounds the rectus abdominis muscle, which is located in the anterior abdominal wall. The external oblique muscle is one of the muscles that make up the abdominal wall, and its aponeurosis contributes to the formation of the rectus sheath.Rate this question:

T12 is always called subcostal from when it exits the spinal cord to when in innervates the abdominal muscles.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
T12 is always called subcostal because it refers to the 12th thoracic spinal nerve, which exits the spinal cord and innervates the abdominal muscles. The term "subcostal" indicates that the nerve is located below the ribs, which is the case for T12. Therefore, it is correct to say that T12 is always called subcostal throughout its course.Rate this question:

The external iliac artery divides into the ________ ______ _______ and the _______ _______.
Correct Answer
deep circumflex iliac, inferior epigastricExplanation
The external iliac artery is a major blood vessel in the body that supplies blood to the lower limbs. It divides into two branches: the deep circumflex iliac artery and the inferior epigastric artery. The deep circumflex iliac artery runs along the iliac crest and supplies blood to the muscles and skin in that area. The inferior epigastric artery runs superiorly towards the abdomen and supplies blood to the lower abdominal wall.Rate this question:
- 21.
For every artery there is a vein counterpart (minus a few exceptions).
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This statement is true because in the circulatory system, arteries and veins are paired structures that work together to transport blood throughout the body. Arteries carry oxygenated blood away from the heart to the tissues, while veins carry deoxygenated blood back to the heart. While there are a few exceptions, such as the pulmonary artery and vein, most arteries have a corresponding vein that serves the same area of the body.Rate this question:
