What are the boundaries of the abdominal wall?
The abdominal wall surrounds the abdominal cavity, providing it with flexible coverage and protecting the internal organs from damage. It is bounded superiorly by the xiphoid process and costal margins, posteriorly by the vertebral column and inferiorly by the pelvic bones and inguinal ligament.
What are the borders of Hesselbach’s triangle?
The Hesselbach triangle is located in the anterior abdominal wall bilaterally (on both the right and left sides) and has three major boundaries: the medial boundary consisting of the rectus abdominis muscle; the lateral boundary consisting of the inferior epigastric vessels, which supply the anterior abdominal wall …
What is an athletic Pubalgia?
Sports Hernia (Athletic Pubalgia) A sports hernia is a painful, soft tissue injury that occurs in the groin area. It most often occurs during sports that require sudden changes of direction or intense twisting movements.
What are the borders of the inguinal canal?
It is found within the aponeurosis of the external oblique, immediately above the pubic crest, 1 centimeter above and superolateral to the pubic tubercle. It has the following boundaries—medial crura by pubic crest, lateral crura by pubic tubercle and inferiorly by inguinal ligament.
What are the layers of the abdominal cavity?
There are nine layers to the abdominal wall: skin, subcutaneous tissue, superficial fascia, external oblique muscle, internal oblique muscle, transversus abdominis muscle, transversalis fascia, preperitoneal adipose and areolar tissue, and peritoneum.
What is the anterior abdominal wall?
The anterior abdominal wall forms the anterior limit of the abdominal viscera and is defined superiorly by the xiphoid process of the sternum and costal cartilages and inferiorly by the iliac crest and pubic bones of the pelvis.
What is the fascia Transversalis?
The transversalis fascia is a thin layer of connective tissue lining most of the abdominal cavity between the posterior surface of the transversus abdominis and superficial to the extraperitoneal fat and peritoneum.
What is lateral umbilical ligament?
The lateral umbilical folds are bilateral raised ridges of parietal peritoneum in the deep aspect of the anterior abdominal wall overlying the inferior epigastric vessels. The paired folds originate medial to the deep inguinal ring and end at the arcuate line on the posterior aspect of the anterior abdominal wall.
Where is the groin on a woman?
Your groin is the area of your hip located between your stomach and your thigh. It is where your abdomen stops and your legs start. If you are a woman with pain in your groin on the right side, the discomfort could be an indication of a number of potential problems.
What is a groin?
The groin is the area in the body where the upper thighs meet the lowest part of the abdomen. Normally, the abdomen and groin are kept separate by a wall of muscle and tissue. The only openings in the wall are small tunnels called the inguinal and femoral canals.
What causes hernia?
What Causes Hernias? Ultimately, all hernias are caused by a combination of pressure and an opening or weakness of muscle or fascia; the pressure pushes an organ or tissue through the opening or weak spot. Sometimes the muscle weakness is present at birth; more often, it occurs later in life.
What is abdominal fascia?
Abdominal fascia refers to the various types of fascia found in the abdominal region. Fascia is a sheet of connective tissue that is found beneath the skin that attaches, stabilizes, encloses, and separates muscles and other internal organs. Everyone has fascia, as it is part of how the human body is composed.
What are the borders of the abdominal cavity made of?
The borders of the abdominal cavity are comprised of the posterior peritoneal surface, the anterior abdominal wall, the inferior pelvic inlet, and the superior thoracic diaphragm. The abdomen functions to house the digestive system and provides muscles essential for posture, balance, and breathing.
What is the organization of the abdominal cavity?
A central gut tube (gastrointestinal system) which is suspended from the posterior abdominal wall and also somewhat from the anterior abdominal wall with thin sheets of tissue is the typical organization of the abdominal cavity.
What are the three spaces within the abdominal cavity?
Within the cavity are the lesser and greater omentum, the mesenteries, the ligaments, and multiple fluid spaces (lesser sac, perihepatic space, and subphrenic space). The peritoneum is a smooth membrane that lines the entire abdominal cavity and is reflected over the contained organs.
How does the peritoneum support the abdominal cavity?
The peritoneum, by connecting the visceral with the parietal portions, assists in the support and fixation of the abdominal organs. The diverse attachments of the peritoneum divide the abdominal cavity into several compartments. Some of the viscera are attached to the abdominal walls by broad areas of the peritoneum, as is the pancreas.
