Check out the posture of quadrupeds against that of bipeds, and consider where the weight of (especially abdominal) organs is expressed in the bodies of quadrupeds vs bipeds.

An inguinal hernia is the medical term meaning displacement of the intestines through the inguinal canal. Other relatively common types of hernias are umbilical, ventral, and incisional hernias.

This is probably related to our bipedalism (upright position). Our abdominal organs are subject to gravity and tend to lean more heavily on the membranes that separate the intestines from the reproductive and urinary apparatus. Under certain circumstances (a specially intense effort, some malformation, etc.) the intestines will "fall" to a lower position if there is one (as in this case, which is only possible in males). In a quadruped, the intestines are in a different position and gravity does not have a similar effect. They may develop a hanging belly, but their abdominal organs do not tend to move to the rear.

Both men and women can get hernias the same way, a weak place in the muscles of the wall of a body cavity splits and allows the cavity contents to protrude. Hernias involving the abdominal cavity are common in men and women. They can happen any place in the abdominal wall muscles. They are called ventral hernias. A type more common in men, but also seen in women, occurs in the groin area called the inguinal area on either (or both) sides of the low abdomen and are called inguinal hernias. These frequently show up after a heavy lifting strain and protrude/"rupture". A lump may appear in the area with the pain which is actually a portion of bowel protruding through the muscle opening. In men, inguinal hernias may not show a lump in the inguinal area if the area of weakness is at the bottom and bowel slips into the scrotum and protrudes there as a lump in the scrotum. Other common places in the abdominal cavity wall that can "rupture" are in the area around or near the belly button, which are called umbilical hernias, or at an incision site from a previous surgery called incisional hernias.

What is a Hernia?Hernias occur when a portion of the intestine or abdominal tissue push through a weakened portion of the abdomen wall. A hernia can result from physical strain such as heavy lifting, chronic coughing or constipation. Other causes include obesity and surgery. Some hernias develop at birth, while others appear in adulthood. The six common types of hernias, in order of severity, are inguinal, femoral, umbilical, incisional, epigastric and hiatal. The hernia type determines the treatment and pain site, which may appear with or without symptoms.SymptomsLump groin or abdomenPain in the groin or abdomenNauseaVomitingSwelling or discoloration at the groin sitePain during, or the inability to have a bowel movementPain in the groin or abdomenUrinary problems such as frequent urination, bladder infections and bladder stonesTypes of HerniasInguinal hernias appear when tissue pushes through a fragile area in the groin muscle. Openings in the groin muscle wall generally close after birth. An inguinal hernia occurs when the opening does not close, the muscle wall weakens allowing tissue to protrude and create a bulge. The only treatment for an inguinal hernia is surgery.Femoral hernias occur when the tissue protrudes from the lower abdomen into the upper thigh, right below the groin fold. The femoral hernia location can occur in the same site as an inguinal hernia, which makes this hernia type difficult to diagnose without further testing. Doctors normally find this hernia when a strangulated hernia develops. A strangulated hernia occurs when a trapped portion of the intestine interrupts the blood supply to the tissue. Strangulated hernias are always painful and require emergency surgery. Femoral hernias generally occur in women.Umbilical hernias occur in children and adults around the navel area. In children, these hernias generally heal without medical treatment by the age of one. Hernias that do not close within the first year require surgery. An umbilical hernia may occur in adults due to obesity, pregnancy or excess fluid in the abdomen. These hernias increase in size over time. If left untreated, a strangulated hernia may occur. Babies suffering from an umbilical hernia tend to cry more.Incisional Hernias typically appear after surgery, along a vertical incision. Causes of this hernia include obesity, age, steroid medication use, lung problems or more than one surgery at the same incision site.An epigastric hernia appears between the sternum, known as the breast bone, and the navel. An individual can have more than one of these small-size hernias.A hiatal hernia involves the stomach, not the intestine. This hernia occurs when a portion of the stomach pushes through the diaphragm into the chest. These hernias require medical diagnosis, as they do not normally exhibit symptoms. However, a hiatal hernia can cause heartburn or gastroesophageal reflux disease, known as GERD. Individuals with no symptoms require no treatment. However, if diagnosed with a hiatal hernia, the doctor may prescribe medication or suggest a lifestyle change.While it is important to understand the causes, symptoms and types of hernias, never self-diagnose. Speak with a licensed medical practitioner to obtain an accurate diagnosis and hernia treatment.

As with most medical concerns, only a visit with your physician will appropriately answer this question.Vomiting with an inguinal hernia may be for a number of reasons. First, individuals with inguinal hernias may get the stomach flu (gastroenteritis) like anyone else; this may cause vomiting, although it's not related to the hernia per se.Causes of vomiting related to the inguinal hernia include bowel obstruction (from a loop of bowel getting stuck within the hernia defect), strangulated bowel (when the blood supply to that loop of bowel becomes compromised), perforated bowel, and infarcted (dead) bowel. Other things may cause the nausea and vomiting, but these would be some of the more concerning.If you have an inguinal hernia and experience vomiting that concerns you, please see a physician. Only she can evaluate you properly to assess the source of the vomiting and whether intervention is necessary.

Animals that walk on four legs are called 'quadrupeds'

The other name for the iliac region is INGUINAL

The midpoint of the inguinal ligament and the mid-inguinal point are two different anatomical landmarks in the inguinal region. In order to understand the difference, some simple anatomical knowledge must be clarified.The inguinal ligament stretches from the anterior superior iliac spine (ASIS) to the pubic tubercle. The pubic symphysis lies just medial to the pubic tubercle and is the fibrous joint between the two halves of the pelvis.Running under the inguinal ligament from medial to lateral are: femoral canal (a potential space that contains mainly lymphatics), femoral vein, femoral artery and femoral nerve.The midpoint of the inguinal ligament is half way between the ASIS and the pubic tubercle and is the location of the femoral nerve. This landmark is used in femoral nerve blocks.The mid-inguinal point is half way between the ASIS and the pubic symphysis and is the location of the femoral artery. This landmark is used in palpation of the femoral pulse.In relation to each other, the mid-inguinal point is more medial than the midpoint of the inguinal ligament.

While hernias are a risk factor after any abdominal surgery they are half as likely to occur if the surgery is laparoscopic instead of open incision. There are many other risk factors and complications such as gall stones that occur in 1/3 of patients after this type of surgery., or your doctor are good sources of information.

A hernia is a common ailment caused by the protrusion of an organ, or the tissues surrounding an organ, into a weakened area in the walls or muscles that contain it. While herniated discs of the spine are common and usually treated without surgery, the focus of this article is on the treatment of abdominal hernias, which is by the far the most common location of hernias.Causes of herniasUsually the causes of weakened membranes or muscles in the abdomen are congenital, and hernias tend to run in families. There are other causes, including weakening of the abdominal muscles during pregnancy, rapid weight loss, scars from previous surgeries or other diseases. Inguinal hernias, located just above the groin area, make up about 75 percent of abdominal hernias, with femoral, umbilical, incisional, diaphragmatic and other locations comprising the rest.TreatmentBecause the complications of an untreated abdominal hernia are sometimes severe and can include organ dysfunction and gangrene, it is almost always best to repair an abdominal hernia as soon as possible. The newest treatments involve placing a synthetic mesh material either over the defect in the abdomen, called an anterior repair, or (preferably) under the defect, called a posterior repair. This contrasts with older methods which involved pulling the muscles together under tension and suturing the muscles together. Evidence suggests that these newer methods provide a faster recovery time and significantly fewer complications.Quick recovery timeThis surgery is often performed on an outpatient basis, and patients are commonly able to return to work within a week or two with limitations on their activities. Complications occur in about 10 percent of post-surgical cases but are usually minor and easily addressed.Prepare for your post operative recovery time ahead of time. Make necessary adjustments to your home, and notify your workplace of your expected physical limitations. Things to avoidHernia belts, trusses, trunks and other external devices which reduce the symptoms of the hernia without addressing the underlying cause are not recommended. The exceptions include cases of acute incisional hernias that occur shortly after surgery and cases in which surgery is not possible.Untreated hernias are often very painful and even life threatening if the blood supply to the underlying organ is compromised. At the first sign of a hernia, you should see a doctor and begin the process of recovery.
