The lacunar ligament, also known as the ligamentum lacunare or ligamentum venosum, is a small, thin ligament located in the liver. It is an important anatomical structure that plays a crucial role in the functioning of the liver and its ability to filter blood and produce important enzymes and hormones.
The lacunar ligament is a long, narrow band of connective tissue that extends from the inferior vena cava (IVC) to the liver. It is located in the superior portion of the liver, just below the diaphragm. The IVC is a large vein that carries deoxygenated blood from the lower half of the body to the right atrium of the heart. The lacunar ligament forms a vital link between the IVC and the liver, allowing blood to flow freely between these two organs.
The lacunar ligament is an important part of the hepatic venous system, which is responsible for draining blood from the liver. It is composed of several smaller veins and tributaries that converge to form the lacunar ligament. These smaller veins and tributaries are called the hepatic veins, which carry oxygenated blood from the liver back to the heart.
The lacunar ligament is also closely associated with the portal vein, which is another important blood vessel in the liver. The portal vein carries blood from the intestines, spleen, and pancreas to the liver, where it is filtered and processed. The lacunar ligament helps to regulate the flow of blood between the portal vein and the hepatic veins, ensuring that the liver receives a steady supply of oxygenated blood while also preventing the build-up of excess pressure.
In addition to its role in the hepatic venous system, the lacunar ligament also plays a crucial role in the production of enzymes and hormones. The liver is responsible for producing a variety of enzymes and hormones that are essential for maintaining homeostasis in the body. These enzymes and hormones are produced by specialized cells called hepatocytes, which are found in the liver. The lacunar ligament helps to ensure that these hepatocytes receive an adequate supply of oxygen and nutrients, which are essential for their proper function.
Overall, the lacunar ligament is a small but essential structure that plays a vital role in the functioning of the liver. It helps to regulate the flow of blood between the IVC and the liver, as well as between the portal vein and the hepatic veins. It also helps to ensure that the hepatocytes receive an adequate supply of oxygen and nutrients, which are essential for the production of enzymes and hormones. Without the lacunar ligament, the liver would be unable to function properly, leading to serious health problems.
Lacunar (Gimbernat's) ligament
Recovery varies for each person and depends on the severity of the stroke. The sacrotuberous ligament also serves as a point of attachment for the most caudal fibers of Sacrotuberous ligament dorsal view Obturator membrane Probably the most confined of all the ligaments of the pelvis is the obturator membrane. Smoking, weight training and lifting heavy objects have also been identified as risk factors for developing hernias. It can be subdivided into a central superior ischiofemoral ligament and medial and lateral ischiofemoral ligaments. Some risk factors, such as aging and family history, are beyond your control, but certain lifestyle behaviors can influence risk, like maintaining a healthy diet, avoiding smoking, and exercising for at least 150 minutes per week. Clinical notes An inguinal hernia is the abnormal protrusion of the peritoneal sac with or without abdominal contents through the abdominal wall in the groin. Surprisingly, it starts out as a muscular structure during early childhood.
Of note, the posterior ligament is a solitary band that travels superomedially from the posterior aspect of the fibular head to the lateral condyle of the tibia. J Clin Anat 2009 22:291—295 4. Those with genetic factors People with a family history of stroke might also have a higher risk for lacunar infarct than other groups. Its base is concave, thin, and sharp, and forms the medial boundary of the apex corresponds to the Its posterior margin is attached to the pectineal line, and is continuous with the anterior margin is attached to the Its surfaces are directed upward and downward. Tears can be partial or complete. The displacement of the tibia away from the femur is used to assess whether or not the ligament is torn.
Inguinal ligament: Attachments, function and relations
Additionally, it has cranial attachments to the calcaneofibular ligament of the lateral ligament of the ankle. The The origination of the ligament forms the suffix, while the insertion forms the prefix i. Note that the pre-auricular surface of the ilium is the area just anterior to the auricular surface, which is the area of articulation between the ilium and the sacrum. Carter was relegated to the position of illustrator by Henry Gray and never saw the royalties that the book could have generated for him. The ligament is made up of two bands that originate from the transverse processes of L5.
Lacunar stroke can be a life-threatening emergency. Collateral ligaments Two of the most commonly known ligaments of the knee are the medial and lateral collateral ligaments. Unlike the lateral epicondyle, the medial epicondyle has attachments to the joint capsule of the knee and by extension, to the medial meniscus. On the other hand, the central component extends from the greater trochanter of the femur to the ischium posteroinferior to the acetabulum. HV Carter was born in Yorkshire in 1831. While it does not integrate with the joint capsule, it blends with the tendon of biceps femoris to form its conjoint tendon. The information we provide is grounded on academic literature and peer-reviewed research.
Essential Clinical Anatomy: Third Edition. There are also a number of smaller ligaments formed from the extension of the medial end of the inguinal ligament. Over time, as the hernia gets larger, positive pressure from the abdominal cavity forces peritoneum into the sac. It then travels across the sciatic notch to complete its connection to the falciform process. Image property of: Artist:. The pubofemoral ligament has several attachments. Image property of: Artist: One of concers when using this technique is the presence of the.
It can be further subdivided on microscopic dissection into the posterolateral, anteromedial and intermediate bundles. Last medically reviewed on January 4, 2022 Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. This was against the technique practiced at the time, which was to cut trought the inguinal ligament. They may also carry out a detailed neurological exam to see if there is any damage to the parts of the brain that control your bodily functions. Subsequently, pain and swelling will develop.
While only the talus and calcaneus articulate posteriorly, the navicular bone also articulates with the two anteriorly. Pubofemoral and iliofemoral ligaments There are two major ligaments toward the anterior aspect of the joint. On the inferior surface, the arc-shaped arcuate pubic ligament also crosses from one pubic ramus to the next. He was the son of Henry Barlow Carter, a well-known artist and it is possible that he honed his natural talents with his father. Heart function tests, such as Early treatment for a lacunar stroke increases your chances of survival and may prevent further damage.

If your symptoms are consistent with stroke and present a medical emergency, immediate diagnostic testing will likely include a The doctor might also request a CT angiography. The joint is supported bilaterally by the lateral collateral ligaments and medial deltoid ligaments of the anterior talofibular ligament extends from the malleolus of the fibula and travels anteromedially toward the talus, just anterior to its point of articulation with the navicular bone. Lacunar ligament is the part of the aponeurosis of the external oblique muscle Length -1. The ligament is a common point for clinicians to test the reflexes at the knee. The ligament is the anterior cruciate, and the injurious force is often valgus in nature.
