Vascular Lacuna
The vascular lacuna (Latin: ''lacuna vasorum (retroinguinalis)'') is the medial compartment beneath the inguinal ligament. It is separated from the lateral muscular lacuna by the iliopectineal arch.Ross, L.M., Lamperti, E.D. (2006). Thieme: Atlas of Anatomy: 489 It gives passage to the femoral vessels, lymph vessels and lymph nodes. The lacunar ligament can be a site of entrapment for femoral hernias. Anatomy Its boundaries are the iliopectineal arch, the inguinal ligament, the lacunar ligament, and the superior border of the pubis. Contents The structures found in the vascular lacuna, from medial to lateral, are: * Cloquet's node; * Femoral vein; * Femoral artery; and * Femoral branch of the genitofemoral nerve The genitofemoral nerve is a mixed branch of the lumbar plexus derived from anterior rami of lumbar nerves L1–L2.

Inguinal Ligament
The inguinal ligament (), also known as Poupart's ligament or groin ligament, is a band running from the pubic tubercle to the anterior superior iliac spine. It forms the base of the inguinal canal through which an indirect inguinal hernia may develop. Structure The inguinal ligament runs from the anterior superior iliac crest of the ilium to the pubic tubercle of the pubic bone. It is formed by the external abdominal oblique aponeurosis and is continuous with the fascia lata of the thigh. There is some dispute over the attachments. Structures that pass deep to the inguinal ligament include: * Psoas major, iliacus, pectineus * Femoral nerve, artery, and vein * Lateral cutaneous nerve of thigh *Lymphatics Function The ligament serves to contain soft tissues as they course anteriorly from the trunk to the lower extremity. This structure demarcates the superior border of the femoral triangle. It demarcates the inferior border of the inguinal triangle. The midpoint ...

Muscular Lacuna
The muscular lacuna (Latin: ''lacuna musculorum'') is the lateral compartment of the thigh beneath the inguinal ligament. It is separated from the medial vascular lacuna by the iliopectineal arch. It is occupied/traversed by the iliopsoas muscle, and femoral nerve The femoral nerve is a nerve in the thigh that supplies skin on the upper thigh and inner leg, and the muscles that extend the knee. It is the largest branch of the lumbar plexus. Structure The femoral nerve is the major nerve supplying the ant .... The lateral cutaneous nerve of the thigh may pass through the muscular lacuna, or it may pierce the inguinal ligament itself. References Muscular system {{musculoskeletal-stub ...

Iliopectineal Arch
The iliopectineal arch is a thickened band of fused iliac fascia and psoas fascia passing from the posterior aspect of the inguinal ligament anteriorly across the front of the femoral nerve to attach to the iliopubic eminence of the hip bone posteriorly. The iliopectineal arch thus forms a septum which subdivides the space deep to the inguinal ligament into a lateral muscular lacuna and a medial vascular lacuna. When a psoas minor muscle is present, its tendon of insertion blends with the iliopectineal arch It is sometimes transected in treatment of femoral nerve The femoral nerve is a nerve in the thigh that supplies skin on the upper thigh and inner leg, and the muscles that extend the knee.

Lymph Node
A lymph node, or lymph gland, is a kidney-shaped organ of the lymphatic system and the adaptive immune system. A large number of lymph nodes are linked throughout the body by the lymphatic vessels. They are major sites of lymphocytes that include B and T cells. Lymph nodes are important for the proper functioning of the immune system, acting as filters for foreign particles including cancer cells, but have no detoxification function. In the lymphatic system, a lymph node is a secondary lymphoid organ. A lymph node is enclosed in a fibrous capsule and is made up of an outer cortex and an inner medulla. Lymph nodes become inflamed or enlarged in various diseases, which may range from trivial throat infections to life-threatening cancers. The condition of lymph nodes is very important in cancer staging, which decides the treatment to be used and determines the prognosis. Lymphadenopathy refers to glands that are enlarged or swollen. When inflamed or enlarged, lymph nodes can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lacunar Ligament
The lacunar ligament, also named Gimbernat's ligament, is a ligament in the inguinal region. It connects the inguinal ligament to the pectineal ligament, near the point where they both insert on the pubic tubercle. Structure The lacunar ligament is the part of the aponeurosis of the external oblique muscle that is reflected backward and laterally and is attached to the pectineal line of the pubis. It is about 1.25 cm. long, larger in the male than in the female, almost horizontal in direction in the erect posture, and of a triangular form with the base directed laterally. Its ''base'' is concave, thin, and sharp, and forms the medial boundary of the femoral ring. Its ''apex'' corresponds to the pubic tubercle. Its ''posterior margin'' is attached to the pectineal line, and is continuous with the pectineal ligament. Its ''anterior margin'' is attached to the inguinal ligament. Its surfaces are directed upward and downward. Clinical significance The lacunar ligament is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloquet's Node
Inguinal lymph nodes are lymph nodes in the groin. They are situated in the femoral triangle of the inguinal region. They are subdivided into two groups: the superficial inguinal lymph nodes and deep inguinal lymph nodes. Superficial inguinal lymph nodes The superficial inguinal lymph nodes are the inguinal lymph nodes that form a chain immediately inferior to the inguinal ligament. They lie deep to the fascia of Camper that overlies the femoral vessels at the medial aspect of the thigh. They are bounded superiorly by the inguinal ligament in the femoral triangle, laterally by the border of the sartorius muscle, and medially by the adductor longus muscle. There are approximately 10 superficial lymph nodes. They normally measure up to 2 cm in diameter. Last updated: Last updated: Feb 16, 2017 They are divided into three groups: * inferior – inferior of the saphenous opening of the leg, receive drainage from lower legs * superolateral – on the side of the saphenou ...

Femoral Vein
In the human body, the femoral vein is the vein that accompanies the femoral artery in the femoral sheath. It is a deep vein that begins at the adductor hiatus (an opening in the adductor magnus muscle) as the continuation of the popliteal vein. The great saphenous vein (a superficial vein), and the deep femoral vein drain into the femoral vein in the femoral triangle when it becomes known as the common femoral vein. It ends at the inferior margin of the inguinal ligament where it becomes the external iliac vein. Its major tributaries are the deep femoral vein, and the great saphenous vein. The femoral vein contains valves. Structure The femoral vein bears valves which are mostly bicuspid and whose number is variable between individuals and often between left and right leg. Course The femoral vein continues into the thigh as the continuation from the popliteal vein at the back of the knee. It drains blood from the deep thigh muscles and thigh bone. Proximal to th ...

Femoral Artery
The femoral artery is a large artery in the thigh and the main arterial supply to the thigh and leg. The femoral artery gives off the deep femoral artery and descends along the anteromedial part of the thigh in the femoral triangle. It enters and passes through the adductor canal, and becomes the popliteal artery as it passes through the adductor hiatus in the adductor magnus near the junction of the middle and distal thirds of the thigh. The femoral artery proximal to the origin of the deep femoral artery is referred to as the ''common femoral artery'', whereas the femoral artery distal to this origin is referred to as the ''superficial femoral artery''. Structure The femoral artery represents the continuation of the external iliac artery beyond the inguinal ligament underneath which the vessel passes to enter the thigh. The vessel passes under the inguinal ligament just medial of the midpoint of this ligament, midway between the anterior superior iliac spine and ...

Genitofemoral Nerve
The genitofemoral nerve is a mixed branch of the lumbar plexus derived from anterior rami of lumbar nerves L1–L2. It splits into a genital branch and a femoral branch. It provides sensory innervation to the upper anterior thigh, as well as the skin of the anterior scrotum in males and mons pubis in females. It also provides motor innervation to the cremaster muscle (via its genital branch). Structure Origin The genitofemoral nerve is a branch of the lumbar plexus. It is derived from the anterior rami of lumbar nerves L1–L2. It coalesces within the substances of the psoas major muscle. Course It passes downwards, pierces the psoas major and emerges from its anterior surface. The nerve divides into two branches, the genital branch and the lumboinguinal nerve also known as the femoral branch, both of which then continue downwards and medially to the inguinal and femoral canal respectively. Branches Genital branch The genital branch continues downward on the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
