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. It is the largest branch of the lumbar plexus. Structure The femoral nerve is the major nerve supplying the ant ... entrapment. Additional images File:Slide2gala.JPG, Iliopectal arch.

Iliac Fascia
The iliac fascia (or Abernethy's fascia) is the fascia overlying the iliacus muscle. Superiorly and laterally, the iliac fascia is attached to the inner aspect of the iliac crest; inferiorly and laterally, it extends into the thigh to unite with the femoral sheath; medially, it attaches to the periosteum of the ilium and iliopubic eminence near the linea terminalis, and blends with the psoas fascia and - over the quadratus lumborum muscle - with the anterior layer of thoracolumbar fascia. The iliac fascia overlies the femoral nerve, and lateral femoral cutaneous nerve. Structure It has the following connections: * ''laterally'', to the whole length of the inner lip of the iliac crest. * ''medially'', to the linea terminalis of the lesser pelvis, where it is continuous with the periosteum. At the iliopectineal eminence it receives the tendon of insertion of the psoas minor, when that muscle exists. Lateral to the femoral vessels it is intimately connected to the poster ...

Psoas Fascia
Psoas (from Greek ψόας) can refer to: * Psoas major muscle * Psoas minor muscle The psoas minor muscle ( or ; from ) is a long, slender skeletal muscle. When present, it is located anterior to the psoas major muscle.Tank (2005), p 93Gray (2008), p 1372 Structure The psoas minor muscle originates from the vertical fascicle ... * Psoas sign {{disambiguation ...

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 ...

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 anterior compartment of the thigh. It is the largest branch of the lumbar plexus, and arises from the dorsal divisions of the ventral rami of the second, third, and fourth lumbar nerves (L2, L3, and L4). The nerve enters Scarpa's triangle by passing beneath the inguinal ligament, just lateral to the femoral artery. In the thigh, the nerve lies in a groove between iliacus muscle and psoas major muscle, outside the femoral sheath, and lateral to the femoral artery. After a short course of about 4 cm in the thigh, the nerve is divided into anterior and posterior divisions, separated by lateral femoral circumflex artery. The branches are shown below: Muscular branches * The nerve to the pectineus muscle arises immediately above the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iliopubic Eminence
Medial to the anterior inferior iliac spine is a broad, shallow groove, over which the iliacus and psoas major muscles pass. This groove is bounded medially by an eminence, the iliopubic eminence (or iliopectineal eminence), which marks the point of union of the ilium and pubis. It constitutes a lateral border of the pelvic inlet The pelvic inlet or superior aperture of the pelvis is a planar surface which defines the boundary between the pelvic cavity and the abdominal cavity (or, according to some authors, between two parts of the pelvic cavity, called lesser pelvis an .... The iliopectineal line is the border of the eminence. The psoas minor, when present, inserts at the pectineal line of the eminence.

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 ...

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. It splits into a genital branch and a femoral branch. It provides sensory innervation to the upper anterior thigh, as well as t ... Refe ...

Psoas Minor Muscle
The psoas minor muscle ( or ; from ) is a long, slender skeletal muscle. When present, it is located anterior to the psoas major muscle.Tank (2005), p 93Gray (2008), p 1372 Structure The psoas minor muscle originates from the vertical fascicles inserted on the last thoracic and first lumbar vertebrae. From there, it passes down onto the medial border of the psoas major, and is inserted to the innominate line and the iliopectineal eminence. Additionally, it attaches to and stretches the deep surface of the iliac fascia and occasionally its lowermost fibers reach the inguinal ligament.Bendavid (2001), p 58 It is posteriolateral to the iliopsoas muscle. Variations occur, however, and the insertion on the iliopubic eminence sometimes radiates into the iliopectineal arch.Platzer (2004), p 234 The psoas minor muscle receives oxygenated blood from the four lumbar arteries (inferior to the subcostal artery) and the lumbar branch of the iliolumbar artery.

Pelvis
The pelvis (: pelves or pelvises) is the lower part of an Anatomy, anatomical Trunk (anatomy), trunk, between the human abdomen, abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also called bony pelvis or pelvic skeleton). The pelvic region of the trunk includes the bony pelvis, the pelvic cavity (the space enclosed by the bony pelvis), the pelvic floor, below the pelvic cavity, and the perineum, below the pelvic floor. The pelvic skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs and ...
