Anatomy femoral nerve artery and vein
Anatomy femoral nerve artery and vein-The femoral triangle is a triangular intermuscular space in the anterior thigh through which pass major neurovascular structures (femoral artery, femoral vein, femoral nerve) Additional noteworthy anatomic regions in the thigh include the femoral canal , femoral The femoral branch of the genitofemoral nerve is also lateral to the upper part of the femoral artery, within the femoral sheath, but lower down it passes to the front of the artery • 6 The profunda femoris artery a branch of the femoral artery itself, and its companion vein, lie behind the upper part of the femoral artery, where it lies on the pectineus – Lower down,Anatomy_of_femoral
The femoral artery is a large vessel that provides oxygenated blood to lower extremity structures and in part to the anterior abdominal wall The common femoral artery arises as a continuation of the external iliac artery after it passes under the inguinal ligament The femoral artery, vein, and nerve all exist in the anterior region of the thigh known as the femoral triangle,Results In all 11 cadavers, the retractor tip was medial to the femoral nerve The mean distance from retractor tip to femoral artery and vein was 59 mm (SD = 55, range 0) and 126 mm (SD 07, range 035), respectivelyThe saphenous nerve (also long saphenous nerve, internal saphenous nerve, latin nervus saphenus) is a large cutaneous branch of the femoral nerveThe saphenous nerve contains only sensory fibers The saphenous nerve runs posterior to the sartorius, enters the adductor canal and pierces the anterior wall of the channelAfter emerging from the adductor canal, the saphenous nerve
Femoral artery – Anatomy MCQ All are true regarding femoral artery except?The femoral triangle, where the femoral artery and vein are subcutaneous, represents a site where the pulse is easily taken, where arterial blood can be sampled, and where the arterial tree can be cannulated for experimental or special diagnostic procedures After arising from the lumbar plexus, the femoral nerve travels inferiorly through the psoas major muscle of the posterior abdominal wall It supplies branches to the iliacus and pectineus muscles prior to entering the thigh The femoral nerve then passes underneath the inguinal ligament to enter the femoral triangle Within this triangle, the nerve is located lateral to the femoral vessels (unlike the nerve, the femoral artery and vein
Femoral nerve – innervates the anterior compartment of the thigh, and provides sensory branches for the leg and foot Femoral artery – responsible for the majority of the arterial supply to the lower limb Femoral vein – the great saphenous vein drains into the femoral vein within the triangle The vein is posterior to the femoral artery in the apex and medial to it at the base of the Femoral Triangle It gets the great saphenous vein and profunda femoris vein and veins corresponding to the superficial branches of femoral artery Femoral Nerve The femoral nerve is located lateral to the femoral artery, outside the femoral sheath, in FEMORAL NERVE • The femoral nerve is located lateral to the femoral artery, outside the femoral sheath, in the groove between the iliacus and the psoas major • About 25 cm below the inguinal ligament it divides into anterior and posterior sections which enclose lateral circumflex femoral artery between them
The femoral sheath encloses the femoral artery and vein, and the nerve lies outside the sheath The femoral canal is a space within the femoral sheath and medial to the femoral veinA Leaves the femoral triangle by passing through the adductor canal B Femoral nerve is lateral to the upper part of the femoral artery in the femoral triangle C Femoral branch of genitofemoral nerve is lateral to the upper part of femoral artery within the The roof is composed of skin, superficial fascia, and deep fascia The important contents, from lateral to medial, are the femoral nerve, femoral artery, femoral vein, and the deep inguinal lymph nodes The femoral artery gives off the superficial epigastric artery, superficial and deep pudendal arteries, and the deep artery of the thigh

Within the triangle, identify the femoral nerve, artery and vein, and note their relationships to one another from lateral to medial Observe the termination of the greater saphenous vein Observe the femoral sheath and its compartments Identify the femoral canalThe femoral artery and vein are accessible within the femoral triangle, which is defined by the inguinal ligament superiorly, the adductor longus muscle medially, and the sartorius muscle laterally The inguinal ligament is defined as a line drawn between the symphysis pubis and the anterior superior iliac spineThe femoral vein is commonly used for intravenous infusions in infants and in patients with peripheral circulatory failure profunda femoris vein it is formed in lower part of thigh by union of perforating veins It runs close to the front of profunda femoris artery
The femoral pulse is palpable at this midinguinal point NAVEL is a mnemonic for remembering the neurovascular structures that travel deep to the inguinal ligament into the femoral triangle N = femoral nerve A = femoral artery V = femoral vein EL = empty space (femoral canal) and lymphatics The deep femoral artery arises in the femoral triangle This artery crosses the femoral nerve and femoral vein in such a way as to form a delta shape near the groin region This portion is known as the femoral triangle or Scarpa's triangle3) Nerve to pectineus (note deep to fascia iliaca) Femoral sheath (inferior projection of transversalis fascia anteriorly and iliac fascia posteriorly) 1) Lateral compartment common femoral artery and genitofemoral nerve 2) Intermediate compartment femoral vein 3) Medial compartment = femoral canal lymph node and lymphatics Landmarks
Femoral nerve damage The femoral triangle is formed by the lateral border of adductor longus, the medial border of sartorius and the inguinal ligament (with pectineus and illiopsoas forming the floor) It contains, from lateral to medial, the femoral nerve, artery and veinArteries and Nerves of Thigh Anterior Views Anatomy Anterior superior iliac spine, Inguinal ligament, Iliopsoas muscle, Superficial circumflex iliac vessels, Superficial epigastric vessels, Superficial dissections, Tensor fasciae latae muscle (retracted), Lateral femoral cutaneous nerve (cut), Sartorius muscle (cut), Gluteus minimus and medius muscles, Iliopsoas muscle, Femoral nerve, arteryThe femoral nerve lies outside the femoral sheath A way of remembering the contents of the femoral triangle is the mnemonic NAVY – nerve, artery, vein yfronts (as in briefs or pants, whatever, underwear for men) Nerve, artery, vein from lateral to medial And you've also got this branch of the femoral artery, the profunda femoris If I
Branches from the femoral nerve to mm tensor fasciae latae and adductor longus have been reported A branch was also found passing behind the femoral artery and vein, joining an accessory obturator nerve, and supplying a part of the obturator muscle The portion of the nerve arising from L4 may run a separate courseThe femoral nerve travels posterior to the inguinal ligament within the muscular lacuna The muscular lacuna also contains the iliopsoas muscle NAVEL is a mnemonic for remembering the neurovascular structures that travel deep to the inguinal ligament into the femoral triangle N = femoral nerve A = femoral artery V = femoral vein Within the femoral triangle, the femoral artery is located deep to the Skin Superficial fascia Superficial inguinal lymph nodes Fascia lata Superficial circumflex iliac vein Femoral branch of the genitofemoral nerve
The femoral vein may remain on the medial side of the artery throughout its course in the thigh, or it may be doubled, especially in the adductor canal There is often a plexiform arrangement around the artery in this situation Femoral Vein Anatomy continuation of the popliteal vein lies in the intermediate compartment of the femoral sheath accompanies the femoral artery in the femoral triangle at the inguinal ligament it becomes the external iliac veinModel At first, the femoral nerve lies in the groove between the psoas major and iliacus, further, it leaves the pelvic cavity via the muscular lacuna Then the femoral nerve descends along the medial border of the thigh and further continues as the saphenous nerve
