|
Pectineus
|
-->INNERVATION: femoral n. and sometimes the obturator n.

|
Pes Anserinus
|
common tendon of the :
Gracilis Sartorius Semitendinosus Insertion onto the medial tibia |
|
Adductor magnus
|
-->has both a hamstring and an adductor component
HAMSTRING COMPONENT: arises from the ischial tuberosity; innervated by the tibial n. |
|
Obturator Internus Action
|
lateral rotator of the hip
|
|
Hamstring compartment
|
Semitendinosus
Semimembranous Biceps Femoris Adductor magnus (portion) -->innervation via TIBIAL N. -->enclosed by the FASCIA LATA, unnamed compartment, and the LATERAL INTERMUSCULAR SEPTUM -->MAIN ACTION: flex knee and extend the thigh |
|
Biceps femoris
|
-->arises from the femur and lateral intermuscular septum
-->innervated by the COMMON FIBRILAR N. which is a branch of the sciatic n. |
|
Common FIbrilar Nerve
|
-->branch of the Sciatic N.
-->innervates the Biceps Femoris |
|
Femoral Triangle
|
-->inguinal
-->medial border of the Sartorius -->lateral border of the Adductor Longus ROOF: skin, tela subcutanea, fascia lata FLOOR: iliopsoas, pectineus, adductor longus |
|
Femoral Sheath
|
Femoral artery, vein and sheath
Lymph nodes -->continuous with the TRANSVERSALIS FASCIA (anteriorly) and the ILIAC FASCIA (posteriorly) Does NOT contain Femoral Nerve |
|
Femoral Canal
|
-->most medial compartment within the femoral sheath
-->extends distally to the SAPHENOUS HIATUS --> allows for expansion of the femoral vein at times of increased venous return |
|
Femoral Ring
|
-->abdominal opening of the femoral canal
LATERAL: femoral vein ANTERIOR: inguinal ligament MEDIAL: lacunar ligament POSTERIOR: pubis covered by pectineal ligament and pectineus muscle |
|
Femoral Hernia
|
protrusion of the abdominal contents through the femoral ring
may herniate through the saphenous ring into the tela subQ. |
|
Adductor Canal
|
(Hunter's Canal)
tunnel deep to the middle 1/3 of the SARTORIUS muscle begins where the sartorius crosses the adductor longus ends at the adductor hiatus in the tendon of the adductor magnus CONTENTS: femoral artery/vein, saphenous vein, saphenour nerve, n. to vastus medialis |
|
Femoral Artery
|
BEGINS: inguinal ligament where exits femoral canal--->from EXTERNAL ILIAC ARTERY
ENDS: as the POPLITEAL via adductor hiatus BRANCHES: Descending Genicular A. Profunda Femoris A. |
|
Profunda Femoris A.
|
--> branch of the Femoral A. close to the exit of the femoral a. through the inguinal canal
-->gives off: 1. Medial Femoral Circumflex A.: supplies head and neck of femur 2. Lateral Femoral Circumflex A. |
|
Cruciate Anastomosis
|
-->in posterior aspect of the thigh
-->involves following: Inferior Gluteal A. Medial and Lateral Femoral Circumflex A. First Perforating Branch of Profunda Femoris A. -->collateral route of circulation should femoral a. be occluded |
|
Femoral Nerve
|
--> L2-L4
--> derived from the dorsal part of the plexus -->goes to the anterior compartment of the leg and medial aspect of the leg INJURY = WEAKNESS/LOSS OF SENSATION AT THE KNEE |
|
Obturator Nerve
|
---> L2-L4
--> derived from the VENTRAL part of plexus -->supplies the ventral muscles (adductor) of thigh --> supplies the hip and knee joint HIP PAIN REFERRED TO KNEE |
|
Sciatic Nerve
|
1. Common Tibial Nerve (L4-S3)
---->derived from the ventral part of the sacral plexus 2. Common Fibular Nerve (L4-S2) ----->derived from the dorsal part of the sacral plexus and to the dorsal musculature (short head of biceps) |
