Pre-axial

The pubis and ischium are anterior elements and muscles from them are therefore innervated by anterior branches of the lumbosacral plexus (obturator nerve L2,3,4 and tibial nerve L4, L5, S1, S2, S3)

Post- axial

The femur and illium are posterior elements and muscles from them are innervated by posterior branches of the lumbosacral plexus (Femoral L2, L3, L4 and common fibular nerve L3, L4, S1, S2)

IT tract

Iliotibial tract is lateral fascia lata that extends from ilium to tibia. Reinforced by tensor fascia lata and gluteus maximus.

Muscles of Anterior Thigh

These are innervated by the femoral nerve L2-4 EXCEPT the tensor fascia lata. These are post-axial in embryonic origin.

Quadriceps femoris (rectus femoris, vastus lateralis, vastus intermedius, and vastus medialis)

Iliopsoas

Sartorius

Muscles of Medial Thigh

Pre-axial in embryonic origin so innervated by the oburator nerve L2-4.

Pectineus

Gracilis

Adductor longus

Adductor brevis

Adductor magnus

Obturator externus

Femoral Triangle (Site of femoral hernia)

Superior border: inguinal ligament
Lateral border: sartorius
Medial border: adductor longus
Floor: pectineus, iliopsoas
Roof: fasia lata

Contents: NAVEL, Femoral Nerve, Femoral Artery, Femoral Vein, Empty space (femoral canal), and Lacunar ligament

Adductor Canal/ Hunter's canal

begins at apex of femoral tri.
Postmed: adductor longus and magnus
Ant: sartorius
Lat: vastus med

Femoral art, vein, saphenous n (cutaneous branch of fem), nerve to vastus medialis

After passing adductor hiatus in knee, femoral vessles turn into popliteal

Cutaneous innervation of Anterior Thigh

Med and intermed cutane branch from femoral to supply anterior and medial thigh.

Lateral femoral cutaneous n. enters thigh near ASIS

Ilioinguinal n and genitofemoral n. (femoral branch) supply inferior to inguinal lig.

Obterator n. does medial thigh

Profunda femoral artery

branch of the femoral artery which passes between the adductor longus and pectineus muscles to run along femur.

Branches into lateral femoral circumflex and medial femoral circumflex.

Lateral has ascending, transverse and descending branches

Where do the femoral and obturator arteries branch from

Femoral branches from the external iliac artery while the obturator artery arises from the internal iliac artery w/in the pelvis and passes through the obturator foramen

Femoral supplies anterior compartment
Obturatory supplies medial compartment

Superior Horizontal Lymph

located below and ajacent to injuinal lig, get drainage from perineum, external genital structures, distal vagina, distal anal canal, anterior abdominal wall, and gluteal region

Inferior Vertical Lymph group

Inferior group along termination of great saphenous get lower limb drainage except a few draining into popliteal nodes

Deep inguinal nodes

lie deep to fascia lata and get drainage of superficial nodes

A: Major flexor of thigh
In: Femoral Nerve L2, L3, L4
Art: Femoral Artery

Sartorius

O: ASIS (only one)
I: medial surface of tibia below tuberosity
A: abducts, flexes, and laterally rotates; also flexes leg at knee joint
In: Femoral Nerve L2, L3, L4
Art: Femoral Artery

Pectineus

O: pubic body
I: middle part of the linea aspera
A: adducts and flexes thigh
In: Obturator nerve (L2, L3, L4)
Art: Obturator artery
