Q
Fascia Lata - 4 parts
A
- most superior portion of deep fascia - surrounds the thing and portion of gluteal region
Includes:
- Gluteal Aponeurosis: forms intermuscular septum between gluteus maximus and medius muscles
- Intermuscular Septa: inward projections that extend to femur and delineate musc. compartments
- Iliotibial Tract: lateral thickening of fascia lata - serves as tendon for tensor fascia lata and gluteus maximus muscle
- saphenous vein opening
2
Q
Deep Tendon Reflexes
A
- Quadriceps: L3/L4**
- Achilles: S1**/S2
3
Q
Cural Fascia - includes 4 things
A
- extension of fascia below the knee
Includes:
- Intermuscular septa: anterior and posterior attach as inward extensions of crural fascia to fibula - delineate anterior and lateral crural compartments. Transverse attaches between the tibia and fibula posteriorly and delineates superficial and deep posterior compartments
- Retinacula: thickening of crural fascia which prevents tendons from bowstringing
- fascia of dorsum of the foot
- plantar fascia - includes plantar aponeurosis
4
Q
Anterior Femoral Compartment
A
- majority of muslces (quads and sartorius) flex the thing and extend the leg
- branches of femoral a. and n.
5
Q
Femoral Triangle
A
- transitional space b/w abdominoplevic region and lower limb
- boundaries: inguinal ligament, sartorius and adductor longus muscle, covered by fascia lata
- contains: femoral vein, femoral artery, nerve and deep inguinal lymph nodes
6
Q
Medial Femoral Compartment
A
- muscles here flex, adduct and rotate thigh
- branches of obturator a. and n.
7
Q
Adductor Canal (“subsartorial”, Hunter’s)
A
- canal connecting femoral triangle with popliteal fossa
- bounded by adductor musculature, vastus medialis and sartorius muscle
- contains femoral a. , v. , saphenous n. and nerve to the vastus medialis
8
Q
gluteal compartment
A
- superficial:
- (muscles like deltoid) - abduct, flexes and medially rotates, extends and laterally rotates the thigh
- deep:
- contains muscles which abduct and laterally rotate the thigh
- gluteal aa. and nn.
- sciatic nerve transverses the entire length of this compartment to gain the posterior thing
9
Q
Posterior Femoral compartment
A
- muscles (hamstrings) - flex the leg and extend the thigh
- branches of deep femoral a. and v.
- sciatic n. traverses the entire length of this compartment and provides innervation to all its musculature
10
Q
Popliteal Fossa
A
area posterior to knee; transitional zone for structures passing from thing to leg
- bounded by semimembranosus, semitendinosus, biceps femoris and gastrocneumius muscles and covered by fascia lata
- contains popliteal a., popliteal v, bifurcation of sciatic nerve into its commmon fibular and tibial branches
11
Q
Posterior Crural compartment
A
Superficial: gastrocnemius, soleus, plantaris - which flex leg and plantar flex foot
Deep: muscles plantar flex and invert foot
- tibial n. and posterior tibial a. distribute to this compartment
12
Q
Lateral Crural compartment and dorsum of foot
A
- muscles plantar flex and evert the foot
- branches of superficial fibular n. and fibular a.
13
Q
anterior crural compartment and dorsum of foot
A
- contains muscles which dorsi flex and invert he foot - extend the toes and assist in eversion of the foot
- deep fibular n. and anterior tibial a.
14
Q
Plantar foot
A
- 4 compartments
- Medial (great toe - hallux)
- Lateral (small toe - digit minimi)
- central
- interosseous
- posterior tibial a. bifurcates to form lateral and medial plantar aa. which distribute to these compartments
- tibial n. bifurcates –> lateral and medial plantar nn.
15
Q
Femoral A.
A
- enters femoral triangle from abdominopelvic cavity deep to inguinal ligament
- enters adductor canal in order to travel posteriorally to popliteal fossa
- becomes popliteal a. after leaving adductor canal - provides collateral branches to knee joint: when leaving popliteal fossa, bifurcates to form anterio and posterior tibial a.
