1. Linea Aspera | 2. Adductor Tubercle
31
Adductor Magnus Action?
1. Adducts thigh | 2. Posterior fibers extend and laterally rotate the thigh
32
Adductor Magnus Nerve?
1. Anterior Fibers: Obturator Nerve (L2-L4) | 2. Posterior Fibers: Tibial Nerve (L4)
33
Adductor Longus Proximal?
Anterior surface of Pubis, just inferior to the Pubic Ramus
34
Adductor Longus Distal?
Medial lip of Linea Aspera on middle third of femur
35
Adductor Longus Action?
1. Adducts thigh | 2. Flexes hip from extended position
36
Adductor Longus Nerve?
Obturator Nerve (L2-L4)
37
Adductor Brevis Proximal?
Pubis
38
Adductor Brevis Distal?
1. Proximal Portion of Linea Aspera | 2. Pectineal Line
39
Adductor Brevis Action?
1. Adducts thigh | 2. Flexes hip from extended position
40
Adductor Brevis Nerve?
Obturator Nerve (L2-L4)
41
Gracilis Proximal?
Pubis (Inferior Pubic Ramus)
42
Gracilis Distal?
1. Medial surface of proximal Tibia, inferior to Tibial Condyle 2. Pes Anserinus
43
Gracilis Action?
1. Adducts thigh 2. Flexes knee 3. Medially rotates Tibia
44
Gracilis Nerve?
Obturator Nerve (L2-L4)
45
Pectineus Proximal?
Pectineal line of Pubis
46
Pectineus Distal?
Pectineal line of Femur
47
Pectineus Action?
1. Hip adduction 2. Flexes thigh 3. Medially rotates thigh
48
Pectineus Nerve?
Femoral Nerve (L2-L3)
49
What is important about the pubic symphysis?
- Fibrocartilage that allows pelvis to expand during childbirth - Hormones called Relaxins work on it
50
What defines the borders of the hip joint capsule?
- Greater Trochanter - Lesser Trochanter - Intertrochanteric line - Intertrochanteric crest
51
Why are the femoral condyles different sizes?
- medial condyle is bigger - pelvis is wide which pushes the femoral head out from main axis - lower leg needs to be perpendicular to the ground so the femur is angled to compensate
52
Importance of Adductor Tubercle and Adductor Hiatus?
- Adductor Magnus attaches to Adductor Tubercle and Linea Aspera - creates opening for the Femoral Artery to travel through Adductor Hiatus from anterior to posterior thigh and become the Popliteal Artery
53
Importance of the patella and the patellar tendon?
- serve as a pulley, has synovial fluid - increases lever arm of the leg and allows it to extend more - allows force vector to point down
54
Lumbosacral plexus? Lumbar plexus? Sacral plexus?
Lumbosacral: T12-S3 Lumbar: T12-L5 Sacral: S1-S3
55
Lateral Femoral Cutaneous nerve roots? Innervation?
L2-L3 - travels underneath inguinal ligament - innervates skin on lateral portion of thigh
56
Sciatic Nerve roots?
L4-S3
57
Femoral Nerve roots? Innervation?
L2-L4 - posterior division, but innervates anterior thigh - travels underneath inguinal ligament - innervates quad muscles, sartorius, pectineus - cutaneous innervation for most of anterior thigh - continues as saphenous nerve to innervate skin of lower leg on medial side
58
Obturator Nerve roots? Innervation?
L2-L4 - goes through Obturator Foramen, innervates adductor muscles - (part of adductor magnus innervated by sciatic nerve) - Innervates skin on medial thigh, small portion
59
Branches of Femoral Artery?
- Deep Femoral Artery - Medial and Lateral Circumflex arteries come off Deep Femoral to anastomose around the femoral head - Medial runs posterior and supplies most of Femoral head - Lateral runs anterior
60
5 branches of Popliteal Artery?
-continuation of Femoral Artery 1. Superior Lateral Genicular 2. Superior Medial Genicular 3. Middle Genicular 4. Inferior Lateral Genicular 5. Inferior Medial Genicular -these arteries anastomose around knee
61
Gait Cycle?
single sequence of function of one limb
62
Stance phase of gait?
limb in contact with ground
63
Swing phase of gait?
foot in air for limb advancement
64
What are the major hip flexors?
- Psoas Major - Iliacus - Sartorius - Rectus Femoris
65
Why is the Vastus Medialis bigger than the Lateralis?
keep patella from dislocating laterally
66
Boundaries of Femoral Triangle?
Superior: Inguinal Ligament Medial: Adductor Longus Lateral: Sartorius Floor: Iliopsoas and Pectineus Roof: Fascia Lata, Subcutaneous tissue and skin
67
Contents of Femoral Triangle?
- Femoral Nerve and branches - Femoral Sheath - Femoral Artery and Vein - Femoral Canal (lymph nodes)
68
Adductor Canal boundaries?
Superior: Apex of Femoral Triangle Anterior and Lateral: Vastus Medialis Posterior: Adductor Longus and Magnus Medial and Roof: Sartorius
69
Contents of Adductor Canal?
- Femoral Artery and Vein - Saphenous Nerve (cutaneous) - Nerve to Vastus Medialis (last branch of Femoral Nerve)
