Motion
Identify the motion at the hip, muscles active and the innervation for the these muscles
Hip flexion
Iliopsoas (iliacus and psoas major) and rectus femoris
Both innervated by Femoral NerveDefine dorsiflexion and plantarflexion. What plane of motion do these occur in?
Dorsifelxion: Toes move towards shin
Plantarflexion: Toes move away from shin
Sagittal plane
On the following picture, identify the colored structure
Pubis
What innervates Serratus Anterior? Identify the roots
Long Thoracic Nerve
Roots C5, C6, C7
What type of blood vessels carry deoxygenated blood?
Purpose of the PCL
Prevents posterior translation of tibia on femur
The fibula is ____ to the tibia
Lateral
L or R, anterior or posterior
L scapula anterior surface
Distinguish between the quardiceps tendon and the patellar tendon/ligament
Quadriceps tendon: Quadriceps to patella (more superior)
Patellar tendon/ligament: Continuation of quad tendon, patella to tibial tubercle (tuberosity)
What composes the unhappy triad
MCL, ACL, and Medial Meniscus
What is the purpose of the meniscus?
Act as a shock absorber for the knee
Identify the muscle that originates here and it's actions
Gluteus Medius
Hip abduction and hip external rotation
When you bend your knee, which way does the patella move?
Inferior
Identify the muscles that make up the anterior thigh and identify their common action
Quads:
Rectus femoris, Vastus Lateralis, Vastus Intermedius, Vastus MedialisFrom medial to lateral what is the relationship between the femoral artery, vein, and nerve?
VAN
Vein, artery, nerve
What structure would be injured by the knee receiving a medial force
LCL
Define Concentric, Eccentric, and Isometric and name the steps of analyzing a movement video
Concentric: Muscle shortens, lifting weight
Eccentric: Muscle lengthens, lowering weight
Isometric: Muscle's length does not change, holding weight
1. How does resistance (often gravity) want joint to move?
2. Muscle group that moves joint opposite resistance is active
3. Is there motion at the joint?
4. No motion = Isometric Contraction
5. Motion against Resistance = Concentric Contraction
6. Motion with Resistance = Eccentric Contraction
Left Tibia and tibial tuberosity
Name the rotator cuff muscles and what they are each innervated by
Supraspinatus: Suprascapular Nerve
Infraspinatus: Suprascapular Nerve
Teres Minor: Axillary Nerve
Subscapularis: Upper & Lower Subscapular Nerves
Name the roots of the nerve that innervates glute max
Nerve = Inferior Gluteal Nere
Roots = L5, S1, S2
Name the muscle responsible for this motion. Identify Origin, Insertion, and Innervation
Rectus Femoris
O: AIIS, ilium superior to acetabulum
I: Tibial Tuberosity
Innervation: Femoral nerve L2, L3, L4
Using the terms medial and lateral distinguish between valgus and varus
Valgus: Joint medial to joints above and below
Varus: Joint lateral to joints above and below
Identify structures 1-3
1. Ischial tuberosity
2. Lesser trochanter
3. Lateral femoral condyle
What innervates adductor magnus?
- Obturator nerve L2-L4 (adductor portion)
- Sciatic nerve tibial portion L4 (hamstring portion
List the blood vessels of the knee
Aorta --> Iliac artery --> femoral artery --> popliteal artery --> anterior tibial artery and posterior tibial artery
