Anatomy of LL Flashcards
(41 cards)
Why does the sacrum tilt slightly forward
Line of gravity. We have a lot of ligaments to prevent this
What is symphysis e.g. pubic symphsis
Cartilaginous joint
Where is the sacroilliac joint
Picture
What kind of joint is the hip
Ball & socket
Where is the acetabulum
Between head of femur and illium
What is the main purpose of ligamentum teres
To supply the blood vessels (artery) in the head of the femur
What’t the thicker lower limb bone (tibia or fibula)
Tibia
What is a condyloid joint
Biaxial joint where one range of movement is greater than the other e.g. the knee
Where are the meniscii
Between the tibia & femur
What is the purpose of the menisci
Shock absorption, improved fit, lubrication, prevention of arthritis
What are the cruiciates
Crossing ligaments in the knee (crossing from anterior to posterior and vice versa). Join femur & tibia
What is PCL & ACL
PCL = posterior cruciate ligament, provides anterior slide of femur on tibia
ACL = anterior cruciate ligament, prevents hyperextension
What movement does the lateral collateral ligament prevent
Adduction
What movement does the medial collateral ligament prevent
Abduction
What joint allows in/eversion
Subtalar joint (talus, calcaneus, navicular all working together)
Where is the iliopsoas muscle & what movements
Picture, flexion at hip
Label thigh compartments on MRI
Lab notes
What are bi-articular muscles
Muscles that can produce movement at 2 joints (hip & knee). Quads and hamstrings. If you use both at once they’re usually doing the opposite
What muscle is right next to the tibia
Tibialis anterior
What actions can the tibia do
Dorsiflexion & inversion
What are the actions at the calcaneous
Plantarflexion
What’s between the tibia & fibula
Interosseous membrane
Label compartments of the leg
Lab notes
What nerve is in the anterior compartment of the thigh & what are it’s movements
Femoral nerve
Hip flexion & knee extensino
