Lower Limbs Flashcards
articulations of tibia
superior: condyles of femur
inferior: talus
articulations of fibula
superior: tibia
inferior: ASK – not clear
bones of the thigh
femur
main function of knee ligaments
prevent hyperextension
bursitis
inflammation of the bursa; can be caused by injury, infection, and exercise
surface anatomy of fibula
- head
- neck
- lateral malleolus
gluteal fold
where the butt meets the thigh
general function of lower limb
- organ of locomotion
- weight bearing
- maintaining balance
spray of vessels at neck of femur
branches of femoral artery
line of gravity in the body releative to lower limb
- behind the hip joint
- in front of hip joint
varicose veins
dilated, lengthened, twisted veins
anterior tibial artery serves:
serves the anterior elevator muscles
fascia lata
membranous layer of fascia that surrounds the thigh muscles
formal name for bruise
contusion
what does the buttocks refer to?
the gluteal region; posterior prominence on each side of the body; made up of gluteal muscle and CT
problem with varicose veins
- dilation can be a problem because it can lead to pooling
- issues of edema or muscle cramps
bones of the leg
tibia (on medial side) and fibula (on lateral side)
fascia of thigh
superficial fascia
- fatty layer
- membrane layer
function of fibula
muscle attachment site and stabilizes ankle
surface anatomy of tibia
- medial malleolus
- medial condyle
- tibial tuberosity <– really important landmark
main movementes of ankle joint
dorsiflexion
- produced by muscles in anterior compartment of leg (i.e. tibialis anterior, ex. hallucis longus, ext. digitorum longus)
plantarflexion
- produced by muscles in posterior compartment of leg (i.e. gastrocnemius, soleus, flexor digitorum longus, flexor digitorum hallucis, tibialis posterior)
interosseus membrane
membrane between the tibia and fibula
tibiocondylar cavity
located between each femoral condyle and tibia
borders of the thigh
- extends from hip to knee
- anterior: inguinal ligament to knee
- posterior: gluteal fold to popliteal fossa
why is there so much stress on the knees?
bipedal posture puts a lot of stress on the knees out of virtue of the knees not being located directly beneath the hips and, instead, sitting at an angle to the hips
we have a stability weakness between the hip and knee
role of menisci
- cushion the knee joint
- shock absorption
- help distribute body weight
- helps to fill the gap between condyles and tibia
- evenly distribute synovial fluid
- provide some joint stability
patellar hammer reaction – what’s wrong if there’s no reaction
- patellar ligament is what gets hit during a doctor’s visit to check for reaction
- tests leg extension – the following could be wrong if there’s no reaction
- quadricep muscles and femoral nerve
- spinal rami: L2, L3, and L4
function of the butt
- food storage organ during pregnancy
- sexual stimuli releaser
