Gluteus medius, gluteus minimus, and tensor fascia lata ms. _______ rotate the thigh
medially
stance phase
medially rotate
swing phase
laterally rotate
Which small lateral rotator is least effective abductor when thigh is flexed?
Quadratus femoris m.
Articularis genu m. function
pulls suprapatellar bursae superiorly during knee extension
Which muscles insert on Pes Anserinus/which compartments/what are their innervations
Sartorius m./anterior compartment/ femoral N.
Gracilis m./medial compartment/obturator N.
Semitendinosus m./posterior compartment/sciatic N.
what separates the fibular collateral ligament from the lateral meniscus?
popliteus tendon
oblique popliteal ligament arises from
tendon of semimembranosus m.
unhappy triad
anterior cruciate L., tibial collateral L., lateral meniscus
deltoid ligament is made up of
anterior tibiotalar L.
posterior tibiotalar L.
tibionavicular L.
tibiocalcaneal L.
which ligament goes first in inversion ankle sprain
anterior talofibular L.
high ankle sprain ligaments?
posterior tibiofibular L.
anterior tibiofibular L.
where is the foot amputated?
transverse tarsal joint (talonavicular joint and calcaneocuboid joint)
fibrous joint
bones are held together by dense regular CT
cartilaginous joint
bones are joined by cartilage
synovial joint
has fluid-filled synovial cavity, bones enclosed with capsule, joined by various ligaments
syndesmosis
fibrous joint (interosseous membrane)
two types of cartilaginous joints
synchondrosis: hyaline between bones (epiphyseal plates)
symphysis: fibrocartilage between bones (pubic sympysis, IV disks)
first-class lever
fulcrum in the middle (scissors, neck movement)
second-class lever
load in the middle (wheelbarrow, toe raises)
third-class lever
effort is in the middle (biceps brachii, biceps femoris)
change efficiency by
changing difference between load and effort (move closer to make more efficient, but slower)
