lower limb muscles

Question 1

what is the iliopsoas group (movement and function)

Answer 1

-includes psoas major and minor and iliacus muscle
-strong hip flexor
-flexion of thigh at hip and flexion of vertebral column when lower limb is planted

Question 2

rectus femoris movement

Answer 2

part of our quadriceps
-flexion of thigh at hip
-extension of leg at knee

Question 3

muscles that causes flexion of thigh at hip besides iliopsoas and rectus femoris

Answer 3

-sartorius
-adductor longus and adductor magnus (anterior)

Question 4

gluteal group

Answer 4

-gluteus maximus: extension, lateral rotation, abduction (upper fibres only)
-gluteus medius/minimus: abduction and medial rotation

Question 5

what does the glute max stabilize

Answer 5

the knee when the leg is extended
- it insertion is at the iliotibial tract

Question 6

adductor group

Answer 6

adductor brevis, longus, magnus, pectineus, gracilis
*all except pectineus do medial rotation
*gracilis causes flexion of leg at knee

Question 7

lateral rotator group

Answer 7

little muscles below glute max…
-cause lateral rotation
*all except quadratus femoris causes abduction of thigh at hip

Question 8

quadriceps movement and muscles

Answer 8

all cause extension of leg at knee, insert at tibial tuberosity
-rectus femoris, causes flecion of thigh at hip too
-vastus lateralis and medialis
-vastus intermedist

Question 9

hamstring muscles and movement

Answer 9

all cause flexion of leg at knee and extension of thigh at hip
-semimembranosus, medial rotation
-semitendinosus, medial rotation
-bicep femoris, lateral rotation

Question 10

gracilis muscle movement

Answer 10

-adduction of thigh at hip
-flexion of leg at knee
-medial rotation of hip and knee

Question 11

locking of knee

Answer 11

popliteus m. contract= medial rotation of tibia which then unlocks the joint

Question 12

triceps surae (gastrocnemius and soleus)

Answer 12

-plantar flexors of the foot
-soleus is a synergist
-gastrocnemius causes flexion of leg at knee
-insert on the calcaneus via the Achilles tendon

Question 13

what muscles cause plantar flexion

Answer 13

-gastrocnemius
-soleus
-plantaris
-fibularis longus/ brevis
-tibialis posterior

Question 14

what muscle causes dorsiflexion

Answer 14

tibialis anterior

Question 15

what muscles cause inversion and eversion of foot

Answer 15

inversion: tibialis anterior/ posterior
eversion: fibularis longus/brevis

Question 16

tensor fascia latae muscle movement

Answer 16

medial rotation of thigh at hip and abduction
