Question 10

flexor digitorum profundus

Answer 10

flexion @ wrist and some fingers

Question 11

flexor pollicis longus

Answer 11

flexion @ thumb

Question 12

extensor digitorum

Answer 12

flexion @ fingers and wrist

Question 13

lower limbs

Answer 13

-muscles that move thigh
-muscles that move leg
-muscles that move foot/ toes

Question 14

muscles that move thigh

Answer 14

-gluteal group
-lateral rotator group
-adductor group
-iliospoas group

Question 15

gluteal group

Answer 15

-maximun: hip ext
-medius: abduction @ hip
-minimus: abduction @ hip
-tendor fasciae latae: adbuction @ hip

Question 16

lateral rotator group

Answer 16

-piformis: lateral rotation and hip abduction
-under the gluteus minimus
-spasms= sciatica bc sciatic nerve is there

Question 17

adductor group

Answer 17

GAP
-gracilis: flex/ medial rotate knee and hip
-adductor brevi, adductor longus, adductor magnus: hip adduction
-pectineus: flex/ adduct hip

Question 18

iliopsoas group

Answer 18

-iliacus: flex hip
-psoas major: flex hip

Question 19

move the leg muscles

Answer 19

knee extensors
-3 vastus/ quads
-vastus intermediate, vastus lateralis and vastus medialis: extend lower leg
-rectus femoralis: extend/ flex lower leg
flexors
-hammstrings
-biceps femoris: bend leg and ext hip
-semi memranosus and semi tendinosus: flex lower leg
-popliteus: flex lower elg

Question 20

muscles move feet and toes

Answer 20

-extrinsic
-tibialis anterior: dorsal flex lets you stand on your heels
-come from leg
-gastrocnemius: plantar flexation
-intrinsic
-originate on the foot

Question 21

calcaneus tendon

Answer 21

achillies

Question 22

fascia

Answer 22

connective tissue around individual muscle

Question 23

deep fascia

Answer 23

separate muscles into compartments

Answer 25

arm
-anterior and posterior compartments
forearm
-anterior, lateral and posterior compartments

Question 26

anterior compartments

Answer 26

-bicep brachii
-brachialis
-coracobrachialis

Question 27

posterior compartment

Answer 27

-triceps brachii

Question 28

anterior forearm compartment

Answer 28

-superficial and deep

Question 29

compartment syndrome

Answer 29

-bleeding into anterior or posterior compartment
-muscle swells
-need fasciotomy to relieve pressure (cut through swollen fascia)
