muscles of the hip and thigh

Question 1

fascia lata

Answer 1

deep fascia that invests the thigh “sausage casing”

Question 2

iliotibial tract

Answer 2

thickened, LATERAL, portion of the fascia lata

Question 3

what are the superficial gluteal muscles?

Answer 3

gluteus maximus, gluteus medius, gluteus minimus, and the tensor fasciae latae

Question 4

what are the deep gluteal muscles?

Answer 4

deep lateral rotators- includes piriformis

Question 5

in general, what are the superficial and deep gluteal muscles responsible for in general?

Answer 5

abduction of the hip

Question 6

what innervates the gluteus maximus

Answer 6

inferior gluteal nerve

Question 7

what innervates the gluteus medius, minimus, and tensor fascia latae

Answer 7

superior gluteal nerve

Question 8

what are the exact other actions of gluteus maximus

Answer 8

extend hip (thigh) and lateral rotation of hip (thigh)

Question 9

describe the roles of the gluteal muscles for pelvic stabilization

Answer 9

contraction of the gluteus medius and minimus mm prevents an excessive pelvic tilt when one raises their leg

Question 10

what do gluteus medius and minimus being paralyzed mean?

Answer 10

hip drop

Question 11

what affects stabilization

Answer 11

damage to the superior gluteal nerve

Question 12

exact other actions of the tensor fasciae latae

Answer 12

flexing of the hip (thigh)

Question 13

what are the deep gluteal muscles responsible for?

Answer 13

lateral rotation of the hip (thigh) and help stabilize the hip joint

Question 14

piriformis muscle action

Answer 14

lateral rotation of hip (thigh)

Question 15

two major anterior hip muscles

Answer 15

psoas major
illiacus muscle
*remember join together to form one tendon that attaches to the lesser trochanter!

Question 16

anterior hip muscles (iliopsoas) action

Answer 16

flex the hip joint and flex the trunk

Question 17

psoas major m. innervation

Answer 17

lumbar spinal nerve

Question 18

iliacus muscle innervation

Answer 18

femoral nerve

Question 19

the thigh muscles are compartmentalized into

Answer 19

anterior, medial, and posterior groups

Question 20

anterior thigh muscles consist of

Answer 20

-sartorius m.
-Quadriceps femoris mm. (which includes: rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius

Question 21

all muscles of the anterior thigh are innervated by

Answer 21

femoral nerve

Question 22

all anterior thigh muscles provide what action, besides what muscle

Answer 22

knee (leg) extensors
besides: sartorius m.

Question 23

what are the actions completed by the sartorius muscle?

Answer 23

flex hip (thigh)
flex knee (leg)

Question 24

what is special about the rectus femoris?

Answer 24

is crosses the hip joint so it flexes the thigh (hip)

Question 25

what are the medial thigh muscles?

Answer 25

gracilus pectineus adductor longus adductor brevis adductor magnus

Question 26

what are the majority of medial thigh muscles innervated by?

Answer 26

obturator nerve

Question 27

what do the medial thigh muscles do?

Answer 27

ADDuct the hip (thigh)

Question 28

what is special about the pectineus'?

Answer 28

is also flexes the hip (thigh), because of this it is also innervated by the femoral nerve

Question 29

what is apart of the adductor magnus that allows vessels to pass through from posterior to anterior?

Answer 29

adductor hiatus

Question 30

what are the posterior thigh muscles?

Answer 30

"hamstring muscles" Biceps femoris -long head -short head* Semitendinosus m. Semimembranosus m.

Question 31

what are the majority of the posterior thigh muscles innervated by?

Answer 31

tibial n.

Question 32

what is the exception, the biceps femoris short head innervated by?

Answer 32

common fibular n. * it only crosses the knee so it can only flex the leg (knee)

Question 33

posterior thigh muscles actions?

Answer 33

extend hip (thigh) flex knee (leg)

Question 34

what is the pes anserine and what muscles does it consist of?

Answer 34

the conjoined tendon of three muscles that insert on the proximal tibia 1) sartorius m 2) Gracilis m 3) semitendinosus m
