Medial Thigh

Question 1

what muscles are located in the medial thigh

Answer 1

adductor longus

adductor brevis

adductor magnus

gracilis

obturator externus

Question 2

what is the nerve rule of the medial thigh

Answer 2

obturator nerve

Question 3

what is the exception to the nerve rule

Answer 3

superficial part of the adductor magnus

innervated by tibial nerve

Question 4

adductor longus origin and insertion

Answer 4

O: superior pubic ramus and anterior side of the symphysis

I: femur (linea aspera and medial lip in the middle third of the femur)

Question 5

adductor longus innervation

Answer 5

obturator nerve (L2,L4)

Question 6

adductor longus action

Answer 6

Hip joint: ADD, flexion (up to 70 degrees), EXT (past 80 degrees of flexion), stabilizes the pelvis in the coronal and sagittal planes

Question 7

adductor brevis origin and insertion

Answer 7

O: inferior pubic ramus

I: femur (linea aspera and medial lip in the middle third of the femur)

Question 8

adductor brevis innervation

Answer 8

obturator nerve (L2,L3)

Question 9

adductor brevis action

Answer 9

Hip joint: ADD, flexion (up to 70 degrees), EXT (past 80 degrees of flexion), stabilizes the pelvis in the coronal and sagittal planes

Question 10

adductor magnus origin

Answer 10

inferior pubic ramus

ischial ramus

ischial tuberosity

Question 11

adductor magnus insertion

Answer 11

deep part: medial lip of the linea aspera

superficial part: adductor tubercle of femur

Question 12

deep part of the adductor magnus

Answer 12

fleshy insertion

Question 13

superficial part of the adductor magnus

Answer 13

tendinous insertion

Question 14

adductor magnus innervation

Answer 14

deep part: obturator nerve (L2,L4)

superficial part: tibial nerve (L4)

Question 15

adductor magnus action

Answer 15

hip: ADD, EXT, slight flexion, IR (superficial part), stabilizes the pelvis in the coronal and sagittal plane

Question 16

gracilis origin and insertion

Answer 16

O: inferior pubic ramus below the symphysis

I: tibia (pes anserine), medial border of the tuberosity

Question 17

gracilis innervation

Answer 17

obturator nerve (L2,L3)

Question 18

gracilis action:

Answer 18

hip: ADD and flexion

knee: flexion and IR

Question 19

obturator externus origin and insertion

Answer 19

O: outer surface of the obturator membrane and its bony boundaries

I: trochanteric fossa of the femur

Question 20

obturator externus innervation

Answer 20

obturator nerve (L3,L4)

Question 21

obturator externus action

Answer 21

hip: ADD, ER, stabilizes pelvis in the sagittal plane

Question 22

obturator artery

Answer 22

from internal iliac artery through obturator foramen

Question 23

what artery does the obturator artery help

Answer 23

helps femoris profundus supply the adductor muscles

via anterior and posterior branches

Question 24

posterior branch of the obturator artery

Answer 24

gives off acetabular branch that supplies the head of the femur

Question 25

veins of the medial thigh

Answer 25

accompanying arteries

Question 26

nerves of the medial thigh

Answer 26

obturator (anterior and posterior divisions) (names based off of adductor brevis muscle) provides motor and sensory to superomedial thigh

Question 27

pes anserine

Answer 27

attachment point for sartorius, gracilis, semitendinosus one muscle from each compartment attaches here Say Grace before Tea (order the muscles are in more lateral to more medial)
