Answer 1

AAA PG

adductor longus
adductor brevis
adductor magnus
pectinius
gracilis

Question 2

what are the extrinsic muscles of posterior compartment of thigh?

Answer 2

obturator externis, which lies deep in this region

Question 3

what are composite muscles?

Answer 3

musce that have dual innervations

Question 4

what are the composite muscles of the medial compartment?

Answer 4

pectinius- supplied by femoral and obturator nerve

adductor magnus -obturator nerve (posterior division) and tibial part of sciatic nerve

Question 5

nerve supply of medial compartment of thigh?

Answer 5

obturator nerve, accessory obturator nerve

Question 6

arterial supply of medial compartment of thigh

Answer 6

obturator artery
medial circumflex artery

Question 7

what is rider’s bone?

Answer 7

the rounded end of adductor longus gets calcified due to friction with the horseback

Question 8

which is the most superficial muscle of the medial compartment?

Answer 8

gracilis

Question 9

which muscle is commonly used in reconstructive srgeries and transplantation?

Answer 9

grscilid
often used for transplantation f external anal shincter

Question 10

what is adductor hiatus?

Answer 10

it is a large ossoaponeurotic gap between adductor magnus and shaft of femur

Question 11

what is the significance of adductor hiatus?

Answer 11

allows passage of femoral vesssels from adductor canal to popliteal fossa

Question 12

upper 4 osseoaponeurotic openings give passage to _____________________ arteries

Answer 12

perforating branches of profunda femoris artery

Question 13

chief nerve of medial compartment of thigh?

Answer 13

obturator nerve

Question 14

root value of obturator nerve?

Answer 14

originates from lumbar plexus

ventral divison of anterior primary rami of spinal nerves L2 - L4

proximal part lies in pelvis

Question 15

describe the path of anterior divison of obturator nerve

Answer 15

it divides into ant. and post. in front of obturator externis

ant. branch descends downwards n front of adductor longus and pectinius but behind adductor brevis

Question 16

what structures does ant. divison of bturatoe nerve supply?

Answer 16

1. pectinius
2. adductor longus
3. gracilis
4. adductor brevis( if post. doesn’t)
5. hip joint
6. subsartorial plexus and twig to femoral artery in adductor canal

Question 17

what is the path of post. division of obturator externis?

Answer 17

it divides in front of obturator externis
with posterior branch piercing through obturator externis
it travels in front of adductor magnus and behind adductor brevis

Question 18

which structures are supplied by post. divison of obturator nerve?

Answer 18

1. obturator externis
2. adductur magnus
3. adductor brevis ( if not by ant.)
4. in adductor canal is reduces to thinner genicular branch which pierces oblique popliteal ligament, and ends by supplying cruciate ligament and capsule of knee joint

Question 19

origin and root value of accessory obturator nerve.

Answer 19

ventral division of ant. primary rami of spinal nerves L3 L4

Question 20

Path of accessory obturator nerve.

Answer 20

medial to psoas major, crosses superior ramus of pubis, behind pectinius and terminates by dividing into three branches

Question 21

obturator nerve supplies which strucures?

Answer 21

1. pectinius
2. communicating branch of ant. branch of obturator nerve
3. hip joint

Question 22

obturator artery is a branch of?

Answer 22

internal illiac artery

Question 23

path of obturator artery

Answer 23

it acompanies obturator nerve ( just below the nerve) into the pelvis

it divides into ant./medial branch and post./lateral branch on upper surface of obturator foramen

they both encirlce the foramen and anastomoses with medial circumflex atrtery

posterior branch gives acetabular branch which suppiles fat of acetabular fossa and sends a twig to head of femuer (foveolar branch)

Question 24

medial circumflex artery is a branch of?

Answer 24

profunda femoris

Question 25

path of medial circumflex artery

Answer 25

is a part of profunda femoris
leaves femoral triangle by passing backwards
ends up dividing into ascending and transverse branch
