Posterior Femoral Cutaneous Nerve

Front 1

Cutaneous nerve supply of posterior part of thigh is from

Back 1

poterior femoral cutaneous nerve

Front 2

origin of semimembranosus

Back 2

lateral part of ischial tuberosity

Front 3

insertion of semimembranosus

Back 3

horizontal concavity on back of medial condyle of tibia

Front 4

3 expansions from insertion of semimembranosus

Back 4

1. first expansion goes medial to the condyle deep to tibial collateral ligament of knee seperated by a bursa

2. 2nd expansion pass obliquely to lateral femoral condyle as oblique popliteal ligament

3. 3rd becomes strong fascia overlying popliteus reaching soleal line of tibia

Front 5

semtendinosus origin

Back 5

medial part of ischial tuberosity in common w long head of biceps

Front 6

semitendinosus insertion

Back 6

upper part of medial surface of tibial shaft

Front 7

biceps femoris origin

Back 7

long head: medial part of ischial tuberosity 2gether semitendinosus

short head: linea aspera whole length

upper part of lateral supracondylar line

Front 8

biceps femoris insertion

Back 8

head of fibula

Front 9

hamstring part of adductor magnus

ischial tiberosity

Front 10

hamstring part of adductor magnus inserts into

Back 10

adductor tubercule of femur w expansion into medial supracondylar line

Front 11

blood supply of hamstrings

Back 11

mostly from profunda femoris artery and perforating branches

upper part from inferior gluteal

lower part popliteal artery

they form anastamosis on back of thigh

Front 12

nerve supply of hamstrings

Back 12

sciatic

all except biceps short head is by tibial component (L5, S1)

short head by peroneal or fibular

Front 13

Front 14

when knee semiflexed bicep femoris is a

Back 14

lateral rotator of leg

Front 15

when knee is semi flexed semitend and semimembranosus

Back 15

are medial rotators of leg

Describe sciatic nerve division

Back 17

at apex of popliteal fossa, hands breadth above knee joint divide into tibial and common peroneal
