Thigh region

Question 1

What does the fascia lata/iliotibial tract do in the leg

Answer 1

-it is fascia around the thigh that keeps fluid in place to prevent edema from the affects of gravity on the legs
-iliotibial tract (IT band) is a thickening of the fascia late and the great saphenous even passes through an opening in this

Question 2

Posterior compartment of the thigh
-muscles
- nerve supply

Answer 2

-Muscles
1. Hamstrings
-Nerve supply:
1. divisions of the sciatic nerve

Question 3

What muscles make up the hamstrings

Answer 3

1. Semimembranosus (medial)
2. Semitendinosus
3. Biceps femoris
   -short head
   -long head

Question 4

Pes anserinus

Answer 4

-conjoined tendons of three muscles:
1. sartorius
2. Gracilis
3. SemTendinosus

Question 5

Lumbosacral plexus anterior divsion nerves and nerve roots

Answer 5

1. pedundal nerve S2-S4
2. Posterior Femoral Cutaneous (S1-S3)
3. nerve to superior gemellus and obturator internus (L5-S2)
4. nerve to inferior gemellus and quadratus femoris L4-S1
5. tibial nerve L4-S3

Question 6

Lumbosacral plexus posterior divison nerves and nerve roots

Answer 6

1. perforatin cutaneous nerve (S2-S3)
2. Nerve to piriformis muscle S1-S2
3. Superior gluteal nerve L4-S1
4. inferior gluteal nerve L5-S2
5. common fibular (peroneal) nerve L4-S2

Question 7

Dermatomes of the LE

Answer 7

L1: Anterior hip
L2: superior anterior lateral thigh and superior to glutes
L3: inferior anterior medial thigh
L4: medial leg-big toe
L5: lateral leg and toes 2-4
S1: lateral malleoli and 5th toe
S2: posterior superior leg to thigh
S3: middle gluteal reiogn
S4: inner gluteal region

Question 8

cutaneous innervation of the LE
1. femoral nerve
2. superior and inferior gluteal nerves
3. obturator
4. sciatic
5. common fibular (superior branch and inferior branch)

Answer 8

• femoral nerve: anterior compartment of thigh
• superior and inferior gluteal nerves posterior superior LE (around glutes)
• obturator: medial compartment of thigh
• sciatic nerve: posterior compartment of thigh, leg, and sloe of foot
• common fibular nerve: near head of fibular
• superficial branch: (common fibular nerve) : lateral compartment of leg
• deep branch anterior compartment of leg
