pelvis

Question 1

psoas minor

Answer 1

from T12-L1 to the inguinal ligament

Question 2

psoas major P,D,A,NS

Answer 2

P- transverse processes of the lumbar vertebrae T12-L5 and IV discs between
D- lesser to hanger of femur
A- hip flexion
NS- anterior rami of lumbar nerves L1-L5

Question 3

iliacus P,D,A,NS

Answer 3

P- superior 2/3 of iliac fossa ala (wing) of sacrum and sacroiliac ligaments
D- lesser trochanter
A- hip flexion and stabilising hip
NS- femoral nerve

Question 4

pectineus

Answer 4

acducts and flexes hip
NS: femoral nerve and to a lesser degree the obturator nerve

Question 5

sartorious P,D,A,NS

Answer 5

P- anterior superior iliac spine
D- anterior aspect of the medial condyle of tibia
A - synergistic for hip flexion, lateral rotation and knee flexion
NS: femoral nerve

Question 6

Quadriceps 4 muscles (hip extensors)

Answer 6

• rectus femoris
• rectus medialus
• rectus lateralis
• vastus intermedius

Question 7

rectus femoris P,D,A,NS

Answer 7

P - anterior inferior iliac spine
D - quadriceps tendon (patella tendon- tibual tuberosity)
A- hip flexion and knee extension
NS : femoral nerve

Question 8

vastus medialis

Answer 8

P- intertrochanteric line and medial hip of linea aspera of femur (medial aspect of the vertical line - posterior aspect of femur)
D - quadriceps tendon - patella - patella tendon - tibial tuberosity
A - knee extension
NS - femoral nerve

Question 9

vastus lateralis

Answer 9

P- greater trochanter and lateral lip of linear aspera (vertical line ok posterior aspect of femur)
D - quadriceps tendon - patella - patella tendon - tibial tuberosity
A - knee extension
NS - femoral nerve

Question 10

vastus intermedius

Answer 10

p- anterior and lateral surfaces of the shaft of the femur
d - quadriceps tendon - patella tibial tuberosity
A - knee extension
NS: femoral nerve

Question 11

what does the femoral nerve supply

Answer 11

• iliacus
• pectineus
• sartorius
• rectus femoris
• vastus lateralis
• vastus medialis
• vastus intermedius
• articular genu

Question 12

what sensory branches does the femoral nerve supply

Answer 12

• anterior femoral cutaneous
• sphenoid nerve

Question 13

saphenous nerve

Answer 13

• largest branch of the femoral nerve
• travels down thigh behind sartorius in adductor canal* a tunnel in the middle 1/3 of the thigh
• crosses to medial side of knee to sartorius tendon
• becomes superficial between sartorius and gracious
• supplies skin medial side of leg below knee
