sacrum

Answer 4

triangular shaped bone near the end of the spine

Question 5

sacroiliac joint

Answer 5

joins the sacrum and the ilium to support the weight of the body

Question 6

ASIS

Answer 6

anterior superior iliac spine, attaches to inguinal ligament

Question 7

ischeal tuberosity

Answer 7

of the ischeum, sit on it

Question 8

acetabulum

Answer 8

socket of the ball and socket joint of the hip

Question 9

pubic tebercle

Answer 9

most posterior part of the pubis

Question 10

inguinal ligament

Answer 10

connects ASIS to pubic tubericle, boundary of lower abdomen and upper thigh

Question 11

aponeurosis of external oblique

Answer 11

lower edge forms the inguinal ligament

Question 12

obturator foramen

Answer 12

space between pubis and ischium

Question 13

linea aspera

Answer 13

attachment point of adductor muscles of femur, on posterior side

Question 14

condyles

Answer 14

knuckle like projections at the end of the shaft of the femur

Question 15

greater and lesser trochanter

Answer 15

protrusions on the femur

lesser - medially and inferiorly

Question 16

tibia, fibula

Answer 16

tibia, longer bears the weight

fibula = smaller, more posterior

Question 17

medial malleolus

Answer 17

medial part of the ankle, part of tibia

Question 18

lateral malleolus

Answer 18

lateral part of the ankle, part of the fibula

Question 19

intertrochanteric crest

Answer 19

connects greater and lesser trochanter of the femur

Question 20

great saphenous vein

Answer 20

runs from medial side up foot, up behind knee joint and continues medially to the hip, goes through fasica lata, empties into femoral vein

Question 21

anterior compartment of the thigh

Answer 21

quadricep muscles and sartorious, involved in flexing the thigh at the hip joint and extending the leg at the knee joint, supplied by femoral nerve

Question 22

medial compartment of the thigh

Answer 22

adductor group, bring thigh in towards midline, supplied by obturator nerve

Question 23

posterior compartment of the thigh

Answer 23

hamstring muscles, flexing the leg at the knee joint, supplied by tibial division of the sciatic nerve

Question 24

psoas major

Answer 24

originates from lateral part of lumbar vertebrae and runs to lower part of the abdomen

Question 25

Iliacus muscle

Answer 25

joins the psoas major, occupies ilieac fossa

Question 26

iliopsoas muscle

Answer 26

combination of psoas major and iliacus muscle, crosses hip joint from anterior aspect and inserts on lesser trochanter of the femur

Question 27

pectineus muscle

Answer 27

originates at superior ramus of the pubis and inserts on the femur right below the lesser trochanter, helps to flex the hip joint but can also adduct the hip (2 functions)

Question 28

four heads of the quadricep muscle

Answer 28

vastus medialis, vastus lateralis, vastus intermedius, and rectus femoris, only rectus crosses the hip joint, extends the leg at the knee joint

Question 29

rectus femoris

Answer 29

crosses both hip and knee joint, can flex the thigh at the hip joint and extend the leg at the knee joint

Question 30

sartorious

Answer 30

originates on ASIS, crosses thigh lateral to medial, inserts in tibia, can help to flex the thigh at the hip joint, abduct, and flex the leg at the knee joint

Question 31

How does the quadricep tendon get stabilized at the knee?

Answer 31

sits between the vastus medialis and vastus lateralus (problem = runners knee)

Question 32

iliotibial tract

Answer 32

thick part of the fasica lata, extends down lateral part of the thigh and crosses knee joint and inserts on the tibia, braces the knee for balance, pulled up by tensor fasica lata and gluteus maximus

Question 33

femoral sheath

Answer 33

surrounds femoral artery, vein and lymphatics (does not contain femoral nerve)

Question 34

branching of femoral artery

Answer 34

splits to deep and superficial femoral artery

Question 35

deep femoral artery

Answer 35

gives of branches that are the main supply of muscles of the thigh (medial/lateral femoral circumflex)

Question 36

superficial femoral artery

Answer 36

goes through gap in the abductor magnus and goes behind knee and becomes popliteal artery

Question 37

adductor longus

Answer 37

originates on pubic bone and inserts on linea aspera

Question 38

gracilis

Answer 38

originates at pubis, runs on medial side of thigh, crosses knee joint, inserts near sartorious tendon, adductor, but not a major player

Question 39

adductor brevis

Answer 39

more posterior, adducts at the hip

Question 40

adductor magnus

Answer 40

largest adductor muscle of the hip, has two nerves (horizontal = obturator, vertical = sciatic)

Question 41

nerve that supplies quadricep muscles

Answer 41

femoral nerve

Question 42

nerve that supplies adductor muscles

Answer 42

obturator nerve

Question 43

dorsal primary ramus

Answer 43

provide innervation to back muscles and sensations of the back, dont form plexus
