Answer 5

most superficial, longest muscle

innervation: femoral nerve

common insertion for three muscles innervated by three separate nerves

Answer 6

pes anserinus

Question 7

pes anserinus is composed of which three muscles

Answer 7

sartorius tendon
gracilis tendon
semitendinosus

Question 8

bursa of pes anserinus

Answer 8

anserine bursa, common point of inflammation and injury from overuse

this is common in athletes

Question 9

quadriceps foramis

Answer 9

innervation: femoral nerve (L2-L4)
function: vast extends leg, rectus extend leg and flexes thigh

Question 10

Four muscles of quadriceps foramis

Answer 10

vastus lateralis
rectus femoris
vastus medialis
Vastus intermedialis

Question 11

as the quadriceps femoris continues inferiorly, it becomes

Answer 11

ligamentum patella

Question 12

adductors of the thigh can be found on which part

Answer 12

medially

Question 13

muscles of the medial thigh (6)

Answer 13

pectineus 
adductor brevis
gracilis
adductor hiatus 
adductor longus 
adductor magnus

Question 14

pectineus muscle

Answer 14

attachments: to pecten line of pubis and pectineal line of femur
innervation: femoral nerve
functions: adduct and flex thigh

Question 15

adductor longus

Answer 15

attachments: body of pubis and lines aspera
innervation: obturator nerve
function: adducts and flexes thigh

Question 16

gracilis

Answer 16

long strap like (only adductor to cross knee)

attachment: pubis and body of inferior ramus, superior medial surface
innervation: obturator nerve
functions: adduct thigh, flex and medially rotate leg

Question 17

adductor brevis

Answer 17

lies deep to pectinous and adductor longus

attachments: pubis body and inferior ramus, linea aspera
innervation: obturator nerve
functions: adducts and flexes thigh

Question 18

groin pull

Answer 18

effects adductors of the thigh (medial)

caused by strain, stretching, and tearing of proximal attachments of thigh adductors and flexor muscles

Question 19

adductor magnus

Answer 19

largest adductor

two parts:

1. adductor portion
2. hamstring portion

Question 20

hamstring portion of adductor magnus

Answer 20

tibial division of sciatic nerve

adducts and extends thigh

Question 21

adductor portion of adductor magnus

Answer 21

obturator nerve

adducts and flexes thigh

Question 22

femoral triangle is bordered by

Answer 22

sartorius m
adductor longus m
inguinal ligament

Question 23

floor border of femoral triangle, roof

Answer 23

pectins and iliopsoas muscle

roof: fascia lata

Question 24

contents of femoral triangle (NAVEL)

Answer 24

femoral n. (+branches)
femoral artery (+ branches) 
femoral vein (+tributaries)
femoral canal (empty space with lymph nodes)

Question 25

femoral sheath allows the vessels

Answer 25

to glide smoothly deep to inguinal ligament during hip joint movement surrounds the vessels and canal

Question 26

three compartments of femoral sheath

Answer 26

divided by two vertical septa 1. lateral (femoral artery) 2. intermediate (femoral vein) 3. medial or femoral canal NO FEMORAL NERVE

Question 27

femoral canal

Answer 27

contains lymph vessels, connective tissue, and fat allows femoral vein to expand during increased venous return extends distally to saphenous opening

Question 28

proximal opening of the femoral canal is AKA

Answer 28

femoral ring small opening covers by parietal peritoneum

Question 29

femoral hernia

Answer 29

occurs where the small intestine protrudes into femoral canal through femoral ring

Question 30

two groups of lymph nodes in thigh

Answer 30

proximal and distal grow (horizontal and vertical) passes deep to inguinal ligament and ran into external iliac lymph nodes

Question 31

deep inguinal lymph nodes

Answer 31

1-3 nodes along medial side of femoral vein inside femoral canal of femoral sheath drain external iliac lymph nodes

Question 32

femoral nerve

Answer 32

largest branch of lumbar plexus enters thigh lateral to inguinal ligament, femoral vessels

Question 33

what is supplied by femoral nerve

Answer 33

anterior thigh muscles, hip and knee joints iliac sartorius quadriceps femoris pectinous

Question 34

meralgia parenthetic

Answer 34

compression of lateral femoral cutaneous nerve as it passes under inguinal ligament and causes pain along lateral thigh caused by anterior hip dislocation

Question 35

saphenous nerve

Answer 35

cutaneous branch supplies skin of anterior and medial knee and leg, medial foot

Question 36

femoral artery

Answer 36

chief arterial supply of lower limb gives rise to descending genicular artery (articular and saphenous branches)
