1

cutaneous nerves of anterior and medial thigh (7)

1. lateral cutaneous branch of subcostal nerve
2. femoral branches of gentiofemoral n.
3. iliolinguinal n.
4. lateral femoral cutaneous n.
5. anterior cutaneous branches of femoral n.
6. cutaneous branch of obturator n.
7. saphenous n.

2

muscles of the anterior thigh

iliopsoas
sartorius
quadriceps femoris
tensor fascia late Ilocated in anterior thigh but innervated by gluteal region)

3

iliopsoas muscle

function

innervation of three parts

chief flexor of thigh, stabilizes pelvis

iliacus: femoral nerve
psoas major: L1-L3 ventral rami
psoas minor: L1-L2 ventral rami

4

iliopectineal bursa is the common site for which injury

groin pulls

5

sartorius m.

most superficial, longest muscle

innervation: femoral nerve
function: flex, abduct, laterally rotate thigh, flex leg

6

common insertion for three muscles innervated by three separate nerves

pes anserinus

7

pes anserinus is composed of which three muscles

sartorius tendon
gracilis tendon
semitendinosus

8

bursa of pes anserinus

anserine bursa, common point of inflammation and injury from overuse

this is common in athletes

9

quadriceps foramis

innervation: femoral nerve (L2-L4)

function: vast extends leg, rectus extend leg and flexes thigh

10

Four muscles of quadriceps foramis

vastus lateralis
rectus femoris
vastus medialis
Vastus intermedialis

11

as the quadriceps femoris continues inferiorly, it becomes

ligamentum patella

12

adductors of the thigh can be found on which part

medially

13

muscles of the medial thigh (6)

pectineus
adductor brevis
gracilis
adductor hiatus
adductor longus
adductor magnus

14

pectineus muscle

attachments: to pecten line of pubis and pectineal line of femur

innervation: femoral nerve

functions: adduct and flex thigh

15

adductor longus

attachments: body of pubis and lines aspera

innervation: obturator nerve

function: adducts and flexes thigh

16

gracilis

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

17

adductor brevis

lies deep to pectinous and adductor longus

attachments: pubis body and inferior ramus, linea aspera

innervation: obturator nerve

functions: adducts and flexes thigh

18

groin pull

effects adductors of the thigh (medial)

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

19

adductor magnus

largest adductor

two parts:
1. adductor portion
2. hamstring portion

20

hamstring portion of adductor magnus

tibial division of sciatic nerve

adducts and extends thigh

21

adductor portion of adductor magnus

obturator nerve

adducts and flexes thigh

22

femoral triangle is bordered by

sartorius m
adductor longus m
inguinal ligament

23

floor border of femoral triangle, roof

pectins and iliopsoas muscle

roof: fascia lata

24

contents of femoral triangle (NAVEL)

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

25

femoral sheath allows the vessels

to glide smoothly deep to inguinal ligament during hip joint movement

surrounds the vessels and canal

26

three compartments of femoral sheath

divided by two vertical septa

1. lateral (femoral artery)
2. intermediate (femoral vein)
3. medial or femoral canal

NO FEMORAL NERVE

27

femoral canal

contains lymph vessels, connective tissue, and fat

allows femoral vein to expand during increased venous return

extends distally to saphenous opening

28

proximal opening of the femoral canal is AKA

femoral ring

small opening covers by parietal peritoneum

29

femoral hernia

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

30

two groups of lymph nodes in thigh

proximal and distal grow (horizontal and vertical)

passes deep to inguinal ligament and ran into external iliac lymph nodes
