Flashcards in Medial Compartment of the Thigh Deck (19):
1

gracilis attachments + what look like

inferior pubic rams below pubic symphysis

medial border of tibial tuberosity
(with tendons of sartorious and the semitendinosus)

long and thin

2

gracilis innervation

obtruator nerve

l2,3

3

gracilis actions

adduct and flex femur at hip joint

internally rotate leg at knee joint

4

pectineus attachments

pectin pubis

pectineal line and proximal line

5

pectineus ninnervation

femoral nerve and obtrutar nerve

l2-3

6

pectineus actions

adduct, externally rotate, and slightly flex femur at hip

stabilize pelvis in coronal and sagittal planes

7

adductor longus attachments

superior pubic rammus
and anterior side of pubic symphysis

medial lip of line aspera in middle third of femur

8

adductor longus innervation

obtrutar nerv
l2-4

9

adductor longus actions

adduct and flex femur at hip to 70 degrees
-past 80 degrees adductor longs extends femur at hip joint

stabilize pelvis in coronal and saggittal planes

10

adductor magnus attachments

inferior pubic ramus
ischial tuberoisty
ischial ramus

deep part-medial lip of line aspera of femur

superficial part-adductor tubercle of femur

11

adductor magnus innervation

deep-obturator l2-4

superficial-tibial l4

12

adductor magnus actions

adduct, extend, and slightly flex femur at hip joint

stabilize pelvis in coronal and sagittal plane

tendon active during internal rotati

13

subscap vs supraspin vs infraspin vs teres major/minor actions lol

subscap=internal rotation and extension

supra=abduction of arm

infra=extrnal rotation of arm

minor-external rotate and adduction

major internal rotation, adduction, extension of arm

14

where is adductor brevis muscle

deep to adductor longus

15

adductor brevis attachments

inferior pubic ramus

medial lip of line aspera in middle third of femur

16

adductor brevis innervation

obturator nerve l2,3

17

aductor brevis actions

adduct and flex femur when up to 70 degrees

stabilizes pelvis in coronal and sagittal planes

past 80 degrees of flexion, adductor braves acts to externd femur at hip jint

18

where is obturator externus

what does it do

deep to pectineus

covers external aspect of obturator foramen

19

what does obturator nerve do

where does it pass

where is anterior branch

innervates muscles of medial compartment

passes from pelvis to medial aspect of thigh via obturator canal
-goes under adductor longus

on anterior surface of adductor brevis muscle
