lateral 1/3 of inguinal ligament
inner rim of iliac crest
inner surface of costal cartilage of lower 6 ribs
lumbar fascia

23

26
Q

Psoas Major Origin

A

Sides of T12-L5 vertebrae
transverse processes of L1-L5

27
Q

Psoas Major Insertion

A

Lesser trochanter of the femur

28
Q

Psoas Major Action

A

Hip flexion

29
Q

Psoas Major Innervation

A

Anterior Rami of L1-L3

30
Q

Psoas Minor Origin

A

Sides of T12-L1 vertebrae

31
Q

Psoas Minor Insertion

A

pectineal line
iliopectineal eminence via iliopubic arch

32
Q

Psoas Minor Action

A

33
Q

Psoas Minor Innervation

A

Anterior Rami of L2-L3

34
Q

Iliopsoas

A

psoas major and minor

35
Q

Sacro-iliac Ligaments

A

Anterior Sacro-iliac Ligament
Interosseous iliac ligament
Posterior Sacro-iliac Ligament
Sacrotuberus Ligament
Sacrospinous Ligament

36
Q

Anterior Sacro-iliac Ligament

A

anterior part of the fibrous capsule

37
Q

Interosseous iliac ligament

A

primary involved in transferring weight of the upper body to the iliac
runs obliquely and out from sacrum

38
Q

Posterior Sacro-iliac Ligament

A

posterior external continuation of the interosseous iliac ligament
runs obliquely and out from sacrum
joined by fibers from the ilium and base of the coccyx to form the sacrotuberous ligament

39
Q

Sacrotuberous Ligament

A

passes from the posterior ilium and lateral sacrum and coccyx to the ischial tuberosities
transforms the sciatic notch of the pelvis into a large sciatic foramen
sacrum stabilization: prevent nutation

40
Q

Sacrospinous Ligament

A

goes from lateral sacrum and coccyx to the ischial spine
divides the sciatic foramen into greater and lesser
sacrum stabilization: prevent nutation

41
Q

Celiac Trunk

A

Originates from the aorta at T12
3 main branches
- left gastric artery
-common hepatic
-splenic artery

42
Q

Common Iliac Artery

A

originates from abdominal aorta
has a L & R
each artery divides into an internal and external

43
Q

Internal Iliac artery

A

main artery of the pelvis

44
Q

External iliac Artery

A

supplies blood to the legs and feet
branches to different names

45
Q

Common iliac Veins

A

originate from the internal iliac veins and external iliac veins
start at L4-L5
forms inferior vena cava

46
Q

Sacral Plexus

A

located on the posterior wall of the lesser pelvis
most nerves leave through the greater foramen
2 main nerves; sciatic and pudendal

47
Q

Sciatic Nerve

A

starts from sacral plexus L4-S3
largest nerve in the body
goes through greater foramen in most humans, inferior to the piriformis and deep to glute max

48
Q

Pudendal Nerve

A

goes to sex organs, S4/S3

49
Q

Piriformis Syndrome

A

sciatic nerve going through or above piriformis
can lead to compression or traction of nerve

50
Q

Superior Gluteal Nerve

A

part of sacral plexus
L4-S1
passes through the greater sciatic foramen and superior to piriformis
laterally between gluteus medius and minimus
supplies gluteal region

51
Q

Inferior Gluteal NErve

A

L5-S2
passes through greater sciatic foramen
inferior to piriformis but superficial to sciatic nerve
deep to inferior part of glute maximus
runs with inferior gluteal artery
supplies gluteal region
