23
Q

lymph of diaphragm

A

superior diaphragmatic nodes -> mediastinal nodes

inferior diaphragmatic vessels -> superior diaphragmatic and or lumbar nodes

24
Q

psoas major

A

bodies and transverse processes of TV12-LV5 and IV discs
lesser trochanter
flexion of thigh, flexion of vertebral column
ventral rami of L1-3

25
psoas minor
bodies of TV12-LV1 and IV discs iliopectineal eminence flex VC ventral rami of L1
26
iliacus
iliac fossa lesser trochanter flex thigh femoral
27
quadratus lumborum
iliac crest and iliolumbar lig 12th rib, transverse processes of lumbar vertebrae extends/SB vc, inspiration ventral rami T12-L4
28
positive psoas sign right
``` kidneys ureters cecum appendix ascending colon sacroiliac joint ```
29
positive psoas sign left

30
lumbar plexus sensory
anterolateral abdominal wall, inguinal region, ant scrotum/labia majora, gluteal region, perineum, LL
31
lumbar plexus motor
anterolateral abdominal wall, posterior abdominal wall, LL
32
iliohypogastric
L1 forms posterior to medial arcuate lig, arches over quadratus lumborum, pierces transversus abdominis to run btwn it and IAO near ASIS pierces IAO to run btwn it and EAO ends by providing suprapubic cutaneous brr
33
ilioinguinal
L1 II to iliohypogastric, but inferior near ASIS pierces IAO to run btwn it and EAO enters inguinal canal and provides ant scrotal/labial brr
34
femoral
L2-4 laterla to psoas major, runs across iliacus to pass deep to inguinal lig LL
35
lateral cutaneous nerve of thigh
L2-3 lateral to psoas major, corses along iliacus towards ASIS, passes under inguinal lig near ASIS to enter thigh provides sensory to lat thigh
36
genitofemoral
L1-2 pierces psoas major genital br enters inguinal canal to innervate cremaster femoral br passes under inguinal lig to provide cutaneous innervation to ant thigh
37
obturator
L2-4 medial to psoas major, runs along lateral pelvic wall, exits pelvis via obturator canal to enter medial thigh provides sensory and motor innervation to medial thigh
38
lumbosacral trunk
L4-5 descends over pelvic brim to join sacral plexus
39
accessory obturator
