what are the fascia layers in the abdomen

Superficial
Camper's fascia (fatty layer)
Scarpa's fascia (membranous, deep layer)

Superficial


Camper's fascia (fatty layer)


Scarpa's fascia (membranous, deep layer)



define urinary extravasation

superficial fascia layer extends into penis and scrotum (Dartos fascia)
damage to the urethra can make urine/blood go into a 'pocket' surrounded by this fascia

superficial fascia layer extends into penis and scrotum (Dartos fascia)


damage to the urethra can make urine/blood go into a 'pocket' surrounded by this fascia

briefly describe abdominal lymph drainage

umbillicus is the line: above drains up (axillary lymph nodes), below drains down (superficial inguinal lymph nodes)

umbillicus is the line: above drains up (axillary lymph nodes), below drains down (superficial inguinal lymph nodes)

briefly describe venous drainage of the abdomen

femoral vein from leg, superficial epigastric vein, thoracoepigastric vein up to axillary vein

femoral vein from leg, superficial epigastric vein, thoracoepigastric vein up to axillary vein

what are the 3 muscle layers in the abdomen

superficial to deep:


external oblique


internal oblique


transversus abdominus

describe the external oblique

'hands in pockets' (superolateral to inferomedial)
lower 8 ribs
interdigitates with serratus anterior
attaches to aponeurosis (broad, flat tendon) 
attaches to anterior superior iliac spine, pubic tubercle and pubic crest (inguinal ligament)

'hands in pockets' (superolateral to inferomedial)


lower 8 ribs


interdigitates with serratus anterior


attaches to aponeurosis (broad, flat tendon)


attaches to anterior superior iliac spine, pubic tubercle and pubic crest (inguinal ligament)

define the linea alba

connection of left and right side aponeurosis at the midline

define the inguinal region

where the lower limb attaches to the torso

describe the internal oblique

fibers opposite direction to external 
lower rib attachment, anterior superior iliac spine, aponeurosis, linea alba
lower threads are underneath the inguinal ligament formed by external oblique, arch over the spermatic cord (or round ligament)

fibers opposite direction to external


lower rib attachment, anterior superior iliac spine, aponeurosis, linea alba


lower threads are underneath the inguinal ligament formed by external oblique, arch over the spermatic cord (or round ligament)

define the conjoint tendon

internal oblique attachment to pubic crest on both sides

describe transversus abdominus

transverse fibers
lower ribs, aponeurosis at center
anterior superior iliac spine
also under inguinal ligament, arch over spermatic cord (or round ligament) to help form conjoint tendon

transverse fibers


lower ribs, aponeurosis at center


anterior superior iliac spine


also under inguinal ligament, arch over spermatic cord (or round ligament) to help form conjoint tendon

where is the neurovascular plane located

between the internal oblique and transversus abdominus


extensions of intercostal nerves, T7-T11


subcostal nerves T12


anterior cutaneous branch of L1

describe rectus abdominis

extends from inferior edge of pectoralis major down to pubic crest
tendinous intersections through muscle (make 6 pack)
semilunar line


external oblique aponeurosis-- always in front
at ribs: deep is transversus and apon.
below ribs: ex front, tr...

extends from inferior edge of pectoralis major down to pubic crest


tendinous intersections through muscle (make 6 pack)


semilunar line




external oblique aponeurosis-- always in front


at ribs: deep is transversus and apon.


below ribs: ex front, transversus back and internal splits to both


lower: only thing behind is transversalis fascia


transversalis fascia-- always deep

define the arcuate line

where the deep layer of the rectus sheath stops and all that is left is transversalis fascia

where the deep layer of the rectus sheath stops and all that is left is transversalis fascia

describe the epigastric vessels

deep to rectus abdominus
superior: extensions of intercostals
inferior: branches of iliac vessels

deep to rectus abdominus


superior: extensions of intercostals


inferior: branches of iliac vessels

describe the parietal peritoneum

analagous to parietal pleura in lungs and parietal pericardium


in abdomen

what does the peritoneum form in inguinal region

tunica vaginalis (covering of testis)

what does the transversalis fascia form in inguinal region

deep inguinal ring


becomes internal spermatic fascia in testes

what does the transversus abdominus and internal oblique form in inguinal region

arching fibers, conjoint tendon


walls of inguinal canal




internal oblique forms cremaster muscle in testes

what does the aponeurosis of external oblique form in inguinal region

walls of inguinal canal


superficial inguinal ring




external spermatic fascia in testes

describe the components of the inguinal canal

external abdominal oblique aponeurosis from anterior superior iliac spine to pubic tubercle
pectineal ligament inferiorly
superficial inguinal ring (Ext. Ab. Oblique and pubic bone)
lateral crus/medial crus, intercrural fibers make ring

external abdominal oblique aponeurosis from anterior superior iliac spine to pubic tubercle


pectineal ligament inferiorly


superficial inguinal ring (Ext. Ab. Oblique and pubic bone)


lateral crus/medial crus, intercrural fibers make ring

describe the deep inguinal ring

point where 'flat' transversalis fascia becomes round internal spermatic fascia, makes a ring




hard to identify/see


can see the point where it is: internal oblique arches over spermatic cord

describe an indirect hernia

portion of bowel follows testicular route out of body, through deep ring and canal into scrotal sac

portion of bowel follows testicular route out of body, through deep ring and canal into scrotal sac

describe a direct hernia

through wall and canal but not through deep ring

through wall and canal but not through deep ring

describe the ilioinguinal nerve

L1 branch, follows spermatic cord to anterior testes

define the rectus sheath

aponeuroses of transversus, external and internal obliques


contains rectus abdominus
