25
Arteries between the TA and the IO in the anterolateral abdonimal wall
Posterior intercostal arteries and subcostal arteries
26
On posterior surface of RA wthin the rectus sheath, also supplies the RA
Superior epigastric artery
27
Posterior surface of the RA and anastamoses with superior epigasteric A.
Inferior epigastric artery
28
Forms a communication b/t the axillary and femoral veins
Thoracoepigastric vein
29
Superficial lymphatic drainage superior to umbillicus
Drains to axillary
30
Superficial lymphatic drainage inferior to umbillicus
Drains to superficial inguinal nodes
31
Runs from the Apex of the bladder to the umbilicus
MediaN umbilical fold (Singular!!)
32
Remnants of the obliterated umbilical arteries passing from the internal iliac ateries
MediaL umbilical folds (Paired!!)
33
Contains the inferior epigastric artery
Lateral umbilical fold
34
Space between the inguinal ligament, lateral umbilical fold, and lateral margin of RA
Inguinal triangle (Hesselbach's)
35
Remnant of the umbilical vein, from umbilicus to the liver
Ligamentum teres
36
How is the inguinal ligament "formed"?
The inferior free mragin of the EO aponeurosis is turned/rolled under
37
Attachments of the inguinal ligament
ASIS to the pubic tubercle
38
Oblique passage thru inferior part of the anterior abd wall b/t the deep/superficial inguinal rings
Inguinal canal
39
3 openings of the inguinal canal
1) circular opening in transversalis fascia (deep ring) 2) arch of IO & TA superior to the inguinal ligament 3) oblong opening in the EOA (superficial ring)
40
Which ring is lateral to inferior epigastric vessels?
Deep inguinal ring, 1/2 way b/t ASIS and pubic tubercle
41
Formed by the EOA and attaches to the pubis symphsis
Medial Crus
42
Formed by the inguinal ligament and attaches to the pubic tubercle
Lateral crus
43
Posterior barrier of the superficial inguinal ring
Conjoint tendon of the IO and TA
44
Floor of the inguinal canal
Lacunar ligament (inguinal ligament attaching to the pubis) and pectineal ligament (cont of the lacunar ligament, attching to the pectineal line of the pubis)
45
Anterior wall of inguinal canal
EO aponeurosis, IO muscle fibers, is strongest anterior to the deep ring
46
Roof of the inguinal canal
Arching fibers of IO/TA
47
Posterior wall of inguinal canal
Transversalis fascia, conjoint tendon, strongest portion is posterior to superficial ring
48
Contents of inguinal canal in females
Round ligament of uterus, ilioinguinal nerve, genital branch of genitofemoral nerve
49
Contents of inguinal canal in males
Spermatic cord and coverings, ilioinguinal nerve, genital branch of genitofemoral nerve
50
Coverings of the spermatic cord
External spermatic fascia (EO), Cremasteric fascia/muscle (IO), internal spermatic fascia (TF)
51
Divides the cavities of the scrotum
Scrotal septum
52
What fascia is the dartos fascia cont w/?
Scarpa's and Colles'
53
Attaches the testis
Scrotal ligament
54
Parts of the epididymis
Head, body, tail
55
What is the tail of the epididymis cont w/?
Ducuts deferens
56
Arterial branches off of the aorta that come off just below the renal arteries
Testicular arteries
57
Testes lymphatic drainage
Para-aortis lymph nodes
58
Scrotal lymphatic drainage
Superficial inguinal nodes
59
Where do tests develop?
Extraperitoneal space in upper lumbar levels
60
Connects the testis to the scrotum
Gubernaculum
61
What evaginates to form the processus vaginalis?
parietal peritoneum
62
Formation of internal spermatic fascia
Testis descend thru the deep inguinal ring, pushing the TF to become to ISF
63
Formation of the cremasteric fascia/muscle
Testis descends thru the IO muscle, forming the CF/M
64
Formation of the external spermatic fascia
When testis reach the superficial ring, pushes the EO aponeurosis to form the ESF
65
Incomplete descent of the testis
cryptochidism
66
3 common sites of hernias
Umbilical, epigastric, spigelian
67
Most common form of inguinal hernias
Indirect, and is usually congenital, more common on the right
68
Site of initial herniation in indirect inguinal hernias
At deep inguinal ring, lateral to inferior epigastric vessel, superior to the level of the pubic tubercle
69
Direct inguinal hernia
Weakening of the conjoint tendon along the posterior wall of the inguinal canal allos for a bulging of abd contents
70
Sight of initial hernitaion in direct inguinal herniation
medial to inferior epigastric vessels, superior to pubic tubercle
71
Femoral herniations
More common in women, abd contents descend thru the femoral canal
72
Site of initial hernitation in femoral herniations
At femoral ring, then buldges inferior to the level of the pubic tubercle/inguinal ligament
