23
Q

Lacunar Ligament

A

between pubic rami and inguinal ligament to attach them

24
Q

Pectineal Ligament

A

Fibers from lacunar lig —-> pubic pubic

25
Femoral canal (subinguinal space)
lateral to lacunar lig and the superficial inguinal ring
26
Deep Ring
entrence to the inguinal canal (transversalis fascia) vas deferens and gonadal vessels/ nerves pass = males round ligament pass= females
27
Genitofemoral Nerve L1, L2
Cremasteric branch motor | medial thigh and scrotum/labia sensory
28
where do gonads from
T10
29
gonads are connected to what future thing
future scrotal swellings by the gubernaculum
30
how does the gonads descend
descends by an out-pocketing (peritoneal cavity)= process vaginalis down to the future scrotum ,leaving behind the Suspensory Ligament
31
when connection to perironeum is closed for the gonads what is the remains of the process vaginalis around the testes
TUNICA VAGINALIS
32
which tree muscles help develop the spermatic cord as the gonads descend
Transversalis fascia - internal spermatic fascia IO- cremasteric muscle EO- external spermatic fascia
33
Processus vaginalis
evagination of the peritoneal cavity | communication closes around 1st year postnatally
34
Cryptorchid testis
undescended testis = increase risk of testicular cancer
35
5 contents in the spermatic cord
1. Vas Deferens (ductus deferens) 2. Testicular A 3. Testicular V (pampiniform plexus) 4. Gonadal N 5. Gonadal Lymph
36
persistent processus vaginalis
failure to close connection between the tunica vaginalis and abd.
37
Hydrocele
peritoneal fluid accumulated in the tunica vaginalis (babies, if in adults= inflammation due to scrotum testies or epididymis injury) Dx with :transillumination -> shine light through
38
Hematocele
accumulation of blood in the tunica vaginalis
39
Ovarian Descent
when descending the gubernaculum gets attached to the uterus
40
What does gubernaculum form in females
ovarian lig and round lig of uterus
41
how does the round lig of uterus travel
enters the deep ring and travels through it exiting the superficial ring and ---> attaches to the labial swellings
42
3 contents of the Female inguinal canal
1. Round lig of uterus 2. Iliolinguinal N 3. Genitofemoral N
43
scrotum is related to what in the female
Labia
44
where do veins drain into from the scrotum
superficial inguinal node and ---> iliac and lumbar lymph nodes
45
where do veins drain into form the testes
lumbar and pre-aortic lymph nodes
46
inferior epigastric is part of the
anterior abd
47
Median umbilical fold
from the obliterated urachus (paraumbilical veins)
48
Medial umbilical fold
from obliterated umbilical arteries
49
Lateral umbilical fold
from inferior epigastric A.
50
Direct Hernia
Happens inferior to conjoint tendon and umbilical tendons = lateral umbilical fold Medial to inferior epigastric A peritoneum and transversalis fascia go through the superficial ring next to the spermatic cord
51
Indirect Hernia
the abd fascia and peritoneum enters the deep ring and exits the superficial ring WITHIN the spermatic cord
52
Femoral Hernia
abd fascia and peritoneum exit below the superficial ring and below the inguinal lig through the femoral canal.
53
Hesselbach's Triangle
above and medial to the inguinal canal (superficial ring) on the EO
54
Inguinal canal is made of
inguinal lig | Lateral border of the rectus abd.
55
Iliopubic tract
reinforces the floor of the inguinal canal by the transversalis fascia posterior to the inguinal lig.
