Inguinal Region (Abdomen) Flashcards
where do structures exist and enter the abdominal cavity
the inguinal area
75% of abdominal hernias happens in
inguinal area
86% of inguinal hernia occur in
males, because of the passage of the spermatic cord through inguinal canal
male gonads travel through what to get from the abdomen to the perinuem
the inguinal canal
the ingiunal ligament and illopubic tract is the lowest portion of what
our external oblique
last portion of the external oblique aponeruosis
lacunar ligament forms what
the medial boundary of the subinguinal space
pectineal ligament of Cooper
most lateral of the fibers and it runs along pecten pubis
the thickened inferior margin of the transversalis fascia that appears as a fibrous band and runs parellel to the inguinal ligament is the
iliopubic tract
iliopubic tract can be viewed?
posteriorly
the inguinal lig and iliopubic tract span an area of innate weakness in the groin area called
myopectineal orifice
the myopectineal orifice is the sight of what
groin hernias
femoral hernia is more common in
female ( due to size of pelvis
the dragging process of gonads occurs where
inguinal canal ( formed for dragging)
what lies parallel and superior to the inguinal ligament
the inguinal canal
the round lig ( women) and spermatic cord ( males) is main occupant of
inguinal canal
the inguinal canal also has
blood and lymphatic vessels
gubernaculum (male)
a fibrous cord that connects the primordial testies to the anterolateral abdominal wall
all blood vessels for testes and ovaries come from
the posterior side of lumbar area (dragging area)- they are not the structure of pelvis
testes are in pelvis when
12th week
testes are close to inguinal ring when
28th week ( 7 months)
testies begin to pass through inguinal canal when
28th week
how long does it take for testes to pass through inguinal canal
3 days
as the testis, ductus deference and its vessels/nerves descend they are ensheathed in what
musculofascial extensions from the anteriorlateral abdomen wall
( making adult scrotum)
the stalk of the process vaginalis normally degenerates but the distal part of it forms what
tunica vaginalis (serous sheath of the testis and epididymus)
where the inguinal canal is developed in males the what is developed in women
the labium majorus
ovaries cannot go where due to connection?
inguinal area
the female gubernaculum is what
a fibrous cord that connects the ovary and primordial for uterus and forms the labium majorus
ovary ligament is where
between oavry and uterus
round ligament of the uterus is where
between uterus and labium majorus
ovaries do not descend to the inguinal region why
because of the ovarian ligament
what does go to the inguinal area in women connecting to the labium majora?
the round ligament
the superficial inguinal rings in infants lie where
almost directly anterior to the deep inguinal rings
the testes are outside of the body why
because the sperm cannot be produce inside of the body due to the temperature
inguinal canals are narrower in who
women
inguinal canals i children are what
shorter then they are in adults
the deep inguinal ring
the internal entrance of the inguninal canal
sueprfical inguinal ring
the exit by which the spermatic cord in males and round lig in women comes out of inguinal canal
lateral crus attaches to where
pubic tubercal
medial crus attaches where
the pubic crest
medial and lateral crus do what
are the margins of the superfical ring
the medial and lateral crus do what
keep the aponeruosis from splitting
the inguinal canals have two what? and what else
two walls and a roof and floor ( like a tunnel)
posterior wall of inguinal canal is formed by
transversalis fascia
anterior wall of inguinal canal is mainly formed by?
external oblique
roof of inguinal canal is formed by
transversalis fascia
aponeruosis of internal and transverse abdominis
medial crus of external oblique
floor is mostly formed by
inguinal ligament
the deep and superficial inguinal rings do not do what in adults
overlap, because they are oblique
pressure on the inguinal canal will cause
it to collapse because it is oblique
superifical inguinal ring is the final what
exist of inguinal canal
what makes the roof of the canal descend and also constricts the canal
contraction of the external oblique muscles
which ligament bypasses the pubic tubercle and fan upward
reflected inguinal lig
the inguinal lig and iliopubic tract span an area of innate weakness in the body wall of the groin called?
the myopectineal orifice
where is the site of groin hernias
myopectineal orifice
when is the inguinal canal formed
in relation to the decent of the testes in fetal developmetn
how long is the inguinal canal in adults
4cm long
main occupant of inguinal canal
spermatacord/ round lig
where is blood, lymphatic vessels and ilioinguinal never in both sexes located
inguinal canal
male gubernaculum
is the fibrous cord that connects the future testes to the anteriolateral abdominal wall
process vaginalis
is the dragging of he muscular and fascia layers before it enters the scrotum
