Term
Hydrocele
Definition
accumulation of fluid within tunica vaginalis.

usually caused by infection or trauma

Penlight examination reveals a clear or transluscent scrotum, besides testes.
Term
Abdomen vs Testes(spermatic cord)
Fascia
Definition
Scarpas - Dartos
External ab oblique - Ex spermatic
Internal ab oblique - Cremaster
Transversalis fascia - Int spermatic
Peritonium - Tunica vaginalis.
Term
Inguinal Canal Borders
Definition
Anterior - aponeurosis of external oblique

Superior(roof) - internal oblique, transversus abdominis

Posterior: Transversalis fascia, conjoint tendon.

Floor: linguinal ligament, lacunar ligament
Term
Inguinal canal contents
Definition
Men: Spermatic cord + ilioinguinal, genital branch of genito-femoral nerve

Woman: Round Ligament, illioinguinal, genital branch of genito-femoral
Term
Thermoregulation of testes
Definition
Cremastic reflex - pulls testes in
(rubbing inner thigh sensory ilioinguinal)
(motor innervation from genital branch of genital femoral)

Dartos fascia contains smooth muscle fibers(corrugates skin, wrinkles)

Pampiniform plexus
Term
Indirect Hernias
Definition

most common; congenital; right side

 

Lateral to inferior epigastric vessels is indirect hernia. Indirect hernias go into inguinal canal

Term
Direct Hernia
Definition

Acquired inguinal hernia

15% bilateral; old men

passes MEDIAL to inf. epigastric vessels pushes through  through inguinal triangle(hesebachs) to enter inguinal canal

 

Medially: Rectus abdominus

Superior/Laterally: Inferior epigastric

Inferiorly: Inguinal ligament

Term
Femoral Ring Borders
Definition
Superior: inguinal ligament inferior: pectineal ligament lateral: fascia subdividing femoral sheath Medially: transveralis fascia Hernias protrude into ring. More common in women. Aberent obturator runs medially and may be damaged in hernia repair.
Term
Lateral Ventral or spigelian hernia
Definition

between rectus abdominus medially and semilunaris laaterally. Occur at or below arcuate line. Interpatietal hernia DON'T lie below cutaneous fat, it penetrates between muscles of abdomin

-no notable swelling, localized pain that increases w/ muscle tension & signs of obstruction

 

 

Term
Petit's hernia
Definition
Protrudes through lumbar triangle.

Triangle lies in posterolateral abdominal wall.

front: external oblique
behind: lat dorsi
below: iliac crest
Low chance of strangulation
Term
Lateral or Transverse cervical (cardinal or Machenrodt's) ligament
Definition
SUPPORTS the uterus, extends from cervix and vagina to pelvic wall and contains smooth m. fibers
at base of broad ligament

clinical significance: hysterectomy, close ureters, which can get damaged during ligation of the ligament
Term
Broad Ligament:
Definition
Double reflection of the peritoneum, draped over the round ligaments; contains ovaries, uterine tubes, and vasculature that serves them.
Term
Uterosacral Ligaments:
Definition
Provide minor cervical support.
Originate from the upper posterior cervix, travel around the rectum bilaterally, and fan out to attach to the 1st - 5th sacral vertebrae
Term
Cystocele
Definition
(prolapse of the bladder)- the front wall of the vagina (pubocervical fascia) prolapses. As a result, the bladder may prolapse into the vagina.
-urinary stress incontinence
Term
ALL EXTERNAL GENITALIA
Definition
Superficial inguinal lymph node (female)
Term
Glans clitoris
Definition
Deep Inguinal Lymph node
Term
Nerves and Micturition
Definition
Sympathetic- urine storage
-->Hypogastric plexus
Parasympathetic- voiding
--> motor pelvic splanchnic nerves S2-4
--> Pudendal n (S3, 4; somatic; external urethral sphincter)
Term
Erection and ejaculation
Definition
Point and shoot


Pelvic spanchnic nerves (S2-S4)


Somatic motor - Pudendal nerves (also provide afferent)


Inferior hypogastic plexus (sacral splanchnic nerves)
Term
Prostate tumors/cancers
Definition
Posterior lobe


metastasize to vertebrae -> brain


prostatic venous plexus -> sacral veins -> Vertebral venous plexus
Term
Begnign hypertrophy of prostate
Definition
median lobe


cause of urethral obstruction
Term
Lymph drainage of Testis and epididymis
Definition
Lumbar
Term
Lymph drainage of Scrotum
Definition
Superficial inguinal
Term
Penis Lymph drainage
Definition
skin-superficial inguinal


glans -deep inguinal


body and roots internal iliac
Term
Prostate gland and bladder
Definition
Internal iliac nodes
Term
Anal Canal
Definition
above pectinate -internal iliac


below pectinate-superficial inguinal
Term
Ovary and Uterine tubes Lymph drainage
Definition
Lumbar
Term
Uterus
Definition
lateral angle -Superficial inguinal


fundus and upper body - Lumbar


Lower body -External iliac
Term
Lymph drain Vagina
Definition
superior to hymen External&internal iliac


Inferior - Superficial
Term

Umbilical- superior vesical

Vaginal

Uterine

Pudendal (internal)

Rectal(middle)

Obturator

Gluteal (inferior)

Posterior: GIL

G: Gluteal (superior)

Iliolumbar

Lateral sacral

Term
BILATERAL LIGATION OF INTERNAL ILIAC ARTERY
Definition
1. median sacral artery & lateral sacral artery


2. superior rectal artery & middle/inferior rectal artery


3. ilio-lumbar artery & lumbar arteries,


4. Gluteal arteries & circumflex branches from deep femoral artery,

5. ovarian artery and uterine artery,

6. pubic branches of obturator arteries and pubic branches of inferior epigastric/external iliac arteries.
Term
INFERIOR VESICAL ARTERY in males
Definition
Is not found in females who have vaginal & uterine arteries in its place,


supplies the ductus deferens & prostate

comes off IIA or a common trunk with middle rectal,
Term
UTERINE ARTERY
Definition
deferential artery in males
--> Runs in the root of broad ligament until just superior to lateral vaginal fornix, lateral margin of uterus & transverse cervical ligament of Mackenrodt,
Term
What is the male homolog of the uterine artery and where does it come from and what does it supply?
Definition
Deferential artery as a branch of the inferior vesical artery. Supplies vas deferens
