Unit 2 More on Genital Region
Urine Path
Male
Starting from preprostatic urethra
Prostatic Urethra
Membranous Urethra
Spongy/Penile Urethra
Navicular fossa
external urethral orifice
Landmarks: At the level of the bulbourethral gland
Landmarks: this is passing through the prostate, also where the ejaculatory duct from the seminal vesicle empties into
At the same level as the Seminal Vesicle
Female
Not as complex as males, bladder basically excretes the urine out of the urethra. Female urethra is very short.
Reproductive path
Male
Erection
Autonomic inervation
Smooth muscles relax and allow blood to fill sinuses
Somatic Innervation
Bulbospongiosus and ischiocavernous prevent outflow of the blood
Bloodflow to Penis
Buck's Fascia helps to orient the arteries
Deep to Buck's fascia, Deep Dorsal N, Dorsal A. Dorsal V. (Medial to Lateral)
Superficial to Buck's fascia: Superficial Dorsal V.
Corpus Cavernosum houses the deep artery to the penis.
Ejaculation
Testis
Epididymis
Ductus/Vas Deferens
Ejaculatory Duct
Secretions from Seminal Vesicle added
Prostatic Urethra
Secretions from Prostate added
Membranous Urethra

Female
Path from Ovary to Womb
Fimbria
Infundibulum
Ampulla
Isthmus
Body of Uterus
Implantation on Endometrium
where fertilization occurs
Layers of the Wall of the Uterus
Endometrium(wall of the uterus)
Myometrium,(Thickest layer also middle)
Perimetrium
Rectum+Anal Canal
Arteries
Internal Iliac A.
Middle Rectal A.
Pudendal A.
Inferior Rectal A.
Inferior Mesenteric A.
Superior Rectal A.
Remember me? :D i was the last branch of the IMA
Covers majority of the rectum
Aorta
Median Sacral A.
Vein
Middle Rectal Vein
Internal Iliac Vein(Caval)
Drains to the IVC
Inferior Rectal Vein
Superior Rectal Vein
Drains into Inferior Mesenteric Vein(Portal)
Is portal because it drains into splenic which drains into portal vein
Median Sacral Vein
Drains to the IVC
Pectinate Line
Above Pectinate Line is the Internal Venous Plexus
Below pectinate line is the External Venous plexus
Pectinate Line
Serves as a landmark, denoted by the renal lines. Closer to the opening of the rectum.
Below the Pectinate Line: Somatic sensory innerv, stratified squamous epithelium
Below means more external
Above the Pectinate Line:visceral sensory innerv, simple columnar epithelium
Above means more internal/deep
Pelvic Cavity
Bladder is Anterior to Rectum
Males
Prostate is attached below/inferiorly the vesicle/bladder
Seminal vesicle is posterior to the bladder and anterior to rectum, passes medially to ductus deferens
Ureter is between seminal vesicle and bladder/vesicle
Ductus/Vans Deferens is posterior to Seminal Vesicle
In Men, there is a rectovesicle pouch between bladder/vesicle and rectum.
Females
In Female, there is a rectouterine pouch
Uterus is between bladder and rectum, therefore female bladder/vesicle is significantly smaller than males.
Between Vesicle and Uterus, there is a Vesicouterine pouch
Shared Characteristics of the Bladder: Bladder has detrusor M.
Detrusor M. remains relaxed to allow urine to be stored, contracts to release urine
Within Bladder there is an imaginary triangle called trigone
Base of triangle is formed by the ureter orifices
Apex of trigone is the Internal urethral sphincters which are at the opening of the bladder
Pouches/recesses are important because they are areas where materials/liquids can remain and become infectious materials
Urogenital system AKA Internal Iliac artery and veins
Male
Internal Iliac Artery(Anterior Branch)
Umblicial A.
Superior Vesicle A., more than just one branch!!!
Artery of Ductus Deferens
Umblicial A. terminates as it becomes ligmentilazed
Inferior Vesicle A.
Obturator A. follows closely with Obturator N.
Middle Rectal A.
Internal Pudendal A.
Inferior Rectal A.
Inferior Gluteal A.
Female
Internal Iliac Artery(Anterior Branch)
Obturator a.
Umblical a.
Superior Vesicle A.
Uterine A.
Vaginal A.
Inferior Vesical a.
Middle Rectal A.
Internal Pudendal A.
Inferior Rectal A.
Inferior Gluteal A.
Uterine Positions
Retroversion
Anteflexion
Anteversion
Retroversion
Ligaments of Uterus
Attaching from the uterus to the ovary is the
Ligament of Ovary
Suspensory ligament of the ovary
Dual purpose, therefore it is not a solid ligament
Has vessels, brings ovarian artery and vein to ovary
Also helps to anchor ovary
Broad ligament of Uterus
Mesovarium
Engulfs the ovary
Mesosalpinx
engulfs the uterine tube
Mesometrium
Double layer covering whole thing
Remember that the ovaries can only be seen posteriorly
Round ligament of uterus
Internal Iliac Artery(Posterior Branch)
Lateral Sacral A.
Heads for the Sacrum, goes posterior very quickly and hugs sacrum
Superior Gluteal A.
Usually is between Lumbrosacral trunk and Ventral Rami of S1
Iliolumbar a.
Goes straight back up
