Fat and fascia
Perinephric fat enclosed within renal fascia
Fat found outside renal fascia
Paranephric
Blood supply
Renal artery from abdominal aorta
Renal vein from IVC
Ureter divisions
Abdominal
Pelvic
Intramural
Urinary bladder surfaces
Superior
Inferolateral
Posterior
Bladder angles
Apex
Posterolateral
Neck of the bladder
Bladder attached structures
Median umbilical ligament (superior)
Ureter (inferolateral)
Urethra (neck of bladder)
Female urethra
From bladder to vestibule
Opens between:
1. Clitoris (anterior)
2. Vaginal opening (posterior)
Male urethra divisions
Prostatic
Membranous
Spongy
Parts of uterus
Fundus (largest)
Body (middle)
Isthmus (lower)
Cervix (narrowed end)
Uterine cavity (triangular cavity)
Uterus relations
Anterior- superior surface of bladder
-uterine pouch
Posterior- rectum
-pouch of douglas (recto uterine pouch)
Where is the vagina found
Pelvis
Right angle to uterus
Mucosal folds found on vagina
Ruggae
Vagina relations
A- bladder and urethra
P- rectum,anal canal, recterouterine pouch
L- pelvic diaphragm
S- uterus
1st Part of vulva
Mons pubis (covered by hair and skin)
Overlies the pubic symphysis
2nd part of vulva
Labia majora (2 THICK folds)
Extend from pubic symphysis to perineal body
3rd part of vulva
Libia minora (2 THIN folds medial to libia majora)
NO FAT
VASCULARIZED
FUSE AT CLITE
4th part of vulva
Clitoris (homologue of penis)
What does the uterus form
Birth canal with the vagina
What covers the uterus
Peritoneum
Where does the uterus lie
Between bladder and rectum
Which part of the male urethra form the reproductive system
Prostatic and membranous
Ductus derefens
Thick
From tail of epididymis
Terminates in ejaculatory duct(AMPULLA)
Course of ductus deee deference
Ascends from testes
Enters inguinal canal
Pierces through abdomen
Curves laterally
Descends into pelvis
RETROPERITONEAL
Turns medially
Posterior to bladder
Joins seminal vesicles
Form ejaculatory duct
3 membranous layers surrounding testes
Tunica vaginalis(outer)
Tunica albuginea (middle)
Tunica vasculosa (inner)
Tunica vaginal
OUTER LAYER
Closed sac of serous membrane
Formed by abdominal peritoneum
Has parietal and visceral layers
FILLED WITH SEROUS FLUID IN BETWEEN
Tunica albuginea
MIDDLE LAYER forming firm,white covering
FORMS SEPTA , dividing testes into lobes
Tunica vasculosa
INNER THIN LAYER
Contains blood vessel plexus
Seminiferous tubules
Found on each lobe
Produce sperms
Where do seminiferous tubules terminate the
At the rete testes
Origin of efferent ducts
Where do they leave testes
Where do they ascend into
Originate from latter
Leave at mediastinum
Ascend into first part of the epididymis (caput)
Epididymis
Connects testes and vas deferens
Head: caput epididymis
Tail: cauda epididymis
Spermatic cord
3 arteries, 3 nerves and 3 layers, 3 structures
Spermatic cord layers (fascia)
Outer spermatic
Cremasteric
Inner spermatic
Spermatic cord arteries
Testicular
Cremasteric
Artery to ductus deference
Nerves of spermatic cord
Genital branch of genitofemoral
Ilioinguinal
Sympathetic fibres
Other structures of spermatic cord
Pampiniform venous plexus
Lymphatics
Ductus deference
Penis
Composed of root and body
Root lies in perineum
Busy is mobile and covered with skin
Erectile tissue cylinders of penis
2 dorsal corpus carvenosa
1 ventral corpus spongiosum
The site of attachment with urogenital diaphragm
Bulb
Where does Penis (root) lie?
Perineum (space between anus and scrotum)
What binds the 3 erectile tissue cylinders of penis
Tunica albuginea
What is the head of the penis
Glans
What makes the glans (head of the penis)
Corpus spongiosum
Site of attachment of penis with Urogenital diaphragm
Bulb
