Title: The pelvis


1
The pelvis and perineum
2
  • Introduction
  • pelvis bony pelvis
  • pelvic walls
  • pelvic diaphragm
  • pelvic organs
  • blood vessels and nerves

3
  • The bony pelvis
  • --- hip bones,
  • --- sacrum
  • --- coccyx
  • --- their connections
  • (joints, ligaments
  • and pubic symphysis)

4
  • divisions
  • --- greater pelvis
  • --- lesser pelvis
  • oblique plane
  • Promontory of sacrum
  • Arcuate line
  • Pecten pubis
  • Pubic tubercle
  • Pubic crest
  • Superior border of
  • pubic symphysis

5
  • The pelvic walls
  • Post.--- sacrum, coccyx
  • piriformis
  • Ant.--- pubes, pubic symphysis
  • Lat.--- ilium,
  • body of the pubis, ischium
  • ligaments
  • obturator internus

6
  • The floor of pelvis
  • --- pelvic diaphragm
  • levator ani
  • coccygenus
  • deep fasciae
  • --- urogenital diaphragm
  • muscles
  • deep fasciae

7
  • The pelvic organs
  • ---The urinary bladder
  • ---The rectum
  • ---The pelvic part of ureter
  • ---The prostate
  • ---The pelvic part of ductus deferens
  • ---The seminal vesicle
  • ---The ejaculatory duct
  • ---The uterus
  • ---The ovaries
  • ---The uterine tubes
  • --- The vagina

8
?.The urinary bladder 1. Position, shape and
relatons It rests against pubis. When it
empty, is pyramid has a apex, body and fundus.
9
  • 2. The interior of the bladder
  • urinary trigone
  • ureteric orifices and
  • internal urethral
  • orifice
  • position
  • boundaries
  • clinical notes
  • to be susceptical
  • to tuberlosis and tumor.

10
---The rectum 1. Position and relations
11
2. The shape of the rectum --- 1216cm in
length --- 2 parts pelvic part
(ampulla of rectum)
anal canal --- 2 curves in sagittal plane
sacral flexure
perineal flexure --- 3 curves in coronal plane
12
  • 3. The internal features of the rectum
  • --- 3 transverse folds
  • --- 610 anal columns
  • --- anal valves
  • --- anal sinuses
  • --- dentate line
  • ectoderm and entoderm
  • there are differents in
  • epithelial lining, blood and
  • nerve supply and
  • lymphatic drainage
  • --- anal pecten

13
4.The blood vessels , lymphatic drainage and
nerves --- Arteries superior rectal a.
inferior rectal a.
anal a. --- veins internal
rectal venous plexus external rectal venous
plexus

15
  • --- lymphatic drainage
  • inferior mesenteric lymph nodes
  • internal iliac lymph nodes
  • superficial inguinal lymph nodes

16
  • --- The uterus
  • Position
  • between the urinary bladder and rectum
  • Anteflection
  • bent forward between the body
  • and neck
  • Anteversion
  • bent forward between the uterus
  • and vagina

17
2. relations ant.--- ant. Abdominal wall,
urinary bladder, intestine
post.--- rectouterine pouch,
rectum inf.--- vagina lat.--- uterine tube,
ovary, broad lig., blood vessels
sup.--- intestine
18
  • 3. The shape
  • pear-shaped
  • anterior and posterior surfaces
  • lateral borders
  • fundus,
  • body
  • neck supravaginal part
  • vaginal part
  • isthmus

19

20
  • 4. The ligaments
  • broad lig. of uterus
  • mesometrium
  • mesosalpinx
  • mesovarium suspensory lig. of ovary
  • cardinal lig. of uterus
  • round ligament of uterus
  • uterosacral lig.

21
  • 5. Blood vessels
  • The uterine artery---from the internal iliac a.
  • crosses above (or in front of) the ureter
    lateral to the
  • neck of uterus about 2cm

22
  • 6. The lymphatic drainage
  • Fundus and upper part --- lumbar lymph nodes
  • along the round lig. ---
  • superficial inguinal lymph
  • nodes
  • lower part and neck---
  • internal and external iliac
  • lymph nodes
  • 7. The nerves

23
  • Introduction
  • The Perineum
  • boundaries
  • divisions
  • anal region
  • urogenital regions in male and female

24
  • boundaries
  • --- same boundaries as the outlet of pelvis
  • inferior border of the pubic symphysis,
  • inferior rami of the pubes,
  • the rami of ischia
  • ischial tuberosities
  • sacrotuberous ligaments

25
2. divisions --- anal region anal canal ---
urogenital region urethra (male) urethra,
vagina (female)
26
3. Pelvic diaphragm --- levator ani ---
coccygeus --- superior fascia of pelvic
diaphragm --- inferior fascia of pelvic
diaphragm
27
  • The ischioanal fossa (ischiorectal fossa)
  • med.--- levator ani, sphincter ani externus,
    inferior fascia of pelvic
  • diaphragm
  • lat.--- ischial tuberosity, sacrotuberous
    lig., and the fascia of
  • obturator internus
