It is a pear shape muscular

organ.

1. Fundus.

2. Body.

3. Cervix.

7/30

it is the part of the uterus that

lies above the attachment of the

fallopian tubes.

It is the middle part that

extends from the cornu aboveto the isthmus below.


8/30

It is the narrow lower part of the

uterus that is marked from the body

by the isthmus.

The cavity of the cervix is a

fusiform canal that has 2 openings;one between cervix and body

(internal os) and the other one at its

lower end (external os).

The cervix is partially protrudes

into the vagina so it is divided into:

a) Vaginal part.

b) Supra-vaginal part.

The uterus is totally covered with

peritoneum except the anteriorsurface of the cervix.

Broad ligament.

Utero-verical pouch & recto-uterine

(Douglas) pouch.

It has a central position in the pelvis.

Anteverted anteflexed:

Anteversion; the anterior angle

between the uterus and the vagina

(90).

Anteflexion; the anterior angle

between the body and cervix (170)s.

Anterior; urinary bladder+ small intestine.

Posterior; sigmoid colon+ small intestine. On each side; attachment of the broad

ligament.

Anterior; urinary bladder.

Posterior; douglas pouch.

On each side; ureter + uterine artery.

Uterine support:

1. Pelvic floor muscles.

2. Anteverted anteflexed position

of uterus.

3. Uterine ligaments.

:1- Ligaments of the

body:

a- Round ligament of

uterus.

b- Ovarian ligament.

Ligaments of the

cervix:

a- Transverse

cervical

(Mackendrots)

ligament.


20/30

It is a double sheet of

peritoneum that stretches

between the side wall of the

uterus and the lateral pelvic

wall. It is quadrangular in shape

having 4 borders and 2

surfaces.

1. Mesovarium.

2. Mesosalpinx.

3. Mesometrium.

4. Suspensory ligament of the

ovary (infundibulo-pelvic)

ligament.


22/30

1. Uterine tubes.

2. Ligaments (ovarian ligament,

round ligament of uterus).

3.

Arteries (uterine artery,ovarian artery).

4. Parametrium (fatty tissue).

5. Embryological remnants.

Both are fibromuscular

ligaments.

The round ligament extend

between the uterus (in front of

fallopian tube) to labia majora.

The ovarian extend between the

uterus (behind the fallopian

tubes) and the ovary.

Lower part of body --------- externaliliac lymph nodes.

Cervix ------- external, internal iliac &

sacral lymph nodes.A small area around the cornu ---
