Lesson 18 (Part 1) Flashcards
What is the appearance of muscles?
Moderate echogenicity with echogenic striations
- seen within in long axis view
What can muscles be mistaken for in the female pelvis? (2)
- Ovaries
2. Masses
How many plans do you image the female pelvis? Why?
- 2 planes
- Because you could mistake something for a mass
- iliopsoas looks like a bullseye in short axis
Is the female pelvis intro or retroperitoneal?
Retroperitoneal
What happens to the female pelvis between birth and puberty?
Uterus descends gradually from the lower abdomen into the true pelvis
What is anterior to the uterus? (2)
- Pubic bone
2. Bladder
What is posterior to the uterus?
Rectum
What are the 3 major portions of the uterus?
- Fundus
- Body
- Cervix
Cornua
Area of the body where the tubes enter
- by the fallopian tubes
Where is the cornua located?
At the superior portion of the fundus of the uterus
Where is the body of the uterus located?
Area between Cervix and Cornua
Cervix
Slight narrowing between the body and the proximal cervix
What does the cervix open into?
The upper vagina
What is the cervix internally made up of? (2)
- Internal os
2. External os
What is at the distal end of the cervix space between the vagina? (3)
- Lateral fornix
- 2 of them - Anterior fornix
- Posterior fornix
What lies in the middle of the vagina?
A fibromuscular canal
Where does the fibromuscular canal run from?
The cervix to the external genitalia
Where does the cervix protrude into?
The proximal vagina
What lies posterior to the cervix?
The rectum
Uterus
Hollow, thick walled muscular organ
What are the 3 layers of the uterus?
- Perimentrium external
- Myometrium
- Endometrium
What layer makes up most of the uterus?
The myometrium
What are the layers of the myometrium?
- Inner layer
- Intermediate
- Outer
What is another word for the inner layer of the myometrium?
Subendometrial halo
What are the 2 layers of the endometrium?
- Superficial function layer
2. Deep basal layer
What does the superficial functional layer of the endometrium do?
Is the part that sloughs off each menses
What are the uterus’s ligaments? (6)
- Broad ligament
- paired - Cardinal
- paired - Uterosacral
- paired - Posterior
- Anterior
- Round
- paired
Broad ligaments
Double folds of parietal pertioneum
that suspends the uterus between these folds
Where is the broad ligament extend from?
Lateral aspect of uterus to the lateral pelvic walls
Cardinal ligaments
Lower extension of the broad ligament
Round ligament
Fibromuscular cords
Where does the round ligament extend from?
Extends from the upper outer angles of uterus through to the inguinal canal
What does the round ligament attach to?
The labia majora
Uterosacral ligaments
Fold like extensions of peritoneum
Where is the uterosacral ligament located?
Posterior uterus to the sacrum
- each side of the rectum
