Pelvic Anatomy Notes Flashcards
What is the adnexa?
The region including the fallopian tube and ovary.
What is the false pelvis?
The region of the pelvis located above the pelvic brim.
What are fimbriae ovarica?
The one fimbriae attached to the ovary.
What is the iliopectineal line?
An imaginary line from the superior border of the sacrum to the superior margin of the pubis symphysis that divides the true and false pelvis.
What is a ligament?
An extension of a double layer of peritoneum between visceral organs.
What is menarche?
The onset of menstrual cycles.
What is menopause?
The cessation of menses.
What is the mesovarian ligament?
The posterior portion of the peritoneum that attaches to the ovary.
What is mesosalpinx?
The upper fold of the broad ligament that drapes over the fallopian tube.
What is the perineum?
The surface region in both males and females between the pubic symphysis and the coccyx; area below the pelvic floor.
What is premenarche?
The time before the onset of menstrual cycles.
What is puberty?
The process of physical changes by which a child’s body becomes an adult body capable of reproduction.
What is the true pelvis?
The region of the pelvis found below the pelvic brim.
What is the pelvic anatomy?
The pelvis begins at the iliac crests and ends at the symphysis pubis, divided into the true and false pelvis by the iliopectineal line.
What is the true pelvis also known as?
Pelvic cavity or lesser pelvis.
What are the boundaries of the true pelvis?
Anterior boundary—symphysis pubis; posterior boundary—sacrum and coccyx; posterolateral wall—piriformis and coccygeus muscles; anterolateral wall—hip bone and obturator internus muscles; lateral boundaries—fused ilium and ischium.
What does the true pelvis contain? 4
- The female reproductive system
- Urinary bladder
- Distal ureters
- Bowel.
What is the false pelvis?
Located superior to the pelvic brim, contains loops of bowel.
What is the levator ani?
A group of muscles forming the pelvic floor that supports and positions the pelvic organs.
What is the sonographic appearance of the levator ani? 3
- Low-level
- Mildly curved linear echoes posterior to the vagina
- Hypoechoic compared with the normal uterus.
What is the iliopsoas Formed by? What kind of landmark does it serve as?
- Formed by the psoas major and iliacus muscles
- Serves as a lateral landmark of the true pelvis.
What is the sonographic appearance of the iliopsoas?
Low-level gray echoes with a distinct central hyperechoic focus.
What does the piriformis arise from? What is it a part of?
- Muscle arising from the anterior sacrum
- Part of the pelvic floor.
What is the sonographic appearance of the piriformis?
Low-level linear echoes, hypoechoic compared with the normal uterus.
