◉ *Anatomy:*
Ischial Spines.
Answer: Prominences that arise near the junction of the ilium and
ischium and jut into the pelvic cavity; used as a reference point
during labor to evaluate the descent of the fetal head into the birth
canal.
◉ *Anatomy:*
Symphysis Pubis.
Answer: Where the 2 ossa coxae meet
◉ *Anatomy:*
Linea terminalis.
Answer: Imaginary line that separates the true pelvis from the false
pelvis
,◉ *Anatomy:*
Ischial Tuberosities.
Answer: Strongest part of hip bone, "sit bones"
◉ *Anatomy:*
Pubic arch.
Answer: Inverted V-shaped arch inferior to pubic symphysis. Over
90° in females, and about 60° in males.
◉ What are the three divisions of the pelvis?.
Answer: Inlet, midpelvis and outlet
◉ Bordered by the linea terminalis and upper third of sacrum:.
Answer: Inlet
◉ Bordered by upper third of sacrum and ischial spines.
Answer: mid-pelvis
◉ Bordered by ischial spines, coccyx and ischial tuberosities.
Answer: Outlet
,◉ What are the *four* types of pelvis'?.
Answer: Gynecoid
Android
Anthropoid
Platypelloid
◉ Gynecoid Pelvis.
Answer: Categorized as a typical female pelvis (although only about
half of all women have this type of pelvis); the rounded shape of the
gynecoid inlet allows the fetus room to negotiate the dimensions of
the bony passageway; *Ideal for delivery*
◉ Android Pelvis.
Answer: The typical male pelvis; in the woman, the heart shape of
the android pelvis is not favorable to a vaginal delivery
◉ Anthropoid Pelvis.
Answer: Pelvic that is oval shaped, with a wider anteroposterior
diameter
◉ Platypelloid Pelvis.
, Answer: Pelvis that is flat in its dimensions with a very narrow
anterior-posterior diameter and a wide transverse diameter; this
shape makes it extremely difficult for the fetus to pass through the
bony pelvis
◉ *Anatomy:*
Mons Pubis.
Answer: A rounded, fleshy prominence located over the pubic
symphysis
◉ *Anatomy:*
Labia Majora.
Answer: The larger outer folds of the vulva.
◉ *Anatomy:*
Labia Minora.
Answer: The smaller inner folds of the vulva.
