Lesson 10 Flashcards
2w components of pelvic cavity
Pelvis major (false pelvis or greater pelvis)
Pelvis minor (true pelvis or lesser pelvis)
What is the pelvic cavity
Basin shaped cavity inferior portion of the abdo/pelvic cavity
Where is the pelvic major
Between the illiac fossa superiorly and the pelvic brim inferiorly
What is considered part of the abdominal cavity
Pelvis major
What abdominal viscera does the pelvis major include
Parts of the small intestine and sigmoid colon
Where is the pelvis minionr
Between the pelvic brim superiorly and pelvic diaphragm inferiorly
What is the pelvis minor enclosed by
Sacrum, ischium, pubis and pelvic portions of the ilium
What organs does the pelvic cavity contain
Bladder. Rectum. Internal reproductive organs and some intestinal tract if it reaches
What separates the true and false pelvis
Linea terminalis
Where does the linea terminalis run from and to
Runs from sacral promontory to the symphysis pubis
3 osseous components
Os coxae
Sacrum
Coccyx
3 pats of ox coxae (hip bones)
Ilium (superior)
Ishium (posterior)
Pubis (anterior)
Where do all the os coxae components meet
Acetabulum - where femur meets
Os coxae also known as (2)
Innominate or hip bones
Describe os coxae at birth
Individual bones at birth, fused in adults and meet at acetabulum to fuse
What is the largest hip bone
Ilium
Name of large wing like surface of ilium
Ala
What is the iliac crest
It is the superior margin of the ilum
What is the illiac crest limted by anteriorly and posteriorly
Anteriorly by ASIS and posteriorly by PSIS
Inner part of the ala is
The iliac fossa
Iliac fossa is the origin for what muscle
Iliacus muscle
What does the ilium articulate with postmedially
The saccrum at the SI joints
Greater sciatic notch is sup and inf of what
Sup of ischial spine and inferior of posterior Inferior ishial spine
Pubic bones meet at midline at
Symphsis pubis
Small projections lateral to body of the public bones are
Pubic tubercle
Superior pubic ramus extends….
Laterally from pubic tubercle to ilium
Sharp superior margin of pubic ramus forms the
Pectineal line
Pectineal line is continusous with the ____ and make the
Arcuate line making the pelvic brim
Inferior pubic ramus extends ______ from the body to connect with _____
Inferiorly
Ischium
The inferior pubic ramus + ischium =
Pubic arch
Pubic arch in males vs females angles
Less than 70 in males
More than 80 in females
Inferior portion of os coxae
Ischium bone
Rumus of ischium meets ischium of pubis bone to make
Ischiopubis ramus
What is the ischial tuberosity
Bulky, rough surface of Posteroinferior border of ischium
Ischial spine is superior border of _______ and inferior border of _________
Lesser sciatic notch
Greater sciatic notch
