Pelvic Gridle Flashcards
How many bones does the Pelvic Girdle Consist of?
2 Bones called Coxal.
What is the point where the Pelvic bones join Anteriorly?
They join together at a join called the Pubic Symphysis
Where do the Coxal bones join together on the Posterior portion of the Body?
They unite posteriorly with the Sacrum.
What are the Sacroiliac Joints?
This is the point at which the 2 coxal bones unite posteriorly with the Sacrum.
What is the Function of the Bony Pelvis/ Pelves?
The Bony pelvis provides a Strong, Stable support for the vertebral column and pelvic and lower abdominal organs. The Pelvic girdle
What is a Bony Pelvis or Pelves?
This is the complete ring of the hip bones, Pubic Symphysis, Sacrum and Coccyx forms a Deep structure called the Bony Pelvis.
What is the name of the Socket for the Head of the Femur to articulate with?
Acetabulum.
What are the 3 Main Parts of the Pelvic bone?
Ilium, Ischium, Pubis.
What are all the Components of the Ilium?
From the Lateral view of the Coxal bone:
Gluteal lines, Iliac crest, Tubercle of the Iliac crest, Ala, Anterior-Superior Iliac spine, Anterior-Inferior iliac Spine, Body of Ilium, Posterior-superior iliac spine, Posterior-inferior iliac spine, Greater Sciatic notch.
Medial view:
Articular Surface, iliac tuberosity, Iliac Fossa, Arcuate Spine.
What are all the components of the Ischium?
Lateral view/ Medial view:
Body, Ischial spine, Lesser sciatic notch, ischial tuberosity, Ramus of the Ischium, Obturator foreman.
What are all the components of the Pubis?
Lateral view:
Superior Ramus of Pubis, Pubic Tubercle, Inferior Ramus of the Pubis.
Medial view:
Pectineal line, Body of pubis, pubic crest, pubic symphysis.
What is the largest foreman in the Skeleton?
Obturator Foreman.
What portion of the Iliac is superior to the Body?
The “Ala” is the wing portion of the Coxal bone.
What portion of the Iliac is superior to the Body?
The “Ala” is the wing portion of the Coxal bone.
What is the Superior border of the Ilium?
The Iliac Crest.
When the Iliac crest ends on the Anterior side what does it form?
The Anterior-Superior Iliac spine.
ASIS
What are the Main differences in male Pelvis bones to Females?
The Males bones generally have more dense bones and more defined surface markings and the females True pelvis is larger and wider to accommodate for child birth.
What are the Surface markings of the Ilium portion of the Pelvis?
Iliac Crest, Tubercle of the iliac crest, Ala (Superior to the body), ASIS and AIIS, Body, Acetabulum, PSIS, PIIS, Greater Sciatic Notch.
Iliac Fossa, Arcuate line.
What are all the surface markings of the Ishium portion of the Pelvis?
Body, Ischial Spine, Lesser Sciatic notch, Ischial Tuberosity, Ramus of the Ischium, Obturator Foreman.
What are all the surface markings of the Pubic portion of the Pelvis?
Superior Ramus of the pubis, Pubic Tubercle, inferior Ramus of the Pubis, Pectineal line, body pubic crest, pubic symphysis.
Why is there a true and false pelvis?
This is because the inferior portion of the Pelvis contains the Pelvic cavity and the Superior portion contains the Abdominal Cavity.
What are the Gluteal lines and where are they located?
The Posterior, Inferior ad Anterior lines are used for Gluteal muscle attachment on the outer lateral surface of the wing.
What is Pelvimetry?
This is the measurement of the Inlet and Outlet of the birth canal.
What are the 2 main parts the Ilium is divided into?
The superior Ala and the Inferior Body.
