Study Notes
Pelvic Girdle Function
- Primary functions:
- Bears weight of the upper body during sitting and standing
- Transfers weight from axial to lower appendicular skeleton for standing and walking
- Provides attachment for locomotion/posture muscles and abdominal wall muscles, withstanding generated forces.
Pelvic Girdle Bones
- Composed of:
- Right and left hip bones (coxal/pelvic bones)
- Each forms from the fusion of three bones: ilium, ischium, pubis
- Sacrum: formed by fusion of five originally separate sacral vertebrae
- Right and left hip bones (coxal/pelvic bones)
Differences Between Male and Female Pelvis
-
General Structure
- Male: Thick and heavy, deep
- Female: Thin and light, shallow
-
Pelvic Inlet/Aperture:
- Male: Narrow and deep, tapering
- Female: Wide and shallow, cylindrical
-
Pelvic Outlet/Aperture:
- Male: Comparatively small, heart-shaped and narrow
- Female: Comparatively large, oval and rounded
-
Pubic Arch/Subpubic Angle:
- Male: Narrow (<70°), inverted V shape
- Female: Wide (>80°), nearly 90°
-
Obturator Foramen:
- Male: Round
- Female: Oval
-
Acetabulum:
- Male: Small
- Female: Large
-
Greater Sciatic Notch:
- Male: Narrow
- Female: Wide
Pelvic Cavity Contents
- Terminal parts of ureters
- Urinary bladder
- Rectum
- Pelvic genital organs
- Blood vessels, lymphatics, and nerves
Pelvic Diaphragm Muscles
- Coccygeus
- Levator Ani
- Pelvic fascia (connective tissue space between peritoneum and pelvic walls)
Pelvic Artery/Anastomosis
- Gonadal (testicular in male, ovarian in female)
- Superior rectal
- Median sacral
- Internal iliac
Pelvic Kinematics (Nutation/Counternutation)
- Nutation: Sacral base tips forward and downward relative to the ilium
- Counternutation: Sacral base tips backward and upward. The reverse of nutation.
Lumbo-Pelvic Rhythm
- Forward bending: Pelvis tilts anteriorly, lumbar spine flexes to maintain balance and greater range of motion
- Returning to upright position: Lumbar spine extends as pelvis tilts posteriorly.
