– Ischium: bottom
posterior, supports
weight while sitting
– Pubis: bottom anterior
portion
Ilium Portion of Coxa
• Iliac Crest: muscles
attach here
• Anterior Superior Iliac
Spine: muscles attach
here
Ischium portion of coxa
• Ischial Tuberosity:
flattened roughened
area
– muscles attachment
site
• Ischial Spine:

Auditory Ossicles
• 3 tiny bones:
– Malleus: connected to
ear drum “hammer”
– Incus: “anvil”
– Stapes: conducts
vibrations to inner ear
“stirrup”
• From lateral to medial
