3

SI joints are mobile ___ joints that support the trunk, guide movement and help absorb compressive forces

diarthrodial (synovial)

4

interlocking elevations and depressions on the SI jt produces the ___ effect of the sacrum, distributing axial compressive forces

keystone

5

bc of SI jt, forces from LE divide, heading upward twd the ___, ant twd the ____, and downward forces of gravity on the ___ split to both sides

spine
pubic symph
spine

6

SI jt develops over time, and in later years, many males will have interarticular ___ across them & therefore lost motion

adhesions

7

during locomotion, the SI joints flex/extend in ___ with the corresponding hip joint, which are ___ at the other joint by opposite movement

unison
mirrored

8

-as one innonimate flexes (PI) the ipsilateral sacral base moves AI, this is called ___
