APK 2100C Chapter 9
Test With Solution
Joints/Articulations - ANSWER The rigid elements of the skeleton meet at
these sites.
Where are the weakest points of any skeleton? - ANSWER The joints
How can joints be classified? - ANSWER Either by function or structure.
What does the functional classification focus on? - ANSWER The amount of
movement allowed.
Synarthroses - ANSWER Immoveable joints.
Amphiarthroses - ANSWER Slightly moveable joints.
Diarthroses - ANSWER Freely moveable joints.
What is the structural classification based on? - ANSWER The material that
binds bones together and on the presence or absence of a joint cavity.
What are the structural classifications of joints? - ANSWER Fibrous,
cartilaginous, or synovial joints.
Most fibrous joints are ________________ or only slightly ____________. - ANSWER
immovable; movable
, What are the types of fibrous joints? - ANSWER Sutures, syndesmoses, and
gomphoses.
Sutures - ANSWER Literally, "seams," the bones are tightly bound by a
minimal amount of fibrous tissue.
Where do sutures occur? - ANSWER Only between bones of the skull, and
their fibrous tissue is continuous with the periosteum around these flat
bones.
Systones - ANSWER When the fibrous tissue ossifies, and the skull bones fuse
together. These are closed sutures.
Sysdesmoses - ANSWER The bones are connected exclusively by ligaments,
bands of fibrous tissue longer than those that occur in sutures.
How much movement can occur at a syndesmosis? - ANSWER It depends on
the length of the connecting fibers.
Gomphosis - ANSWER A peg-in-socket joint.
I.e. A tooth with its socket
