APK 2100C Chapter 9 Exam Study Guide.
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
Cartilaginous joints - answer✔The articulating bones are united by cartilage.
Cartilaginous joints lack a ___________ and are not highly movable. - answer✔joint cavity
What are the types of cartilaginous joints? - answer✔Synchondroses and symphyses.
Synchondrosis - answer✔A joint where hyaline cartilage unites the bones.
Symphysis - answer✔A joint where fibrocartilage unites the bones. They are slightly moveable
joints that provide strength with flexibility.
Synovial - answer✔The most movable joints of the body, and all are diarthroses. Each contains
a fluid-filled joint cavity.
The ends of opposing bones in synovial joints are covered by __________ cartilage composed
of hyaline cartilage. - answer✔articular
Joint Articular Cavity - answer✔A feature unique to synovial joints, the joint cavity is a potential
space that holds a small amount of synovial fluid.
The synovial joint cavity is enclosed by a two-layered ____________.Articular Capsule -
answer✔articular capsule
What is the function of the synovial membrane? - answer✔To make synovial fluid.
Synovial fluid - answer✔The viscous liquid inside the joint cavity. It resembles raw egg white.
Weeping Lubrication - answer✔Occurs when the pressure placed on joints during normal
movement squeezes synovial fluid into and out of the articular cartilages. This nourishes the
cells in the articular cartilages, allowing the adjoining bones to move across each other with a
minimum of friction.
Reinforcing ligaments - answer✔Some synovial joints are reinforced and strengthened by
bandlike ligaments. Most are capsular.
Synovial joints are richly supplied with sensory _____________ that innervate the articular
capsule. - answer✔nerve fibers
