Connective tissue
Sutures and syndesomoses are _ joints
Fibrous
Fibrous joints have _ motion
Very limited
In fibrous joints, motion range depends on _
length of fibers
Syndesmoses are between _ and _ bones
arm and leg
_ is a fibrous joint between tooth and sockets of alveolar processes
Gomphosis
_ ossification is found in the development of the cranial base and long bones
Endochondral
What suture typically fuses in early childhood, but may persist through adult life?

restricted
Synchondroses (growth plates) are a type of _ joint
cartilaginous
Symphyses (fibrocartilage) are a type of _ joint
cartilaginous
_ joints are where bones are enveloped by a joint capsule
Synovial
What joint is highly mobile but also weaker?
Synovial
The articular capsules of synovial joints are composed of:
A fibrous capsule
Synovial membrane (inner)
The movement at joints occurs due to _ moving one bone relative to another
muscles
Muscles only _
contract
Muscles must do what to have an action at a joint?
Cross that joint
Type of fibrous connective tissue connecting muscle belly to bone
Tendon
Type of fibrous connective tissue connecting bone to bone
Ligament (involved in stabilization)
The area where the muscle moves the least during action
Origin
The area where muscle moves the most during action
Insertion
