Ch.9 Flashcards
List functional classifications of joints:
1) presence or absence of space between the articulating bones, called a synovial cavity.
2) the type of connective tissue that binds the bones together.
List three structural categories of joints:
Fibrous
Cartilaginous
Synovial
Which of the joints do NOT have a synovial cavity?

- Maintain the stability of a joint
- Direct flow of the synovial fluid to areas of greatest friction.
- are made of hyaline cartilage
- are only found in the vertebral column

Gliding
Which of the following represents a type of movement where there is a decrease in the angle
between articulating bones?

Which of the following is NOT a factor that influences the type of movement and range of motion possible at a synovial joint?
Structure of the articulating bones Strength and tension of the joint ligaments Use of the joint Arrangement and tension of the muscles Hormones
Use of the joint
Disuse of a limb, like would occur when the limb is in cast, leads to muscular atrophy of the affected joint.
