Movement can occur in two planes

Question 15

A metacarpophalangeal (MP) joint, which has oval articulating surfaces and permits movement in two planes, is what type of synovial joint?

Answer 15

Condylar

Question 16

What is a function of synovial fluid?

Answer 16

• Lubricates the joint
• Provides nutrients for articular cartilage
• Absorbs shock within the joint

Question 17

What is the differences between fibrous joints and cartilaginous joints and synovial joints

Answer 17

Fibrous joints- occur where bones are held together by dense regular (fibrous) connective tissue
Cartilaginous joints- occurs where bones are joined by cartilage
Synovial joints-Has fluid-filled joint cavity that separates the cartilage-covered articulating surfaces of the bones. The articulating surfaces are enclosed within a capsule, & the bones are also joined by various ligaments

Question 18

Describe all joints that are functionally classified as synarthroses

Answer 18

• Tooth to jaw
• Lambdoid suture (connects occipital & parietal bones)
• Epiphyseal plates in growing bones; costochondral joints

Question 19

Describe the basic anatomy of the glenohumeral joint

Answer 19

Ball and socket joint formed by the articulation of the head of the humerus and the glenoid cavity of the scapula.
*Permits greatest range of motion of any joint in the body

A freely mobile joint

Question 23

A gomphosis is

Answer 23

Resembles a peg in socket. The only ones in the human body are the articulations of the roots of individual teeth with the sockets of the mandible and the maxillae

Question 24

Anatomy of synovial joints

Answer 24

Freely mobile atriculations. Bones in this joint are separated by a space called a joint cavity.
These joints have several basic features:
*An articular capsule
*joint cavity
*synovial fluid
*articular cartilage
*ligaments
*nerves and blood vessels

Question 25

All synovial joints are classified as

Diarthroses
