Joints

Question 1

2 ways to classify joints

Answer 1

Structure and function

Question 2

Synovial joints

Answer 2

Bones separated by a joint cavity, lubricated by synovial fluid, enclosed in fibrous joint capsule

Question 3

3 examples of synovial joints

Answer 3

Shoulder, elbow, carpal joints, hip, knee, tarsal joints, interphalangeal joints

Question 4

Fibrous joints

Answer 4

Bones held together by collagenous fibers extending from the matrix of one bone into the matrix of the next; no joint cavities

Question 5

3 examples of fibrous joints

Answer 5

Skull sutures, teeth in sockets, and tibiofibular joints

Question 6

Cartilaginous joints

Answer 6

Bones held together by cartilage; no joint cavity

Question 7

3 examples of cartilaginous joints

Answer 7

epiphyseal plates of long bones, intervertebral dicdm and pubic symphysis

Question 8

Three functional classifications

Answer 8

Diarthroses, amphiarthroses, and synarthroses

Question 9

Diarthroses

Answer 9

FREELY moveable synovial joints; same thing as the structural synovial joints

Question 10

3 examples of diarthroses joints

Answer 10

shoulder, elbow, carpal joints, hip, knee, tarsal joints

Question 11

Amphiarthroses

Answer 11

SLIGHTLY movable joints

Question 12

3 examples of amphiarthroses

Answer 12

intervertebral discs, pubic symphysis, tibiofibular joints

Question 13

Synarthroses

Answer 13

Joints with little or NO movement

Question 14

3 examples of synarthroses

Answer 14

Skull sutures, teeth in sockets, epiphyseal plates of long bones

Question 15

Arthroses

Answer 15

Joints

Question 16

Double jointed

Answer 16

Hypermobility; more flexibility in joints
