Articulations and Movement (Exam 2)

Question 0

Fibrous joints

Answer 0

2 bones are united by fibrous CT
Exhibit very little to no movement at all

Three classifications:
Sutures
Syndesmoses
Gamphoses

Question 1

Classes of joints

Answer 1

Fibrous
Cartilaginous
Synovial

Question 2

Sutures

Answer 2

Seams between skull bones
Very stable
Opposing bones have interlocking processes

Ex: coronal suture between frontal and parietal bone

Question 3

Syndesmoses

Answer 3

Joins bones to a ligament
Flexible, so some movement can occur

Ex: tibiofibular joint

Question 4

Gamphoses

Answer 4

Specialized joints consisting of pegs and sockets
Held together by CT tissue called periodontal ligaments

Ex: between teeth and mandible and maxilla

Question 5

Cartilaginous joints

Answer 5

Two bones united together by hyaline cartilage or fibro cartilage

Two classifications:
synchondroses
Symphyses

Question 6

Synchondroses

Answer 6

2 bone suited by hyaline cartilage
Little to no movement

Ex: epiphyseal plate
Between the costal cartilage of the 1st rib and the manubrium

Question 7

Symphyses

Answer 7

2 bones joined by fibrocartilage
Flexible, some movement can occur

Ex: pubic symphyses
Intervertebral disc

Question 8

Synovial joints

Answer 8

Articulating bones that are separated by a fluid filled joint cavity

Fluid is called synovial fluid
Includes most joints of the body (ALL joints of articulating limbs)
Highly moveable
