principals of articulation

Question 1

How can joints be classified

Answer 1

they can be classified based on structure or function

Question 2

what are the joint classifications based on structure

Answer 2

fibrous, cartilaginous, or synovial.

Question 3

What are the joint classifications based on function

Answer 3

degree of movement permitted:
synarthrosis (immovable)
amphiarthrosis (partially moveable)
diarthrosis (freely moveable)

Question 4

What are some features of fibrous joints and name 3 types

Answer 4

no synovial cavity
held together by a fibrous connective tissue
permits little or no movement (synarthrosis/amphiarthrosis)
3 types: suture, syndesmosis, interosseous membrane

Question 5

Where are suture joints found, what is their function and what are their properties

Answer 5

found in the skull, unites skull bones.
A thin layer of dense, irregular tissue.
interlocking edges provide strength and no movement.

Question 6

Give an example of a syndesmosis joint, what are its properties

Answer 6

example would be the tibiofibular joint, which crosses a greater distance than the suture, permits slight movement.

Question 7

What is the function of an interosseous membrane

Answer 7

sheet of dense connective tissue. It binds adjacent long bones.

Question 8

What are the features of cartilaginous joints and what are the 2 types

Answer 8

no synovial cavity, held together by fibrocartilage or hyaline cartilage.
minimal or no movement,
2 types: synchondrosis and symphysis

Question 9

What is the connective tissue in synchondrosis cartilaginous joints and give an example where it can be found

Answer 9

hyaline cartilage

epiphyseal plate

Question 10

What is the connective tissue in symphysis cartilaginous joints and give an example

Answer 10

fibrocartilage

junction of the manubrium and the sternum or between the intervertebral discs
