Fibrous Joints Flashcards
What is a Fibrous Joint in general?
These are joints that have no Synovial Cavity and the Articulating bones are held very closely together by Dense irregular connective tissue.
How much movement do Fibrous joints permit?
They permit Little or No movement.
What are all the Types of Fibrous Joints?
Sutures, Syndesmoses, Interosseous membranes.
What are Sutures?
These are Joints composed of a Thin layer of Dense Irregular connective tissue.
Where are Sutures present in the Body?
They are only found in between the bones of the Skull.
Why are Sutures important in the skull?
They are used for holding bones together and for Shock Absorption.
When are the Suture joints moveable?
They are only movable in the body during Infancy and Childhood.
In older people they are immovable.
What is an example of a Gomphosis / Dentoaveolar joint?
There is only one example of this in the human body, it is found where the Roots of the Teeth fit into their Sockets.
What is Synostosis?
This is when 2 bones fuse together/ Bony Joint.
What is the name for the Degeneration of the Gums Periodental ligament and the bone?
This is called Periodontal Disease.
What are Interosseous Membranes?
These are Fibrous joints that are made of Substantial sheets of Dense irregular connective tissue.
They bind neighbouring long bones together and Permit slight movements.
Where are the 2 principle interosseous membranes located?
They are between the Radius and the Ulna, The Fibula and the Tibia.
What do the Interosseous membranes provide for the body?
They help bind long bones together and permit slight movements.
They act as muscle attachments and help define ROM between neighbouring bones.
