Arthrology
Joint
Syndesmology
Ligament
Joint
Usually has movement
Articulation between 2 bones
How is movement produced in a bone.
The shape of the bony surface determines movement
2 joint classification
- Structure
2. Function
What is structure based on?
The material holding it together
3 types of structure types for a joint
(What is it made of)
- Fibrous
- Cartilaginous
- Synovial
(Fcs)
Fibrous joints (structure)
Held together:
Fibrous connective tissue
Cartilaginous (structure)
Held together :
Cartilage
( hyaline / fibrocartilage)
Synovial (structure)
Most joint are this
Many structure involved to hold joint together
3 levels of joint Functions
(SAD)
- Synarthrosis ( little / no movement)
- Amphiarthrosis ( some movement)
- Diarthrosis ( freely move able)
Synarthrosis (function)
Little to no movement in a joint
Amphiarthrosis (function)
Some movement in a joint
Diarthrosis (function)
Freely move able joint
Osteokinematics
Movement of a bone
Arthrokinematics
Movements of a joint
3 Types of fibrous joints
SSG
- Suture
- Synedesmosis
- Gomphosis
Suture
Structure: (fibrous joint)
Location:
Function of joint:
Example:
Structure: fibrous
Location: between bones of skull
Function: Synarthrodial (no movement
Example: between 2 bones of cranium
Synedesmosis
Structure (fibrous joint)
Location :
Function of joint :
Example
Structure: fibrous joint Location: between 2 bones Function on joint: Amphiarthrosis ( some movement) Example: Ulna &.radus Fiblia and tibia
Syn-
United together
Gomphosis
Structure (fibrous joint)
Location:
Function:
Example:
Structure: fibrous joint
Location: between tooth and socket
Function; Synarthrodial ( little to no movement)
Example: joint between tooth and socket
Alveolar process
Tooth socket
Thicken Ridge of bone that holds tooth socket
2 Cartliaginous joints
SS
- Synchondrosis ( hayaline cartilage)
- Symphysis (fibrocartilag)
Synchondrosis joint (cartilaginous structure joint)
Structure: cargilaginous
( a part of Synchondrosis (cartilaginous joint)
- Hyaline cartilage
- Often temporary joint
- Usually Ossify ( not always)
- Will fuse
- Loose motion
Located Within metaphysical example (epiphyseal growth plates)
What is a Primary cargilaginous joint
( a part of Synchondrosis (cartilaginous joint)
- Hyaline cartilage
- Often temporary joint
- Usually Ossify ( not always)
- Will fuse
- Loose motion
Located Within metaphysical example (epiphyseal growth plates)
What is the secondary cartilaginous joint
Symphysis Bones joined by fibrocartilag Strong Amphiarthrodial ( some movement) Mobile throughout life
Example I’ve between vertebrae
Symphysis joint
Structure
Function
Example
2ndry cartilaginous joint
Structure: cartliaginous
Function : Amphiarthrodial
( some movement)
Example: vertebrae disk
