Study of joints or articulation of bones
ARTHROLOGY
Functional classification of bones joints that means immovable
SYNARTHROSES
Functional classification of bones joints that means slightly movable
AMPHIATHROSES

DIATHROSES
Type of joint that do not have joint cavity and is united by fibrous and connective tissue’s
FIBROUS JOINTS
An immovable joint or very slightly movable joint united by sheets of fibrous tissue. Example inferior tibio fibular joint
SYNDESMOSIS
An immovable joint occurring only in the skull
SUTURES
An immovable joint that occurs only in the roots of the teeth
GOMPHOSIS
Three types of structural classification of joints
- FIBROUS
- CARTILAGINOUS
- SYNOVIAL
Slightly movable joints That are designed for strength and shock absorbency
SYMPHYSIS
Animal double join and immovable joint that contains a rigid cartilage that unites two bones. Example epiphyseal plate
