1


joint


any point where 2 bones meet

2


joint names


after bones or articular surfaces involved

3


joint functions


movement
flex bones
 skeletal mobility
hold the skeleton together

4


classes of joints


bony joints

fibrous jjoints

cartilages joints

synovial joints

5


bony (synostoses)  joints


original joint becomes ossified and bones become in effect one bone

6


fibrous (synarthroses) joints

joints held together by collagenous fibers

sutures

gomphoses

syndesmoses

7


sutures


serrate: interwoven very strong

lap: over lay each other

plane: butt up against each other

bones of the skull

8


gomphoses

 


hold teeth in socket

 

9


syndesmoses


long bones joined along shaft by intercrosseous membrane

(tibia/fibula)

10


solid joints


skull bones

11


serrate suture


major bones of skull

12


lap suture


minor bones of skull

sphenoid to temporal

13


plane suture


internal kull bones

bones of the maxilla

14


cartilaginous joints


synchondroses

symphyses

15


synchondroses joint


bones bound by cartilage

epiphyseal plate

16


symphyses joint


bones joined by fibrous cartilage

pubic symphysis

17


anatomy of synovial joint


joined by joint cavity

contains synovial fluid

ends of bone coverd in articular cartilage (hyaline)

enclosed in joint capsule

some contain an articular disc or discs (knee)

 

18


accessory structures of synovial joints


tendons (muscle to bone)

ligaments (bone to bone)

bursae

19
