inverse
where two bones meet
joint, articulation
Three functional classifications of joints
synarthrosis, amphiarthrosis, diarthrosis
no movement at articulation
synarthrosis
slight movement but ONLY sometimes at articulation
amphiarthrosis
free movement at articulation
diarthrosis
types of synarthrosis
synostosis, synchondrosis, suture, gomophosis
types of amphiarthrosis
symphysis and syndesmosis
types of diarthrosis
synovial
near frontal bone, centered below hairline
synostosis
between first rib and sternum, "small c"
synchondrosis
between skull bones
suture
, -where the tooth meets mandible and maxilla
- adult tooth breaks through baby tooth socket
gomphosis
-between 2 pubic bones
- moves ONLY during birth
symphysis
- between distal end of tibia and fibula (closest to ankle)
- when shifting weight so do not crack fibula
syndesmosis
- synovial capsule
- secrets synovial fluid
synovial
synovial joint functions
lubrication, nutrient distribution, shock absorption, protects articular cartilage
what does synovial fluid do?
lubrication and nutrient distribution
what does fat do?
shock absorption
synovial joint structures
meniscus, ligaments, bursa, fat pads
- channels synovial fluid to articular cartilage at the end of bones
