3 structural classification of joints ?
- Fibrous joints(bones held together by fibrous C.T
- Cartilaginous joints (…by cartilage)
- Synovial joints (…by ligaments)
The point of contact between 2 bones, bone and teeth or bone and cartilage?
Joints
3 Functional classification of joints ?
SYNARTHROSIS (an immovable joint)
AMPHIARTHROSIS (a slightly movable joint)
DIARTHROSIS (a freely movable joint)
What do joints lack ?

Dense connective tissue
3 types of fibrous joints
- SUTURES
- SYNDESMOSES
- GOMPHOSES
What Occurs only between bones of the skull?
Sutures
Synostosis: suture joint that has ossified?
Sutures
What permits slight movement with more/longer fibrous C.T. ?
Clue: between the tibia and fibula in the leg.
SYNDESMOSES
Immovable Joint?
Gomphoses
What joint in which a cone-shaped peg fits into a socket?
GOMPHOSES
What joints of the teeth with the sockets of the maxillae and mandible?
GOMPHOSES
Lacks a synovial cavity ? Clue: allows little or no movement.
Cartilaginous Joints
What Joint is tightly connected by cartilage ?

Connects the bones
Symphyses
What allows a joint to b freely movable?
