Articulation
Joint
How are articulations usually named?
Typically named after the specific bones they connect
4 types of joints
Bony, fibrous, cartilaginous, synovial
What are the 3 types of fibrous joints
Suture, gomphoses, syndesmoses
Suture
Fibrous joint found exclusively in the skull
Gomphoses
Fibrous joint that connects teeth to their sockets; held by a periodontal ligament
Syndesmoses
Fibrous joint that bounds bones by long collagenous fibers
2 types of cartilaginous joints
Synchondroses, symphyses
Synchondroses
Bones joined by hyaline cartilage
Ex: epiphyseal plate
Symphyses
Bones joined by fibrocartilage
Ex: pubis symphysis
Synarthrotic joint movement
Allows for limited to no movement
Amphiarthrotic joint movement
Allows for moderate movement
Diarthrotic joint movement
Allows for free movement
Types of synarthrotic joints
Suture, gomphoses, syndesmoses
Types of amphiarthrotic joints
Synchondroses, symphyses
Types of diarthrotic joints
Ball and socket, condylar, saddle, plane, hinge, pivot
How are synovial joints stabilized
Ligaments, tendons, joint capsule, shape, muscle action
Synovial joint
Lever
Elongated, rigid object that rotates around a fixed point
Components of a lever
Fulcrum (F), effort (E), resistance (R)
Definition of fulcrum, effort, and resistance in a lever
Fulcrum: fixed point of rotation
ex: elbow joint when moving forearm
Effort: muscle creates movement
Resistance: weight being moved
Level classes
First class: EFR, head movement at neck joint
Second class: FRE, standing on tiptoes
Third class: REF, biceps lifting forearm
