joints
Fontanelle
the areas where the skull bones have not fully fused together, leaving a space covered by a tough membrane.

structural classifications of joints
fibrous纖維狀
cartilaginous軟骨
synovial滑膜
Functional classification of joints
synarthrosis(very little movement)不動關節
amphiarthrosis (slight movement)微動關節
diarthrosis (freely movable)滑液關節

fibrous
纖維狀
cartilaginous
軟骨
synovial
滑膜
bones joined by collagen fibres, no joint cavity, little to no movement (Ex: syndesmosis, suture, and gomphosis)
fibrous
Bones joined by cartilage, no joint cavity, little to no movement (Ex: synchondrosis-plate of hyaline cartilage unites bones, symphysis-fibrocartilage unites bones)
cartilaginous
Bones jointed are separated by a fluid filled cavity

法氏囊
small fluid-filled sacs found throughout the body, typically located between bones, tendons, muscles, and skin.

Three types of range of motion for synovial joint movements
Nonaxial: Gliding movements only
Uniaxial: Movement in one plane
Biaxial: Movement in two planes
Multiaxial: Movement in or around all three planes
General types of movements for synovial joint movements
- Gliding: one flat bone surface glides or slips over another similar surface
- Angular/rotational movements: increase or decrease angle between two bones
- Other movements: ex. dorsiflexion/plantar flexion, pronation/supination, inversion/eversion, retraction/protraction
six types of synovial joints
- Plane/Gliding
- Hinge
- Pivot
- Condylar
- Saddle
- Ball-and-socket
Gliding/plane joint
slight movement along relatively flat surfaces
six types of synovial joints
- Plane/Gliding: slight movement along relatively flat surfaces (sliding motion)
- Hinge: cylinder nests in trough (flexion and extension)
- Pivot: axle fits into a sleeve (rotation)
- Condylar (ellipsoid): oval surfaces
- Saddle: pair of concave and convex area
- Ball-and-socket
