What is a synarthrosis?
Fixed fibrous joints with little or no movement
Joint with the structure:
Bone - Connective Tissue - Bone
- Art. Fibrosae / Syndesmosis*
- E.g art. dentoalveolaris*
Joint with the structure:
Bone - Cartilage - Bone
- Art. Cartilagineae / Synchondrosis*
- E.g symphysis pelvina*
Joint with the structure:
Bone - Bone - Bone
Give an example.
- Synostosis*
- E.g Radius-ulna joint in an older animal*
Joint with the structure:
Bone - Muscle - Bone
- Synsarcosis*
- E.g. Scapula-Spine*
Joint classification which it continuous but slightly movable.
- Amphiarthrosis*
- E.g Art. sacroiliaca*
Diarthrosis
Art. Synoviales
Joint Classification containing synovial fluid.

Uniaxial joint types
- Plana
- Trochoidea
- Ginglymus
- Cochlearis
- Delabens
- Spring/Snap joint
Biaxial joint types
- Sellaris
- Condylaris
- Spiralis
Multiaxial joint types
- Ellipsoidea

What are the components of a synovial joint?
- Gap between at least 2 bones
- Joint capsule
- Synovial fluid
- Hyaline cartilage on opposing surfaces
What are the layers of a synovial joint?
- Stratum fibrosum
- Stratum synoviale
Stratum fibrosum
- Fibrous avascular tissue layer
- Transverse fibres, sometimes thickening into ligaments
- Ligaments: Capsular, intracapsular or extracapsular
- Collateral ligaments - Outside joints (Support)
Stratum synoviale
- Capillary supply
- Internal wall of capsula articularis
- Internal wall covered by villi synoviales (Produce synovium)
- Synovium fills the cavitas articularis
Give the types of synovial joint
- Simplex
- Duplex
- Composita
Duplex joints
Two bony surfaces are incompatible
Fibrocartilage is needed to assist articulation
Duplex joint examples
- Discus intervertebralis
- Discus temporomandibularis
- Menisci in art. femorotibialis
- Acetabular labrum
What is the purpose of recesses and pouches in joint capsules?
- Allows flexion
- Synovial reservoirs
- Soft support for tendons travelling over joint
Examples of a hard support for a tendon
- Sesamoid bone
- Cartilages
Examples of a soft support for a tendon
- Recesses
- Bursae synoviales
- Vaginae synoviales
