35
Uniaxial joint types
1. Plana 2. Trochoidea 3. Ginglymus 4. Cochlearis 5. Delabens 6. Spring/Snap joint
36
Biaxial joint types
1. Sellaris 2. Condylaris 3. Spiralis
37
Multiaxial joint types
1. Ellipsoidea 2. Cotylica 3. Spheroidea
38
What are the components of a synovial joint?
1. Gap between at least 2 bones 2. Joint capsule 3. Synovial fluid 4. Hyaline cartilage on opposing surfaces
39
What are the layers of a synovial joint?
1. *Stratum fibrosum* 2. *Stratum synoviale*
40
*Stratum fibrosum*
* Fibrous avascular tissue layer * Transverse fibres, sometimes thickening into ligaments * Ligaments: Capsular, intracapsular or extracapsular * Collateral ligaments - Outside joints *(Support)*
41
*Stratum synoviale*
* Capillary supply * Internal wall of *capsula articularis* * Internal wall covered by *villi synoviales* (Produce synovium) * Synovium fills the *cavitas articularis*
42
Give the types of synovial joint
* Simplex * Duplex * Composita
43
Duplex joints
Two bony surfaces are incompatible Fibrocartilage is needed to assist articulation
44
Duplex joint examples
1. *Discus intervertebralis* 2. *Discus temporomandibularis* 3. *Menisci* in *art. femorotibialis* 4. Acetabular labrum
45
What is the purpose of recesses and pouches in joint capsules?
* Allows flexion * Synovial reservoirs * Soft support for tendons travelling over joint
46
Examples of a hard support for a tendon
* Sesamoid bone * Cartilages
47
Examples of a soft support for a tendon
* Recesses * Bursae synoviales * Vaginae synoviales
