Synarthroses 2 subcategories |
•Fibrous Joints-bones connected by a solid mass of connective tissue proper •Cartilaginous Joints-bones connected by a solid mass of cartilage |
Limited in movements |
|
|
Diarthrosis or Synovial Joint |
Bones connected by a hollow sleeve of connective tissue proper •the most mobile joints •most common joint in body •many types of synovial jointsfi |
|
|
|
Fibrous Joints |
1. Interosseous membrane 2. Syndesmosis 3. Sutures |
|
|
|
Interosseous Membrane |
Bones joined by sheets dense connective tissue. •a sheet of thick collagen fibers •sheets help hold bones in place |
Inter-=between+oss=bone |
|
|
Syndesmosis |
Bones joined by bands or thin layers of dense connective tissue •Dento-alveolar Syndesmosis or gomphosis:they restrain •cranial syndesmoses: pterygospinous ligament, stylohyoid ligament •vertebral syndesmoses: interspinous ligament, intertransverse ligament •Distal tibiofibular syndesmosis |
|
|
|
Sutures |
Close bony junctions with minimal amounts of connective tissue, growth surface, shock absorption zones. Plane sutures, squamous sutures, serrate sutures, denticulate sutures |
|
|
|
Plane sutures |
Side by side |
|
|
|
Squamous sutures |
Bones overlap a little |
|
|
|
Serrate sutures |
Look like zigzags |
|
|
|
Denticulate sutures |
-Like teeth they come together -Hold the two bones together |
|
|
|
Cartilaginous joints |
Two types: synchondrosis and symphysis |
|
|
|
Synchondrosis |
Together with cartilage
Epiphyseal growth plate: growth plate in developing bones, plates at the ends of bones, hyaline cartilage, temporary joints |
|
|
|
Symphysis |
To make to grow together
Intervertebral discs: dense fibro cartilage
Symphysis pubis |
|
|
|
Synovial Joints |
Provide for the majority of skeletal movement in the body. Knee, shoulder, and elbow. A sleeve of connected tissue |
|
|
|
Articular Cartilage |
Great for reducing friction Low friction Hyaline cartilage Smooth |
|
|
|
Fibrous membrane or capsular ligament |
Appears as a thickened continuation of the periosteum, which it is indistinguishably continuous with, spanning beyond the end of one bone to blend intimately with the periosteum over the adjoining bone. Made of dense irregular connective tissue |
|
|
|
Synovial membrane - internal layer |
A cushion keeps it lubricated, contains synovial fluid, healthy when moving |
|
|
|
Synovial fluid |
It coats and lubricates the articular cartilage, helps provide it with nutrients |
|
|
|
Meniscus |
Is moon shaped Provides a stable surface joint Improves alignment Shock absorber Fibro cartilage |
|
|
|
Articular Discs |
Fibrocartilage structures that divide the synovial cavity into smaller cavities Shock absorption A fit btw articulating boney surfaces |
|
|
|
Labrum |
Ball and socket joints Fibro cartilage lip that extends from the edge of the joint socket |
|
|
|
Hinge joint |

|
|
|
Plane joint |

|
|
|
Saddle joint |
Back (Definition) |
|
|
|
Bicondylar joint |
Back (Definition) |
|
|
|
Ligaments |
They are bone to bone connections It prevents certain levels of movement It's made of dense irregular connective tissue and dense regular connective tissue Poor blood flow |
|
|
|
Bursae |
Is a small sac-like structure interposed btw structures that generate significant amounts of friction Located at areas of friction btw neighboring tissues Function they reduce friction |
|
|
|
Retinaculum |
These are collagenous bands of connective tissue that form tunnels through which multi-joints tendons pass as they course into the hands and feet. |
|
|
|
Structure of synovial sheath |
Is a modified bursa that wraps around a tendon to protect it from friction on all sides |
|
|
|
Function of the synovial sheath |
Allows for frictionless movement |
