Fiberous joints |
Fibrous joints are where adjacent bones are strongly united by fibrous connective tissue.
Held together with dense dyno vial connective tissue. No synovial cavity |
|
|
Cartilaginous Joints |
Joints made up completely of cartilage. (either hyaline or fibrocartilage)
Found between costal cartilage and sternum. Also found in epiphyseal plate |
|
|
Synovial joints |
Allow for movement. Hyaline cartilage covers the surface and synovial fluid lubricates it all within a synovial capsule |
|
|
3 kinds of joints |
Synthrosis: immovable. [Fiberous] Amphiarthrosis: bend a little [Cartilaginius] diarthrosis : freely moves [synovial] |
|
|
Common traits of synovial joints |
- fluid filled capsule surrounding articular (hyaline) cartilage |
|
|
Knee Joint Deep Dive |
Femur, tibula and tibia are layered with articular (hyaline) cartilage Meniscus: act as shock absorbers between the bones. Stabilizes it as well (cup shaped) Synovial fluid: within the synovial joint nourishes cells, removes waste, lubes articular surfaces. Lateral/Fibular and Medial/Tibular Collateral Ligaments: Stop knee from twisting (these are on each side of the knee)
Anterior Cruciate Ligament: Prevents forward displacement Posterior Cruciate Ligament: prevents backwards displacement |
|
|
Synovial Joint Layers |
Joint Cavity (s-fluid filled) Synovial Layer/Capsule Fiberous layer/Capsule |
|
|
What makes an articular capsule |
(1) the outer fibrous membrane that may contain ligaments and (2) the inner synovial membrane that secretes fluid |
|
|
When a knee is hit from the left, what things tend to break together? |
Medial Meniscus, Anterior cruciate ligaments and medial collateral ligaments |
|
|
Define Bursa |
Little coushin full of synovial fluid. Coushins bind structures and helps them move easily. Hamburger bun shaped |
|
|
Tendon Sheet |
Like bursa, synovial filled tube that encapsulates a tendon. Hot dog bun |
|
|
Bursitus |
When a bursa becomes inflammed. Becomes painful |
