Exam 2 Arthrology Part 1 Flashcards
Synarthrosis
Immovable
Amphiarthosis
Slightly moveable
Diarthrosis
Freely moveable
Bones fastened together by thin layers of fibrous (dense) connective tissue
Fibrous
Bones joined by a fibrous band which forms an interosseous ligament
Syndesmosis
Movement classification for syndesmosis:
Amphiarthrosis
Only b/t some bones of the skull
Suture
Bones joined by a very short fibrous band which forms a sutural ligament
Suture
Suture movement classification:
Synarthosis
Articulation b/t tooth root & bony socket; consists of a very short fibrous band which forms a ‘periodontal ligament’
Gomphosis
Gomphosis movement classification:
Synarthrosis
Connection consist of hyaline cartilage &/ or fibrocartilage
Cartilaginous
Bones are united by a plate of hyaline cartilage
Synchondrosis
Synchondrosis movement classification:
Synarthosis
Articular surfaces are covered by a thin layer of hyaline cartilage, which in turn is attached to a pad of fibrocartilage
Symphysis
Movement classification of symphysis
Amphiarthrosis
Synchondrosis & symphysis =
Cartilaginous
Syndesmosis, suture & gomphosis =
Structure
Space b/t articulating bones filled w/ synovial fluid
synovial
Synovial movement classification=
Diarthrosis
Articular surfaces are covered w/ a thin layer of _______ cartilage
hyaline
Synovial joint is encased in capsule (articular) composed of:
Fibrous membrane (capsular ligament) Synovial membrane
Thick, fibrous outer layer contiguous with periosteum of bones
Fibrous layer/ membrane
Thin inner membrane covering all non-cartilaginous surfaces
Synovial membrane
Synovial membrane has two layers:
Fibrous layer
Cellular layer
Superficial (next to the fibrous membrane); collagen fibers & fibroblasts
Fibrous layer
Deep (next to the synovial cavity); synoviocytes, blood vessels, and a scattering of collagen fibers
Cellular layer
Cells making up the cellular layer of the synovial membrane
Macrophage- like cells
Fibroblast- like cells
Immediately next to synovial cavity; phagocytic
Macrophage- like cells
Next to the fibrous layer of the synovial membrane; produce hyaluronic acid component of synovial fluid
Fibroblast- like cells
Interior of the joint, filled w/ synovial fluid
Synovial cavity
Viscous, gel like fluid composed of hyaluronic acid & blood plasma
Synovial fluid
Fibrocartilage pad located b/t articular disc
Articular disk/ meniscus
Closed synovial fluid filled sac
Bursa
