Anat-Articulations
Stack #214559
| Question | Answer |
|---|---|
| joint/articulation | place where two bones come together/contact each other |
| classification of joints | structural: based on major connective tissue type that binds the bones |
| fibrous joint | connective tissue linking bones has a lot of parallel collagen fibers, allow very little or no movement |
| fibrous joint location | sutures of the skull |
| cartilaginous joint | cartilage connective tissue links bones, can withstand lots of pressure |
| cartilaginous joint location | found in areas where bones are pushed together in daily life, pubic symphysis, interverebral discs |
| synovial joint | allow the greatest degree of movement, structurally complex, increased risk of injury |
| synovial joint location | found throughout the appendicular skeleton-- elbow joint, hip joint |
| articular cartilage | hyaline cartilage covering the ends of bones, like a thin shock absorber |
| joint cavity | only seen in synovial joints, space that contains a small amount of synovial fluid and permits separation of the articulating bones |
| articular capsule | double-layered capsule forming the outer portion of the joint |
| fibrous capsule location | the outer layer of the articular capsule |
| fibrous capsule structure | fibrous layer of dense regular connective tissue |
| synovial membrane location | the inner layer of the articular capsule |
| synovial membrane structure/function | thin layer of aerolar connective tissue whose cells produce synovial fluid |
| synovial fluid | viscous, oily fluid that lubricates and lines articular cartilage surfaces |
| bursa | outpocketing of joint cavity filled with synovial fluid that can extend away from the joint, cushion-like |
| location of bursa | found around most synovial joints and where bones, ligaments, skin, muscles, or tendons overlie each other and rub together |
