What term is a synonym for "joint" |
articulation |
|
|
What functional joint class contains the least-mobile joints |
synarthroses |
|
|
Of sutures, symphyses, and synchondroses, which are cartilaginous joints |
symphyses and synchondroses |
|
|
How are joint mobility and stability related |
the more stable a joint is the less mobile it is |
|
|
What are 2 layers of the articular capsule |
fibrous layer and synovial membrane |
|
|
How do bursae and tendon sheaths improve joint function |
they make up the wall of the articular capsule |
|
|
Generally speaking, what factor is most important in stabilizing synovial joints |
muscle tendons that cross the joint |
|
|
What is the importance of weeping lubrication |
helps keep the joint cartilages nourished and "lubricates" the joint surfaces |
|
|
John bent over to pick up a dime. What movement was occurring at his hip joint, at his knees, and between his index finger and thumb |
Hip: flexed Knees: extended Thumb: opposition |
|
|
On the basis of movement allowed, which of the following joints are uniaxial
hinge, condylar, saddle, pivot |
hinge and pivot |
|
|
Of the five joints studied in more detail-- hip, shoulder, elbow, knee, and temporomandibilar-- which two have menisci? Which act mainly as a uniaxial hinge? Which depend on mainly on muscles and their tendons for stability? |
Have menesci: knee and temporomandibular Uniaxial hinge: elbow and knee Muscle/Tendon stability: shoulder |
|
|
What does the term "arthritis" mean |
inflammation of the joint |
|
|
How would you determine by looking at someone suffering from arthritis if he/she has OA or RA |
OA: pain, particularly on arinsing, which is relieved with light exercise, and enlarged bone ends -- due to spurs-- in affected joints
RA: pain, swelling, joint deformations that tend to be bilateral and crippling
|
|
|
What is the cause of lyme disease |
spirochete bacteria and transmitted by a tick bite |
|
|
exhibit a joint cavity |
synovial joints |
|
|
types are sutures and syndesmoses |
fibrous joints |
|
|
bones connected by collagen fibers |
fibrous joints |
|
|
types include synchondroses and symphyses |
cartilaginous joints |
|
|
all are diarthrotic |
synovial joints |
|
|
many are amphiarthrotic |
cartilaginous joints |
|
|
bones connected by a disc of hyaline cartilage or fibrocartilage |
cartilaginous joints |
|
|
nearly all are synarthrotic |
fibrous joints |
|
|
shoulder, hip, jaw, and elbow joints |
synovial joints |
|
|
Freely movable joints are |
diarthroses |
|
|
Anatomical characteristics shared by all synovial joints include all except
articular cartilage; a joint cavity; an articular capsule; presence of fibrocartilage |
presence of fibrocartilage |
|
|
Factors that influence the stability of a synovial joint are |
shape of articular surfaces; presence of strong reinforcing ligaments; tone of surrounding muscle |
|
|
The description "Articular surfaces deep and secure; capsule heavily reinforced by ligaments and muscle tendons; extremely stable joint" best describes |
hip joint |
|
|
Ankylosis means |
immobility of a joint due to fusion of its articular surfaces |
|
|
An autoimmune disorder in which joints are affected bilaterally and which involves pannus formation and gradual joint immobilization |
rheumatoid arthritis |
