Question | Answer |
---|---|
Kinesiology | the multidisciplinary study of physical activity or movement |
joint articulation | the connecting point of two bones |
arthrology | the study of joints |
synarthroses | immovable joints that lack a synovial cavity and are held together by fibrous connective tissue |
sutures | joints where a thin layer of dense fibrous connective tissue unites the bones of the skull |
syndesmoses | slightly movablt joints where bones are connected by ligaments |
gomphosis | an immovable joint in which a conical process fits into a socket held in place by ligaments |
amphiarthroses | slightly movable joints connected by fibrocartilage |
fibrocartilage | specialized connective tissue with thick collagen fibers |
diathroses | freely movable joints |
articular cartilage | connective tissue covering the ends of long bones |
synovial membrane | a double layer of connective tissue that lines joint cavities and produces synovial fluid |
synovial fluid | a lubricating substance found in joint cavities |
synovial joint | freely movable joint |
pivot joint | a freely movable joint in which a bone moves around a central axis, creating rotational movement |
gliding joint | a freely movable joint that allows bones to make a sliding motion |
hinge joint | a freely movable joints that allows flexion and extension |
concave | a half-circle indention to a surface |
convex | a half-circle shaped protrusion on a surface |
condyloid joints | freely movable joints that allow bones to move about one another in many different directions but not to rotate |
ball-and-socket joint | freely movable joints in which a rounded end of one bone fits into an indented end of another bone; allows for widest range of motion |
saddle joint | a freely movable joint between two bones with complementary shapes |
flexion | movementthat decreases the angle between two bones |
extension | movement that increases the angle between two bones |
hyperextension | movement beyond the natural range of motion |
abduction | movement of the limbs away from the midline of the body |
adduction | movement of the limbs toward the midline of the body |
rotation | movement of a bone on an axis, toward or away from the body |
bursitis | an innflammtion of synovial cavity from exsessive stress or tension |
arthritis | an inflammation of an entire joint |
rheumatic fever | a bacterial infection that can be carried in the blood to the joints |
rheumatoid arthritis | a connective tissue disorder resulting in severe inflammtion of small joints |
primary fibrositis | an inflammtion of the fibrous connective tissue in a joint |
osteoarthritis | a degenerative joint disease |
gout | an accumulation of uric acid crystals in the joint at the base of th elarge toe and other joints of the feet |
closed kinematic chain | body part farthest from the trunk is fixed |
open kinematic chain | body part farthest from the trunk is free |
