What type of joint has little movement? ampiarthroses
What type of joint has free movement? diarthroses
What type of joint has angular motion in one plane? hinge joint
What type of joint moves only in rotation? pivot joint
oval articular face nestles within a depression in the opposing surface ellipsoidal joint
nesting concave, convex saddle surfaces saddle joint
round head fits within cup-shaped depression - all types of angular and rotational movement ball and socket joint
flattened or slightly curved faces that slide across one another - movement is slight gliding joint
In joint structure, what is the external layer called? capsular ligament
In joint structure, what is the internal layer called? synovial membrane
What coats and lubricates the articular cartilage to reduce friction within the joint? synovial fluid
In what joint is meniscus found? knee joint
What does meniscus provide to the joint? shock absorption
In what types of joints is labrum located? ball and socket
What helps to deepen the socket and increase area of contact? labrum
What binds bone to bone? ligaments
What is located throughout the body where there are areas of friction between neighboring tissues? bursae
holds tendons firmly to the bones when muscles contract across multiple joints - prevents the tendon from being displaced upward away from the joint surface retinaculum
modified bursa that wraps around a tendon to protect it from friction on all sides - found in tight confines of wrist, ankle and digits synovial sheath
fixed end origin
mobile end insertion
What envelops each muscle fiber? endomyosin
What envelops around a group of muscle cells - fasciculus? perimysium
What forms the outer wrapping around the bundles of fasciculi to form the belly of an individual muscle? epimysium
shortening of the muscle concentric contraction
lengthening of the muscle eccentric contraction
static contraction of the muscle isometric contraction
