|---|---|
| What type of joint has no movement? | synarthroses |
| 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 |
