Copy of Musculoskeletal Sys: Articulations (bone-to-bone) (5/28/2026)
Read and examine the types, models, and structure of the synovial joints in model 2 (above). Then use the following clues attempt to find examples of each synovial joint.
Clue 1- Condyloid joints can move quite far in one plane, but only a small way in the opposite plain. Flex and extend your wrist (hold out your arm in from of you and point your fingers to the ceiling and then to the floor). Then point your arm strait out and move your hand right to left at the wrist. Does your wrist move as far side-to-side as it did up and down? Does this suggest that the wrist joint is condyloid or ball and socket? Where does 'wrist' fit?
Clue 2 - Move your shoulder around. What type of joint does this seem to match? Where does 'shoulder' fit?
Clue 3 - Examine the picture of the joint between the 1st metacarpal of the thumb (supports the thumb, and is located at the base of the thumb, connecting it to the wrist) and the trapezium (one of many bones of the wrist). Does the trapezium resemble something that might be put on a horse? Where does 'thumb' fit?
Clue 4 - Flex your arm at the elbow (bring your wrist toward your shoulder). How many axes is your elbow able to move through? Where would 'elbow' fit?
Clue 5 - Look to your left; now look to your right. Look to the left again. What kind of joint is your head sitting on? Where does 'vertebrae' fit?
Clue 6 - The bones of your ankle are small and flat. Move your ankle through its entire range of motion. Based on the nature of the bones, the mobility of the ankle, and the fact there is only one example not yet complete, where would 'ankle' fit?
