yes the knee joint is stronger
it can move up the xylem and in both directions in the phloem
Ball and socket
Because like the elbow, the knee is a hinge joint. It has a groove in it that keeps the movement in single plane. This makes the musculature required to articulate the joint simpler. To move in more than one plane a joint needs either many bones in it (like the wrist), or has to be a ball and socket construction with muscles all round it to pull it in many directions (like the hip or shoulder).
The 3 body parts that allow you to move in many directions are the hip joint, the shoulder joint, and the wrist joint. These joints have a wide range of motion and allow for movements in multiple directions.
well actually your knee cap does move see the kneecap is connected by muscles which allow it to move with the joint. it is connected to the femur . try this extend your leg outward you 'll notice your knee feels looser now flex your leg inward you'll notice your knee feels tighter. the point is your knee cap does move you just cant notice it
not of there wooden
Cheeta makes mounts that move in all directions.
If you think about it, the knee is a working mechanism that acts as a joint and helps you move easier. It can be easy to strain it or fall on it or overuse it causing injuries. There are many working parts in there.
Huh? You are an animal with bilateral symmetry. Check how many directions you are able to move.
Different directions, they just move slower until they stop and then you have ice.
All directions.
