because when we run, we need bend our knees to get more strength from the knees and to hold our weight when we stand
In anatomy "superior" means above, as in if someone is standing up the hip is above the knee. The hip joint is the first joint higher than the knee, so it is the first joint "superior" to the knee.
The shoulder joint is a ball and socket joint - which allows for the greatest range of motion, while the knee is a pivotal hinge joint, because in the human body, there is no need for a knee that can rotate in any direction, but an arm that can do so is almost imperative.
Yes. Distal means farther from the point of attachment or from the center of the body. So the knee is distal to the hip, and the food would be distal to the knee and so on.
The hip joint is a ball and socket joint so it possible to move the leg around in a 360 degree circle. The knee joint is a pivotal hinge joint so it can only move backwards and forwards with slight rotation.
Cartilage in the elbow joint and knee joint cushion the bones in the joints so the easily glide over each other. As you age, these become thinner and finally disappear. The joint then are very painful.
There is not a ball and socket joint at the knee. It is a complex hinge joint. The knee joint begins to wear out from walking and carrying most of our weight. As we age, the socket may need to be replaced. If we walked up and down the Empire State Building 10,000 times, that is how much walking we will do in a life time.
No, the knee is not a ball and socket joint. It is a hinge joint, allowing primarily flexion and extension movements. Ball and socket joints, like the hip joint, allow for a wider range of motion in multiple directions.
Of course they do! how would they walk if they didnt?? You probably just cant see it when they are kittens because they are so tiny.
a knee The joint in the middle of a leg is called a knee. It enables the person to walk upright. Men have this joint as well, so it is a universal anatomical feature.
A horse's hock is located on the back legs of the horse. It is the joint that would act as a knee for the horse and is the large joint located about half way up the horse's leg. Additional information: in comparative anatomy the hock joint is equivalent to a human ankle so it bends backward instead of forward. The stifle joint in a horse actually the same as a human knee joint.
the elbow is a hinge joint.. the knee is a hinge joint and it rotates. i m just reaching in my own mind.. so i have not looked anything up to answer this.. i do know the knee has incrediable shock absorbers called menicus in both the top and bottom of the joint.. these little disks of shock absorbing fluid take a lot more pressure than an elbow could provide.. that's my observations of those two joints..
The maximum frictional force in the knee joint would be equal to the weight supported by the knee. So for a person supporting 66.0 kg of their mass on the knee, the maximum frictional force would be 66.0 kg multiplied by the acceleration due to gravity (9.81 m/s^2), which equals 647.46 N.
