What else can I help you with?
We can move our arms in circular motion but not our knees .why?
Moving our arms in a circular motion is possible due to the structure and range of motion of our shoulder joints. The knee joint, however, is a hinge joint designed primarily for flexion and extension, limiting its ability to move in a circular motion. The ligaments and tendons surrounding the knee joint also restrict its range of motion compared to the shoulder joint.
What plane of motion does the tmj go through?
The temporomandibular joint (TMJ) primarily moves in two planes of motion: hinge motion for opening and closing the jaw, and sliding motion allowing for side-to-side movements and protrusion/retraction. It is a unique joint that can move in multiple directions to facilitate activities like chewing and speaking.
What kind of inclined plane are there?
There are many kinds of inclined planes. Some examples are: driveways, slide, and a ramp. There are many kinds of inclined planes. Some examples are: driveways, slide, and a ramp.
What is to move in a backward motion or direction?
To move in a backward motion or direction is to move in the opposite direction as usual, such as walking, running, or driving in reverse.
Does friction waste more work on longer or shorter planes?
Friction will waste more work on longer planes because the force of friction acts against the direction of motion for a longer period of time. This results in more work being done to overcome friction and move the object along the longer plane.
How many planes of motion does the elbow move in?
The elbow moves in two planes of motion: sagittal (flexion and extension) and frontal (adduction and abduction).
What is the range of motion in the shoulder abduction plane of motion?
The range of motion in the shoulder abduction plane of motion is typically around 180 degrees, allowing the arm to move away from the body sideways.
What is the range of motion in the shoulder flexion plane of motion?
The range of motion in the shoulder flexion plane of motion is typically around 180 degrees, allowing the arm to move forward and upward from the side of the body.
How does the range of motion in the shoulder joint change during flexion and extension movements?
During flexion, the shoulder joint allows the arm to move forward and upward, increasing the range of motion. During extension, the shoulder joint allows the arm to move backward and downward, decreasing the range of motion.
How does the deltoid rotation contribute to the range of motion in the shoulder joint?
The deltoid rotation helps the shoulder joint move in different directions, allowing for a wide range of motion.
How does shoulder flexion abduction affect the range of motion in the shoulder joint?
Shoulder flexion and abduction increase the range of motion in the shoulder joint by allowing the arm to move forward and away from the body, respectively. These movements help to improve flexibility and mobility in the shoulder joint.
How can one accurately measure shoulder range of motion?
Shoulder range of motion can be accurately measured by using a goniometer, a tool that measures angles. The person being assessed should move their shoulder in different directions while the goniometer is used to measure the angles of movement. This provides a quantitative measurement of the shoulder's range of motion.
How does the shoulder flexion and extension plane affect range of motion and function in the upper body?
The shoulder flexion and extension plane greatly impact the range of motion and function in the upper body. Flexion allows the arm to move forward and above the head, while extension allows the arm to move backward. These movements are essential for activities like reaching, lifting, and throwing. Limited range of motion in these planes can restrict daily tasks and athletic performance. Strengthening and stretching exercises can help improve flexibility and function in the upper body.
What provides the force to move the arm?
Well it all depends on which motion you want your arm to move but basically the bicept tricept or your shoulder

What is the difference between shoulder abduction and adduction, and how do they affect the range of motion in the shoulder joint?
Shoulder abduction is the movement of the arm away from the body, while shoulder adduction is the movement of the arm towards the body. These movements affect the range of motion in the shoulder joint by allowing the arm to move in different directions, increasing flexibility and overall mobility in the shoulder.
Does the shoulder allow circumduction?
Yes, the shoulder joint does allow circumduction, which is a combination of flexion, extension, abduction, and adduction movements in a circular motion. This range of motion allows the arm to move in multiple directions around a central point, such as when making a windmill motion with the arm.
