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.
How do you use continuous passive motion?
Continuous passive motion (CPM) devices are typically used after joint surgery to promote healing and improve range of motion. The device moves the joint through a controlled range of motion continuously, without the need for the patient to actively move the joint. Patients can adjust the speed and range of motion based on their comfort level and rehabilitation goals.
What is the point from which motion can be determined?
The point from which motion can be determined is the reference point, which is used to track the position and movement of an object relative to a fixed location. It serves as a frame of reference for observing and analyzing the motion of objects.
What is the 3 loss of motion?
The three types of loss of motion in joints are contracture (shortening of muscles and tendons around a joint leading to limited range of motion), adhesions (abnormal adherence of tissues limiting normal joint movement), and muscle weakness (lack of strength in muscles supporting a joint leading to instability and restricted movement).
What determines the motion of an object?
The motion of an object is determined by its velocity, acceleration, and the forces acting upon it. Newton's laws of motion describe how these factors interact to determine the motion of an object.
What is used to determine degree of flexion of joints?
The degree of flexion of joints is commonly determined using a goniometer, a specialized instrument that measures the angle of joint movement. The goniometer is placed on the joint, and the angle is read as the joint flexes. Additionally, visual assessment and functional tests may also be used to evaluate joint flexibility and range of motion.
What is the difference between a joint's possible range of motion and its actual range of motion?
The possible range of motion of a joint refers to the full extent of movement that the joint can achieve based on its anatomical structure and design. In contrast, the actual range of motion is the degree to which a joint can move in practice, which may be limited by factors such as muscle tightness, joint stiffness, injury, or pain. Thus, while the possible range indicates potential movement, the actual range reflects real-world limitations.
What is the amount of movement you can make at a joint?
The amount of movement you can make at a joint is determined by the structure of the joint itself, as well as the surrounding muscles and ligaments. Different joints have different ranges of motion, such as hinge joints like the elbow having primarily flexion and extension movement, while ball-and-socket joints like the hip have a wider range of motion including flexion, extension, abduction, adduction, and rotation.
How is the structure of joint electronic warfare coordination cells determined?

What is the range of a human ball and socket?
The range of motion for a ball and socket joint in the human is determined by the depth of the socket. The hip joint has a fairly limited range of motion because the hip socket is deep. In contrast, the shoulder joint has almost 300 degrees of motion because the shoulder socket is shallow.
What is the motion of a ball and socket?
The motion of a ball-and-socket joint allows for a wide range of movement in multiple directions. This type of joint, found in areas like the shoulder and hip, enables rotation, flexion, extension, abduction, and adduction. The spherical head of one bone fits into the concave socket of another, facilitating a full 360-degree motion. This design provides significant versatility and mobility compared to other joint types.
Exercises that put each joint through its full arc of motion are called?
Exercises that put each joint through its full arc of motion are called "full range of motion exercises" or "joint mobility exercises." These exercises help improve flexibility, mobility, and overall joint health by moving the joint through its complete range of movement.
Is a ball and socket joint a uniaxial joint because motion is limited to rotation in a single plane?
No; the ball-and-socket joint is a multi-axial (specifically triaxial) joint because it allows motion in 3 planes.Flexion-extensionAbduction-adductionRotation
The joint in your shoulder is an example of a?
The joint in your shoulder is an example of a ball-and-socket joint, allowing for a wide range of motion in multiple directions.
What is the medical term meaning Excessive joint range of motion?
Hypermobility is the term meaning excessive joint range of motion.
The gliding motion of the wrist is accomplished because of what joint?
plane joint
What does hyperflexed mean?
Hyperflexed refers to a joint or body part being bent to an extreme degree beyond its normal range of motion. This can put strain on the muscles and ligaments surrounding the joint and may increase the risk of injury.
