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
Why is it possible to swing around the leg in circles at the hip joint but not at the knee joint?
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.
What is the type of joint for turning movements?
The type of joint that allows for turning movements is called a pivot joint. An example of a pivot joint is the atlantoaxial joint between the first and second cervical vertebrae, which enables the head to rotate. Another example is the proximal radioulnar joint, which allows for the rotation of the forearm. These joints facilitate rotational motion around a single axis.
What is The range of motion around specific joints is?
The range of motion (ROM) around specific joints refers to the extent to which a joint can move in various directions, typically measured in degrees. It varies by joint type; for example, the shoulder joint has a greater ROM than the knee joint. Factors influencing ROM include joint structure, surrounding muscles and ligaments, age, and activity level. Maintaining flexibility and strength through regular exercise can help preserve or improve the range of motion in joints.
What is the plane of motion for the glenohumeral joint?
The glenohumeral joint moves in multiple planes of motion, including flexion/extension, abduction/adduction, and internal/external rotation. This allows for a wide range of movement in the shoulder joint.
Why would weakness of ligaments lead to a greater range of motion of a joint?
there is a defect in the collagen tissue which allows for more ROM. if the collagen was not defective it would be more elastic and not allow a greater ROM range of movement
How does the radius and ulna twist affect the range of motion in the wrist joint?
The twisting of the radius and ulna bones in the forearm allows for a greater range of motion in the wrist joint. This twisting motion enables the wrist to move in multiple directions, such as flexion, extension, and rotation, increasing the overall flexibility and functionality of the wrist joint.

Name one joint?
The shoulder joint. It is a ball-and-socket joint that allows for a wide range of motion in the arm.
Why would weakness of ligaments lead to greater range of motion at a joint?
there is a defect in the collagen tissue which allows for more ROM. if the collagen was not defective it would be more elastic and not allow a greater ROM range of movement
Why is it possible to swing around the leg in circles at the hip joint but not at the knee joint?
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.
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.
What is the type of joint for turning movements?
The type of joint that allows for turning movements is called a pivot joint. An example of a pivot joint is the atlantoaxial joint between the first and second cervical vertebrae, which enables the head to rotate.

What is the type of join that used for back and forth movements?
A pivot joint allows for back and forth movements in a rotating motion. It is a type of synovial joint that permits rotation around a single axis.
Does the hip joint allow a greater freedom of movement than the shoulder joint?
No, the shoulder joint allows a greater freedom of movement than the hip joint. The shoulder joint is a ball-and-socket joint, allowing for a wider range of motion compared to the hip joint, which is a ball-and-socket joint with more restricted movements due to its stronger and more stable structure.
What is the plane of motion for the glenohumeral joint?
The glenohumeral joint moves in multiple planes of motion, including flexion/extension, abduction/adduction, and internal/external rotation. This allows for a wide range of movement in the shoulder joint.
