What term describes the straightening of a joint rather than the bending?

Extension straightens a joint, and hyperextension bends it but in the opposite direction from flexion. … Hyperextension straightens a joint, and extension bends it in the opposite direction from flexion.

Which term means bending or decreasing the angle at a joint?

flexion
In the limbs, flexion decreases the angle between the bones (bending of the joint), while extension increases the angle and straightens the joint.

Which of the following best describes the strategy for increasing a specific joint range of motion?

Which of the following describes the BEST strategy for increasing a specific joint’s range of motion? … Applying the principles of overload and progression to exercise the joint.

What is range of motion need to be measured separately for each joint?

The range of motion for each joint needs to be measured separately as each joint has a different range of motion depending on the type and placement of the joint, for instance ball and socket joints have more movement than a hinge joint.

What is the straightening movement of muscles at a joint?

Extension. The opposite of flexion is extension, which refers to the straightening of a joint. In other words, flexion works to shorten a joint angle while extension works to increases it.

What is straightening the lower leg away from the upper leg?

Moving a body part toward the midline. … Moving the arm away from the side of the body. abduction. Straightening the lower leg away from the upper leg.

Which of the following terms describes the straightening of a joint rather than bending quizlet?

Extension straightens a joint, and hyperextension bends it but in the opposite direction from flexion.

Why does range of motion need to be measured separately for each?

The cup shape of the socket allows for nearly circular motion. Why does range of motion need to be measured separately for each joint? … Range of motion can change rapidly in a joint.

Why do we measure range of motion?

Range of motion, also known as ROM, is a measure of flexibility involving ligaments, tendons, muscles, bones, and joints, so testing for ROM is essential in determining fitness and in assessing possible damage.

Does hyperextension bends a joint in the opposite direction as flexion?

Hyperextension straightens a joint, and extension bends it in the opposite direction from flexion. … Extension straightens a joint, and hyperextension bends it but in the opposite direction from flexion.

Is the thumb the only saddle joint?

Synovial joints have the greatest range of flexibility and motion. … The thumb is the only saddle joint in the human body.

Why synovial joints have greater flexibility than fixed and cartilaginous joint?

Explain why synovial joints have greater flexibility than fixed and cartilaginous joint. Unlike fixed joints or cartilaginous joints, where the bones are connected by either connective tissue or cartilage, the bones in synovial joints are not directly joined by anything, which allows for a much greater range of motion.

Why do ball-and-socket joints have the greatest range of motion?

Ball-and-socket joints possess a rounded, ball-like end of one bone fitting into a cup-like socket of another bone. This organization allows the greatest range of motion, as all movement types are possible in all directions.

Which joints have greater range of motion?

1. Ball and Socket Joints: These joints allow for the greatest range of motion. The joint involves a ball fitting into a concave surface. Because these joints allow for more motion, they are at greater risk for instability.

Which type of joint allows rotation of one bone around another like when rotating the head?

pivot joint
A pivot joint allows one bone to rotate around another. An example of a pivot joint is the joint between the first two vertebrae in the spine. This joint allows the head to rotate from left to right and back again. A hinge joint allows back and forth movement like the hinge of a door.

What movements occur at a ball and socket joint?

Ball and socket joints also allow types of movement called abduction, adduction, rotation and circumduction. Abduction – movement away from the midline of the body. This occurs at the hip and shoulder joints during a jumping jack movement. Adduction – movement towards the midline of the body.

Which of the following is a ball and socket joint?

The shoulder joint is a ball-and-socket joint.

What type of joint is a ball and socket joint quizlet?

Ball-and-socket joints. These are the shoulder and hip joints—the only multiaxial joints in the body. In both cases, one bone (the humerus or femur) has a smooth hemispherical head that fits into a cuplike socket on the other (the glenoid cavity of the scapula or the acetabulum of the hip bone.
