What movement increases or decreases the angle between two bones?
Flexion is the act of bringing two bones closer together, decreasing the angle between the two bones. Extension is the act of increasing the angle between two bones, resulting in a straightening motion. What movement does not increase or decrease the angle between bones? Rotation and supination do not increase or decrease the angle between bones.
What is it called when you shorten the distance between bones?
Flexion is the general term for movements that decrease the angle between two bones; however, in the sagittal plane, the special term "adduction" is used for movements that decrease the angle between the limb and the midline. What substance is between your bones? What is a shortened distance between bone is called?
What is the meaning of extension of the limb?
Extension refers to a movement that increases the angle between two body parts. Extension at the elbow is increasing the angle between the ulna and the humerus. Extension of the knee straightens the lower limb. Fig 1 – Flexion and extension.
What is the definition of flexion in anatomy?
The answer is b. Flexion is a body movement term that decreases the angle between two structures, resulting in the structures bending or moving closer together. 2. Which statement describes extension?

What is the term for a body movement that decreases the angle between two structures?
The answer is b. Flexion is a body movement term that decreases the angle between two structures, resulting in the structures bending or moving closer together.
What is the term for the spine that straightens back out?
The answer is b, lateral flexion. As the spine straightens back out, it is called lateral extension.
What is the difference between extension and flexion?
The answer is b, flexion. Flexion usually involves a bending motion, whereas extension is more of a straightening motion.
Which plane of the body is flexion and extension?
The transverse plane. The answer is c, the sagittal plane. Flexion and extension are often taking place within (or parallel to) the sagittal plane. There are some exceptions, however. Flexion and extension of the thumb or lateral flexion and extension of the spine are examples of flexion and extension taking place within the frontal plane.
Which term refers to the movement of the arms anteriorly?
The answer is b, flexion. Flexion sees the arms moving anteriorly, while extension has the arms returning to the anatomical position (or moving posteriorly beyond it).
Which plane does thumb flexion take place in?
Both a and b. The answer is a. Flexion for the thumb has it moving toward the pinky, and the movement takes place within the frontal plane, not the sagittal plane like most other movements of flexion and extension.
What is the movement of the foot around its long axis called?
Inversion and Eversion . Inversion and eversion are movements which occur at the ankle joint, referring to the rotation of the foot around its long axis. Inversion involves the movement of the sole towards the median plane – so that the sole faces in a medial direction.
What is the term for the movement of the fingers around the long axis?
Therefore, abducting the fingers spreads them out. Medial and Lateral Rotation . Medial and lateral rotation describe movement of the limbs around their long axis: Medial rotation is a rotational movement towards the midline. It is sometimes referred to as internal rotation.
What is the movement of the hip called?
Adduction is a movement towards the midline. Adduction of the hip squeezes the legs together.
What is eversion in physics?
Eversion involves the movement of the sole away from the median plane – so that the sole faces in a lateral direction.
What is the movement of the back when lying flat on the back?
This is the supine position, and so this movement is supination. Again, keeping the elbow and shoulder still, flip your hand onto its front, palm down. This is the prone position, and so this movement is named pronation. These terms also apply to the whole body – when lying flat on the back, the body is supine.
How to do supine position?
With your hand resting on a table in front of you, and keeping your shoulder and elbow still, turn your hand onto its back, palm up. This is the supine position, and so this movement is supination. Again, keeping the elbow and shoulder still, flip your hand onto its front, palm down.
What is extension in anatomy?
Extension refers to a movement that increases the angle between two body parts. Extension at the elbow is increasing the angle between the ulna and the humerus. Extension of the knee straightens the lower limb.
What is the term for a body movement that decreases the angle between two structures?
The answer is b. Flexion is a body movement term that decreases the angle between two structures, resulting in the structures bending or moving closer together.
What is the term for the spine that straightens back out?
The answer is b, lateral flexion. As the spine straightens back out, it is called lateral extension.
What is the difference between extension and flexion?
The answer is b, flexion. Flexion usually involves a bending motion, whereas extension is more of a straightening motion.
Which plane of the body is flexion and extension?
The transverse plane. The answer is c, the sagittal plane. Flexion and extension are often taking place within (or parallel to) the sagittal plane. There are some exceptions, however. Flexion and extension of the thumb or lateral flexion and extension of the spine are examples of flexion and extension taking place within the frontal plane.
Which term refers to the movement of the arms anteriorly?
The answer is b, flexion. Flexion sees the arms moving anteriorly, while extension has the arms returning to the anatomical position (or moving posteriorly beyond it).
Which plane does thumb flexion take place in?
Both a and b. The answer is a. Flexion for the thumb has it moving toward the pinky, and the movement takes place within the frontal plane, not the sagittal plane like most other movements of flexion and extension.
