Question 1

Which of the following limb movements occur during "jumping jacks"?

Accepted Answer

Jumping jacks involve moving the limbs away from the body's midline (abduction) and then back towards the midline (adduction).

Question 2

Which of the following categories of motion is mutually exclusive with each of the others?

Accepted Answer

Rotational motion involves rotation around an axis, while translational, rectilinear, and curvilinear motion involve movement in a straight line or a curved path without rotation. Therefore, rotational motion is mutually exclusive with each of the other types of motion.

Question 3

In which of the following planes does a forward roll occur?

Accepted Answer

A forward roll involves flexion and extension of the spine, which occurs in the sagittal plane.

Question 4

Movements in the transverse plane occur around which axis?

Accepted Answer

Movements in the transverse plane occur around the longitudinal axis, which runs from the head to the feet, allowing for rotational movements.

Question 5

Elbow extension takes place in what plane?

Accepted Answer

Elbow extension involves movement in the sagittal plane, which is the plane that divides the body into left and right portions. This movement occurs when the forearm moves away from the upper arm, increasing the angle between these two body parts.

Question 6

A dancer performs a pirouette in which plane?

Accepted Answer

A pirouette is a spinning movement in which the body rotates around a vertical axis. This axis passes through the body from top to bottom, dividing it into two halves - upper and lower. The rotation occurs in the transverse plane, which is perpendicular to the vertical axis. Therefore, the correct answer is C, transverse.

Question 7

Abduction occurs in which plane?

Accepted Answer

Abduction occurs in the frontal plane, as it involves movement away from the midline of the body. Sagittal plane involves flexion and extension, while transverse plane involves rotation. The answer is not D as abduction always occurs in the frontal plane regardless of the action being performed.

Question 8

Nodding the head "yes" occurs in which plane?

Accepted Answer

Nodding the head "yes" involves movement along the sagittal plane, which divides the body into left and right halves. The movement involves flexion and extension of the neck, with the head moving forward and downward (flexion) and then backward and upward (extension) in a linear motion along the sagittal plane.

Question 9

Which of the following are transverse plane movements at the shoulder?

Accepted Answer

Transverse plane movements at the shoulder are those that occur in the plane that divides the body into upper and lower halves. Horizontal abduction and medial rotation both occur in this plane.

Question 10

Which of the following statements is false?

Accepted Answer

The hip is proximal (closer to the center of the body) to the knee.

Question 11

Which of the following motions occurs primarily in the sagittal plane?

Accepted Answer

Running primarily involves movement in the sagittal plane, as the legs move forward and backward. A cartwheel and pirouette involve movements in multiple planes, including the sagittal plane, but also involve motion in the frontal and transverse planes.

Question 12

During the preparatory phase for an underhand softball pitch, the hand holding the ball is drawn behind the body prior to the forward swing of the arm. When the hand is drawn behind the body, which of the following movements occurs at the shoulder?

Accepted Answer

When the hand holding the ball is drawn behind the body during the preparatory phase for an underhand softball pitch, the movement at the shoulder is hyperextension. This is because hyperextension refers to the extension of a limb or part beyond the normal limit or range of motion, which occurs when the arm is moved behind the body.

Question 13

The cardinal frontal plane divides the body into equal _____.

Accepted Answer

The answer of The cardinal frontal plane divides the body...

Question 14

Abduction takes place around which axis?

Accepted Answer

Abduction occurs around the anteroposterior axis, which allows movement away from the midline of the body in the frontal plane.

Question 15

Primarily in which plane does the swinging of a baseball bat occur?

Accepted Answer

The swinging of a baseball bat primarily occurs in the transverse plane, which involves rotational movements around a vertical axis.

Question 16

Which of the following terms best describes translational motion along a curved line?

Accepted Answer

Translational motion along a curved line is best described as curvilinear, as it involves movement along a curved path rather than a straight line (rectilinear) or rotation around an axis (rotational). "General" is too broad and does not specifically describe the type of motion involved.

Question 17

Most human movement falls into which category?

Accepted Answer

The answer of Most human movement falls into which category?
...

Question 18

Which of the following is not an example of a sagittal plane movement?

Accepted Answer

Lateral flexion occurs in the frontal plane, not the sagittal plane. Movements in the sagittal plane include flexion, hyperextension, and plantar flexion, which involve moving the body parts forward or backward.

Question 19

Which imaginary cardinal plane bisects the body into right and left halves?

Accepted Answer

The sagittal plane is a vertical imaginary plane that runs from the head to the feet, passing through the midline of the body and dividing it into left and right halves. Therefore, it is the correct choice for the given question. The frontal plane (B) divides the body into front and back halves, and the transverse plane (C) divides the body into upper and lower halves.

Question 20

Which of the following motions occurs primarily in the frontal plane?

Accepted Answer

The cartwheel occurs primarily in the frontal plane, which involves movements of abduction and adduction, as well as lateral flexion. Running involves movements in the sagittal plane, while pirouette primarily involves rotation in the transverse plane.
