Which of the following exercises would take place in the sagittal plane?
- A.
Bicep curls
- B.
Side bends
- C.
Lateral raises
- D.
Oblique cycles
Correct Answer
A. Bicep curlsExplanation
Bicep curls would take place in the sagittal plane because this exercise involves flexion and extension of the elbow joint, which occurs in the same plane as the sagittal plane. The sagittal plane divides the body into left and right halves, and movements in this plane occur along the anterior-posterior axis. Bicep curls involve moving the forearm towards the upper arm (flexion) and then returning it to the starting position (extension), both of which occur in the sagittal plane.Rate this question:

Which exercise uses movement in the frontal plane?
- A.
Lateral raises
- B.
Oblique cycles
- C.
Pec dec
- D.
Tricep extension
Correct Answer
A. Lateral raisesExplanation
Lateral raises are an exercise that uses movement in the frontal plane. This exercise involves raising the arms out to the sides, targeting the lateral deltoid muscles. The frontal plane divides the body into front and back halves, and movement in this plane involves side-to-side motions. Lateral raises specifically target the muscles responsible for shoulder abduction, which is the movement of the arms away from the body in a sideways direction. Therefore, lateral raises are the correct answer as they involve movement in the frontal plane.Rate this question:

Which of the following joint actions take place in the transverse plane?
- A.
Rotation
- B.
Extension
- C.
Abduction
- D.
Lateral flexion
Correct Answer
A. RotationExplanation
Rotation is the joint action that takes place in the transverse plane. In this plane, movement occurs around an imaginary axis running horizontally from left to right. Rotation refers to the movement of a body part turning or twisting around its own axis. This can be seen, for example, when rotating the head from side to side or when rotating the forearm to turn the palm up or down. Extension, abduction, and lateral flexion occur in different planes of movement and are not specific to the transverse plane.Rate this question:

Which of the following exercises take place in the transverse plane?
- A.
Oblique cycles
- B.
Side bends
- C.
Tricep dips
- D.
Squats
Correct Answer
A. Oblique cyclesExplanation
Oblique cycles take place in the transverse plane because they involve rotational movements of the torso. The transverse plane divides the body into upper and lower halves and movements in this plane involve rotation around the vertical axis. Oblique cycles specifically target the oblique muscles, which are responsible for rotating and stabilizing the torso. Therefore, oblique cycles are the exercise in the given options that occur in the transverse plane.Rate this question:

Which joint action involves the turning of the palm upwards?
- A.
Supination
- B.
Pronation
- C.
Inversion
- D.
Eversion
Correct Answer
A. SupinationExplanation
Supination is the joint action that involves the turning of the palm upwards. This movement is commonly observed when holding a bowl of soup or when performing a bicep curl. During supination, the radius and ulna bones in the forearm rotate to allow the palm to face upwards. This action is opposite to pronation, which involves the turning of the palm downwards. Inversion and eversion, on the other hand, refer to movements of the foot and ankle, not the palm.Rate this question:

Horizontal flexion and extension occur in which plane?
- A.
Transverse
- B.
Frontal
- C.
Sagittal
- D.
Coronal
Correct Answer
A. TransverseExplanation
Horizontal flexion and extension occur in the Transverse plane. The Transverse plane divides the body into upper and lower halves, and movements in this plane involve rotation around a vertical axis. Horizontal flexion refers to bringing a body part forward in the horizontal plane, while horizontal extension refers to moving it backward. Therefore, these movements occur in the Transverse plane.Rate this question:

Which of the following joint actions involve pointing the toe down?
- A.
Plantar-flexion
- B.
Dorsi-flexion
- C.
Opposition
- D.
Inversion
Correct Answer
A. Plantar-flexionExplanation
Plantar-flexion involves pointing the toe down. This joint action occurs when the foot is flexed downward, such as when standing on tiptoes or pressing the gas pedal in a car. Dorsi-flexion, on the other hand, involves pulling the toe up towards the shin. Opposition refers to the movement of the thumb across the palm to touch the fingers, while inversion involves turning the sole of the foot inward.

Which movement is not possible at the thumb/first metacarpal?
- A.
Rotation
- B.
Adduction
- C.
Flexion
- D.
Circumduction
Correct Answer
A. RotationExplanation
Rotation is not possible at the thumb/first metacarpal because the thumb joint, known as the carpometacarpal joint, is a saddle joint that allows for flexion, extension, abduction, adduction, and opposition movements. However, rotation is not a movement that can be performed at this joint.Rate this question:
