Cuestionario: Fundamentals of Human Anatomy and Movement — 12 preguntas

1. Which description best matches the anatomical position used as the standard reference for body directions and movements?

A. Standing upright, facing forward, with arms at the sides and palms facing forward

B. Standing upright, facing forward, with feet apart and palms facing backward

C. Standing upright, facing sideways, with arms crossed and palms facing inward

D. Lying supine with arms overhead and palms facing up

Answer: (A)

Explicación

Anatomical position is the standard reference stance: the body is upright, facing forward, arms at the sides, and palms face forward. The other options change the reference posture and would alter directional descriptions.

2. Why is the anatomical position important when describing planes, axes, and directional terms?

A. It replaces the need for directional terms

B. It is the only posture in which joints can move correctly

C. It provides a consistent reference stance for all anatomical descriptions

D. It is used only for describing the lower limbs

Answer: (C)

Explicación

The anatomical position is the consistent reference stance used to describe directions, planes, and movements. It does not restrict movement or apply only to one region of the body.

3. Which term describes a structure located closer to the point of attachment on a limb?

A. Proximal

B. Lateral

C. Inferior

D. Distal

Answer: (A)

Explicación

Proximal means closer to the point of attachment, such as the elbow being proximal to the wrist. Distal means farther away from the attachment point.

4. Which pair correctly matches the directional term with its meaning?

A. Anterior means toward the upper limb, and posterior means toward the lower limb

B. Anterior means toward the midline, and posterior means away from it

C. Anterior means toward the head, and posterior means toward the feet

D. Anterior means toward the front, and posterior means toward the back

Answer: (D)

Explicación

Anterior refers to the front of the body, while posterior refers to the back. The other choices confuse these terms with superior/inferior or medial/lateral.

5. Which plane divides the body into left and right parts?

A. Longitudinal axis

B. Frontal plane

C. Transverse plane

D. Sagittal plane

Answer: (D)

Explicación

The sagittal plane divides the body into left and right halves. The frontal plane divides front and back, and the transverse plane divides upper and lower parts.

6. Which axis runs from side to side and is associated with flexion and extension?

A. Transverse axis

B. Longitudinal axis

C. Vertical plane

D. Anteroposterior axis

Answer: (A)

Explicación

The transverse axis runs side-to-side and is used for flexion and extension. The longitudinal axis runs head-to-toe and is linked to rotation.

7. What happens to the angle between bones during flexion?

A. It moves away from the midline

B. It turns around its own axis

C. It increases

D. It decreases

Answer: (D)

Explicación

Flexion decreases the angle between bones. Increasing the angle describes extension, not flexion.

8. Which movement takes a limb away from the body midline?

A. Adduction

B. Circumduction

C. Rotation

D. Abduction

Answer: (D)

Explicación

Abduction moves a body part away from the midline, while adduction moves it toward the midline. Circumduction combines several movements rather than describing a single direction.

9. During a basketball jump shot, which joint action occurs as the player jumps upward?

A. Ankle dorsiflexion

B. Knee extension

C. Elbow flexion

D. Knee flexion

Answer: (B)

Explicación

Knee extension decreases the bend at the knee and occurs as the player jumps. Elbow extension is part of the shooting action, but it is not the main action during takeoff.

10. In the basketball jump shot analysis, which plane mainly describes the knee, hip, and elbow flexion and extension?

A. Sagittal plane

B. Frontal plane

C. Oblique plane

D. Transverse plane

Answer: (A)

Explicación

The jump shot mainly occurs in the sagittal plane for flexion and extension at the knee, hip, and elbow. Frontal plane movements are associated with abduction and adduction instead.

11. Which plane and axis are used to describe a cartwheel in this material?

A. Transverse plane and longitudinal axis

B. Sagittal plane and transverse axis

C. Sagittal plane and anteroposterior axis

D. Frontal plane and anteroposterior axis

Answer: (D)

Explicación

A cartwheel is identified as occurring in the frontal plane and rotating around the anteroposterior axis. The sagittal and transverse combinations describe different movements.

12. Which sporting action is a clear example of plantar flexion in this material?

A. A sprinter pushing off the starting blocks

B. A shooter straightening the elbow during release

C. A gymnast lowering into a squat

D. A runner bending the knee before takeoff

Answer: (A)

Explicación

Plantar flexion means pointing the toes downward, and pushing off the starting blocks uses that action. The other options describe elbow or knee flexion/extension rather than ankle plantar flexion.
