1. The coronal plane of the body may also be called the ___________ plane.

• A. sagittal
• B. median
• C. frontal
• D. axial

Correct answer: C

Rationale: The correct answer is C: frontal. The coronal plane of the body is also known as the frontal plane. This plane divides the body into front (anterior) and back (posterior) sections. It is perpendicular to the sagittal plane and divides the body into front and back portions. The term 'coronal' is often used in radiology and anatomy to describe this specific anatomical plane. Choices A, B, and D are incorrect because the sagittal plane divides the body into left and right portions, the median plane is another name for the sagittal plane, and the axial plane is a term less commonly used to describe an anatomical plane.

2. Which type of muscle tissue is under voluntary control?

• A. Smooth muscle
• B. Cardiac muscle
• C. Skeletal muscle
• D. Cardiac muscle

Correct answer: C

Rationale: Skeletal muscle is under voluntary control, allowing conscious regulation for activities like walking and lifting. This type of muscle is attached to bones and is responsible for movement in the body. Smooth muscle (Choice A) is involuntary and found in organs like the stomach and intestines. Cardiac muscle (Choice B and D) is also involuntary and specific to the heart, contracting rhythmically to pump blood, but it is not under conscious control.

3. In the human body, the ribs are ___________ to the lungs.

• A. medial
• B. superior
• C. anterior
• D. deep

Correct answer: C

Rationale: The correct answer is 'C: anterior.' The term 'anterior' refers to a position in front of or toward the front of the body. In this case, the ribs are positioned in front of the lungs when considering the anatomical position. The term 'medial' means toward the midline of the body, 'superior' means above or higher in position, and 'deep' refers to a position farther from the surface or external part. Therefore, the most appropriate choice is 'anterior' when describing the relationship between the ribs and the lungs.

4. Which type of joint allows for rotational movement?

• A. Hinge joint
• B. Pivot joint
• C. Ball and socket joint
• D. Saddle joint

Correct answer: B

Rationale: A pivot joint, such as the one found in the neck, allows for rotational movement, enabling the head to turn from side to side. This type of joint provides a specific axis of rotation, allowing for a turning motion around that axis. Choice A, the hinge joint, primarily allows movement in one plane, like the elbow joint's flexion and extension. Choice C, the ball and socket joint, allows for a wide range of motion in multiple directions, but it is not primarily known for rotational movement. Choice D, the saddle joint, allows for movements like bending, straightening, and limited rotation, but it is not primarily designed for rotational movement like the pivot joint.

5. The dorsal body cavity is _______ to the ventral body cavity.

• A. medial
• B. deep
• C. posterior
• D. anterior

Correct answer: C

Rationale: The dorsal body cavity is positioned on the back (posterior) side of the body, whereas the ventral body cavity is on the front (anterior) side. Therefore, the dorsal body cavity is posterior to the ventral body cavity. Choice A, 'medial,' refers to a position toward the midline, not the back or front. Choice B, 'deep,' is a term used to describe structures that are further away from the surface, not their position in relation to each other. Choice D, 'anterior,' is the opposite of 'posterior' and refers to the front side of the body, not the back.
