Question

question 28 (1 point)
the skin is ___ to the bones.
○ superficial
○ distal
○ proximal
○ anterior

question 29 (1 point)
the pericardial cavity is ___ to the pleural cavity
○ medial
○ sagittal
○ inferior
○ deep

Explanation:

Question 28

To solve this, we analyze anatomical directional terms:

• "Superficial" means closer to the surface. Skin is on the surface, bones are deeper, so skin is superficial to bones.
• "Distal" refers to farther from the point of attachment (e.g., fingers are distal to the elbow), not applicable here.
• "Proximal" is closer to the point of attachment, not for skin - bone relation.
• "Anterior" means front, not about depth/position relative to bones' depth.

Analyzing anatomical directional terms:

• "Medial" means closer to the midline of the body. The pericardial cavity (around the heart) is closer to the midline than the pleural cavities (around the lungs), so it is medial to the pleural cavity.
• "Sagittal" is a plane, not a directional term for position between cavities.
• "Inferior" means below, not relevant for this cavity - to - cavity relation.
• "Deep" is about depth, but the pericardial cavity is not deeper than the pleural cavity in this context.

Answer:

A. Superficial
