If a medical image displays internal anatomy in mid-sagittal section, which of the following describes the section?

Correct Answer: A

Rationale: A mid-sagittal section splits the body vertically through the midline nose to navel into equal right and left halves. Nurses use this in imaging like MRI to view symmetrical structures, unlike horizontal or off-center cuts. It's a critical perspective for assessing bilateral anatomy and guiding precise interventions.

Correct Answer: D

Rationale: The cervical region is the neck, anatomically between the head and thorax (chest). The lumbar region is the lower back, throat is vague, and torso spans chest to pelvis none fit precisely. In anatomical terms, cervical vertebrae (CA-C7) define this transition, critical for nerve and vessel passage (e.g., carotid artery), making D the most appropriate term.

Correct Answer: B

Rationale: Structure determines function e.g., the heart's muscular walls (structure) enable pumping (function). Negative feedback regulates, not defines, this link. It's always relevant (C, D false). Anatomically, this principle is foundational: lung alveoli's thinness aids gas exchange, kidney tubules filter blood B captures this universal relationship.

Correct Answer: A

Rationale: The foot is distal to the thigh (femur); the hand is distal to the brachium (A, upper arm), not shoulder, palm (C, hand part), or digits. Anatomically, this analogy tracks limb segments hand below elbow mirrors foot below knee making A apt.

Correct Answer: C

Rationale: A transverse plane cuts horizontally, showing trachea, esophagus, muscles, and vertebra in cross-section at neck level, unlike sagittal (A, E, left-right), coronal (B, front-back), or vague vertical. Anatomically, this reveals spatial relationships e.g., trachea anterior to vertebra ideal for imaging, confirming C.
