What is the name for the ಠpart of the brain that controls basic life-sustaining functions like breathing and heart rate?

Correct Answer: C

Rationale: The medulla oblongata governs vital functions breathing, heart rate in the brainstem. Unlike higher brain regions, it's the autonomic lifeline. Nurses assess it in emergencies like respiratory failure ensuring these basics persist.

Correct Answer: C

Rationale: An organ, like the heart, comprises multiple tissue types (e.g., muscle, connective) working together, unlike a cell (A, single unit), organelle (B, cell part), or macromolecule (D, molecular level). This level of organization follows tissues, integrating diverse functions pumping blood in the heart highlighting anatomy's hierarchical structure.

Correct Answer: A

Rationale: Superior means above (e.g., head superior to chest), unlike inferior (B, below), anterior (C, front), or central (D, middle). In anatomy, this term standardizes spatial relationships in anatomical position, critical for describing locations like the brain superior to the spinal cord making A correct.

Correct Answer: B

Rationale: The knee is distal (farther from trunk) to the thigh, which is proximal (closer). It's not anterior (A, front), lateral (C, side), or proximal. Distal reflects anatomy's limb gradient, positioning the knee below the thigh in standard terms.

Correct Answer: B

Rationale: The axial portion includes head, neck, spine, and ribs, forming the body's core, unlike appendicular (A, limbs), pelvis (C, lower), or trunk (D, torso only). In anatomy, axial structures support central stability, distinguishing them from limb regions.
