Cerebrum is related to the brain in the same way as _______ is related to the digestive system.

Appeared in: AIIMS Nagpur NO - 2018

Explanation

  • The question presents an analogy based on a 'part-to-whole' relationship.
  • The cerebrum is a major structural and functional part of the brain, which is the central organ of the nervous system.
  • Similarly, the esophagus is a major structural and functional organ within the digestive system, connecting the pharynx to the stomach.
  • Therefore, the relationship 'Esophagus is to Digestive System' correctly mirrors the relationship 'Cerebrum is to Brain'.

Why Other Options Were Wrong

  • Option A: A neuron is a microscopic nerve cell, which is a fundamental unit of the nervous system, not a large organ part like the cerebrum.
  • Option B: A vertebrate is a classification of animal (an animal with a spine). It is not an anatomical part of an organ system.
  • Option D: Hemoglobin is a protein molecule found in red blood cells. It belongs to the circulatory system and is involved in oxygen transport, not digestion.

Visual explanation — Related Visual
  • Visual 1: Diagram - A labeled diagram of the human brain, clearly showing the location and relative size of the cerebrum compared to the cerebellum and brainstem. This helps visualize the 'part-to-whole' relationship.
  • Visual 2: Diagram - A labeled diagram of the human digestive system, highlighting the esophagus and its position connecting the pharynx to the stomach. This provides the corresponding visual for the correct answer.
Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Analogical reasoning based on anatomical relationships as background academic context rather than a clinical decision trigger.
  • Understanding organ systems is fundamental to nursing. Knowing which organ belongs to which system helps in assessing, diagnosing, and managing patient conditions.
  • For example, a patient with a stroke might have damage to the cerebrum, leading to motor or sensory deficits. A patient with difficulty swallowing (dysphagia) may have an issue with their esophagus.
  • Recognizing these relationships allows nurses to anticipate symptoms and plan care effectively based on the affected system.
How to Approach the Question
  • First, identify the relationship between the first pair of words: 'Cerebrum' and 'Brain'.
  • Recognize that the cerebrum is a major part of the brain. The relationship is 'part to whole'.
  • Next, apply this 'part-to-whole' relationship to the second part of the analogy: '_______ is to digestive system'.
  • Evaluate each option to see which one is a major part of the digestive system.
  • Eliminate options that are not organs of the digestive system (Neuron, Vertebrate, Hemoglobin).
  • Select the option that correctly fits the analogy (Esophagus).
Concept Tested & Keywords
