Which of the following structures is a major component of the spinal cord's gross anatomy?
A
Atria
B
Nephron
C
Alveoli
D
Dorsal root ganglion
Verified step by step guidance1
Understand the question: The problem is asking about a major component of the spinal cord's gross anatomy. The spinal cord is part of the central nervous system and has specific structures associated with it.
Eliminate unrelated options: Analyze the given options. 'Atria' are chambers of the heart, 'Nephron' is the functional unit of the kidney, and 'Alveoli' are air sacs in the lungs. These are not related to the spinal cord.
Focus on the correct option: The 'Dorsal root ganglion' is a cluster of sensory neuron cell bodies located in the dorsal root of a spinal nerve. It is directly associated with the spinal cord and plays a role in transmitting sensory information to the central nervous system.
Relate to gross anatomy: The dorsal root ganglion is visible in the gross anatomy of the spinal cord as a swelling on the dorsal root of each spinal nerve, making it a major component.
Conclude: Based on the above analysis, the dorsal root ganglion is the correct answer as it is a key structure in the spinal cord's anatomy.
