Multiple Choice

A lab assistant is tasked with finding the sympathetic trunks. Where should he be looking?

Inside the cardiac muscle tissue

Alongside the vertebral column in the thoracic and lumbar regions

Embedded in the walls of the small intestine

Within the cerebral cortex of the brain

Verified step by step guidance

Understand the role and location of the sympathetic trunks: The sympathetic trunks are part of the autonomic nervous system, specifically the sympathetic division. They consist of paired chains of ganglia that run parallel to the vertebral column.

Recall the anatomical regions associated with the sympathetic trunks: These structures are located alongside the vertebral column, primarily in the thoracic and lumbar regions. They are not found in cardiac muscle tissue, the walls of the small intestine, or the cerebral cortex.

Eliminate incorrect options based on anatomical knowledge: Cardiac muscle tissue is part of the heart and does not house the sympathetic trunks. The walls of the small intestine are part of the digestive system and contain enteric nervous system components, not sympathetic trunks. The cerebral cortex is part of the brain and is involved in higher-order functions, not autonomic nervous system pathways.

Focus on the correct anatomical location: The sympathetic trunks are positioned alongside the vertebral column, specifically in the thoracic and lumbar regions. This location allows them to connect with spinal nerves and distribute sympathetic signals throughout the body.

Conclude the reasoning process: Based on the anatomical and physiological context, the lab assistant should look for the sympathetic trunks alongside the vertebral column in the thoracic and lumbar regions.
