Question

A spinal cord injury disrupts

• A. Reflex action
• B. Endocrine action
• C. Excretory action
• D. Cellular respiration

Answer 1

The correct option is A Reflex action

The spinal cord functions primarily in the transmission of neural signals between the brain and the rest of the body but also contains neural circuits that can independently control numerous reflexes and central pattern generators.
The spinal cord is an important component of CNS. It serves as a two-way conduction path between the peripheral nervous system and brain. The controlling centres in different areas of spinal cord function as reflex centres which control all the spinal reflexes. An injury to the spinal cord will disrupt the reflexes. The part of the body affected will depend on upon the region where the spinal cord is injured. It may be the neck, thoracic or abdominal region.

Therefore, the correct answer is option A.
