A team of researchers is working on a new procedure that could result in the regrowth of neurons in the spinal cord. With which part of the nervous system is the team most concerned?

• A. Peripheral nervous system
• B. Sympathetic nervous system
• C. Parasympathetic nervous system
• D. Central nervous system

Answer: (D)

Verified step by step guidance

1. Identify the main components of the nervous system: the central nervous system (CNS) and the peripheral nervous system (PNS).
2. Understand that the central nervous system consists of the brain and spinal cord, which are crucial for processing information and controlling bodily functions.
3. Recognize that the peripheral nervous system connects the CNS to the rest of the body and is divided into the somatic and autonomic nervous systems.
4. Differentiate between the sympathetic and parasympathetic nervous systems, which are subdivisions of the autonomic nervous system, responsible for 'fight or flight' and 'rest and digest' responses, respectively.
5. Conclude that since the research focuses on neuron regrowth in the spinal cord, the central nervous system is the primary concern, as it includes the spinal cord.
