Explanation:

Analyze the definition of the nervous system

The nervous system is the body's primary control and communication network. It is responsible for regulating, controlling, and coordinating all physiological activities, both voluntary (like movement) and involuntary (like breathing, digestion, and heartbeat).

Evaluate the given options

• Option A states that it is responsible for controlling and coordinating all of the activities of the body. This is the most comprehensive and accurate definition because "activities" encompasses movement, internal organ functions, sensory processing, and cognitive processes.
• Option B limits the definition to only movement, which excludes sensory functions and autonomic processes.
• Option C uses the word interactions, which is vague and less scientifically precise than "activities."
• Option D limits the definition to synapses, which are merely the microscopic junctions between neurons rather than the macroscopic functions of the body.

Answer:

• (A) The nervous system is responsible for controlling and coordinating all of the activities of the body. (Correct answer)
• (B) The nervous system is responsible for controlling and coordinating all of the movement of the body.
• (C) The nervous system is responsible for controlling and coordinating all the interactions of the body.
• (D) The nervous system is responsible for controlling and coordinating all of the synapses of the body.
