Question

Which of the following best defines the nervous system?

a. The nervous system is responsible for controlling and coordinating all of the activities of the body.
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.

Answer 1

The best definition of the nervous system is that it is responsible for controlling and coordinating all of the activities of the body, involving both voluntary and involuntary functions through the central and peripheral nervous systems with localized specialized functions.

Step-by-step explanation:

The nervous system is an intricate network responsible for managing an organism's myriad functions. Based on the options provided and the information regarding its functions, the statement that best defines the nervous system is: 'The nervous system is responsible for controlling and coordinating all of the activities of the body.' This encompasses all forms of control and coordination, whether it be the somatic (voluntary) functions like moving your arm, or autonomic (involuntary) functions, such as breathing and heart rate regulation.

The nervous system operates through a balanced and synchronized combination of electrical and chemical signaling. With structures such as the brain and spinal cord (central nervous system), and nerves spreading throughout the body (peripheral nervous system), it plays a critical role in piloting both conscious actions and subconscious mechanisms.

Key to its functionality is the concept of localization of function, where certain areas are specialized for specific tasks. This aspect allows for the high degree of complexity and precision in the tasks the nervous system performs, controlling everything from the simple reflexes to complex cognitive processes that define human thought and behavior.

Answer 2

d. The nervous system is responsible for controlling and coordinating all of the synapses of the body.

The nervous system has three general functions: a sensory function, an interpretative function and a motor function. 1. Sensory nerves gather information from inside the body and the outside environment. The nerves then carry the information to the central nervous system (CNS). 2. Sensory information brought to the CNS is processed and interpreted. 3. Motor nerve cells convey information from the CNS to the muscles and glands of the body. The nervous system is responsible for coordinating all of the body's activities.
