The autonomic nervous system, which consists of the sympathetic and parasympathetic divisions, carries messages about the involuntary activities of your body. Specifically, the vagus nerve is a key component that regulates functions such as heart rate, digestion, and respiratory rate. Additionally, other nerves in the autonomic system also transmit signals to control bodily functions that occur without conscious control. Together, these nerves ensure the body's internal environment remains stable and responsive to changes.

The nerves that originate in the brain and carry messages to and from structures in the head and neck are known as cranial nerves. There are 12 pairs of cranial nerves, each with specific functions related to sensory and motor control in the head and neck region. These nerves play crucial roles in activities such as vision, hearing, taste, and facial movements.
Motor neurons.
The nervous system carries messages to and from the brain through a network of neurons. Sensory neurons carry information from the body to the brain, while motor neurons carry signals from the brain to the body to control movement and other functions.
True. Sensory nerves carry messages from the sensory organs (such as skin, eyes, ears, nose, and tongue) to the brain, enabling us to perceive and interpret different stimuli from the environment.
