What are the 2 main divisions of the autonomic nervous system What do each of them do?

The two divisions of the autonomic nervous system are the sympathetic division and the parasympathetic division. The sympathetic system is associated with the fight-or-flight response, and parasympathetic activity is referred to by the epithet of rest and digest.

What are the divisions of the central nervous system?

The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).

What are the two major divisions of the nervous system 1 and 2?

The nervous system as a whole is divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS).

What are the two main divisions of the nervous system How are these divisions subdivided?

The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure 8.2).

What are the 3 divisions of the autonomic nervous system?

The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.

Which are the two main branches of the human nervous system?

The nervous system is broken down into two main divisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The central nervous system includes the brain and the spinal chord. The peripheral nervous system includes all of the nerves outside of the spine and brain.

Is the nervous system divided into three major parts?

The nervous system can be broken down into two major parts-the central nervous system and the peripheral nervous system . The central nervous system, the main data center of the body, includes the brain and spinal cord.

What two parts is the automatic nervous system divided into?

Your autonomic nervous system lies almost entirely outside of the central nervous system and involves two main parts: the craniosacral part (parasympathetic), and the thoracolumbar part (sympathetic). These are sometimes thought of as being opposite to each other, ultimately striking a balance within the body.
