The two components of the autonomic nervous system are the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system is responsible for the "fight or flight" response, preparing the body for stressful situations by increasing heart rate and energy expenditure. In contrast, the parasympathetic nervous system promotes the "rest and digest" state, facilitating relaxation and conservation of energy by slowing the heart rate and enhancing digestion. Together, these systems maintain homeostasis in the body.
PNS means peripheral nervous system. It has two main components: the autonomic nervous system and the somatic, or voluntary nervous system. The autonomic nervous system also contains two parts: the sympathetic nervous system and the parasympathetic nervous system.
The peripheral nervous system is divided into motor and sensory systems. The peripheral nervous system is also divided into the somatic nervous system and the autonomic nervous system.
The autonomic nervous system is responsible for the control of the functions of the internal organs and it has two divisions. These are the sympathetic nervous system and the parasympathetic nervous system.
The Sympathetic and Parasympathetic nervous systems are the divisions of the ANS. The sympathetic is where "fight or flight" comes in, and the parasympathetic is what calms us down afterward -- they work to balance each other.
The two subdivisions of the motor subdivision are the somatic nervous system and the autonomic nervous system. The somatic nervous system transmits action potentials from the CNS to skeletal muscle, and the autonomic nervous system transmits action potentials from the CNS to smooth muscle, cardiac muscle, and glands.
The autonomic nervous system consists of two sub divisions: The sympathetic nervous system and the parasympathetic nervous system.
Involuntary and voluntary actionssomatic nervous system and autonomic nervous system
The PNS can be split into the somatic (voluntary) nervous system and the autonomic (involuntary) nervous system. The autonomic system can be further categorized into the sympathetic division and parasympathetic division.
Involuntary and voluntary actionssomatic nervous system and autonomic nervous system
The two systems that make up the peripheral nervous system are the somatic nervous system and the autonomic nervous system.
Sympathetic and parasympathetic
The nervous system can be divided into two components in several ways. First, you can divide the nervous system into central (brain and spinal cord) and peripheral (the rest of the nerves). Second, you can divide the system into autonomic and voluntary. Third, you can divide the system into sympathetic and parasympathetic.
