Answer:
Functions of central nervous system (CNS)
- regulating the sleep cycle
- acting as the control center of the nervous system
Functions of peripheral nervous system:
- managing the body's vital functions
- digesting food for nutrients
- supporting the skeletal system
Step-by-step explanation:
The nervous system is divided into central nervous system (CNS), consisting of the brain and spinal cord and peripheral nervous system (PNS) (cranial and spinal nerves).
The central nervous system commands several functions in the body. The brain is responsible for the perception of different external stimuli through the senses, intelligence and memory.
The peripheral nervous system is organized into plexuses. Its divided into autonomic nervous system and the somatic / sensory nervous system.
- Somatic nervous system: formed by motor fibers that drive CNS impulses to the skeletal muscles. Its main function is to respond to stimuli from the external environment.
- Autonomic Nervous System: the main function is to regulate the internal environment of the body by exercising control over activities such as digestion and excretion. Its divided into 2 systems: sympathetic nervous system (usually stimulates organ function) and parasympathetic nervous system (usually inhibits organ function).
