Question

For each part of the nervous system listed below, write about how it functions and give an example of how it functions in everyday life.

Peripheral nervous system
Central nervous system
Autonomic nervous system
Somatic nervous system
Sympathetic nervous system
Parasympathetic nervous system

Answer 1

• Autonomic nervous system controls our internal organs and glands

1. Central nervous system (CNS) brain and spinal cord.

• fight or flight response activation of the sympathetic division of the autonomic nervous system, allowing access to energy reserves and heightened sensory capacity so that we might fight off a given threat or run away to safety
• homeostasis state of equilibrium—biological conditions, such as body temperature, are maintained at optimal levels
• parasympathetic nervous system associated with routine, day-to-day operations of the body
• peripheral nervous system (PNS) connects the brain and spinal cord to the muscles, organs and senses in the periphery of the body
• somatic nervous system relays sensory and motor information to and from the CNS
• sympathetic nervous system involved in stress-related activities and functions
