Psychology 101 Section 1: Nervous System Quiz

Study Notes

Nervous System Overview

The nervous system is a complex communication network in the body, allowing for rapid responses and coordination of activities.
It comprises all nerve cells within both the peripheral and central systems.

Peripheral Nervous System (PNS)

The PNS consists of sensory and motor neurons, linking the central nervous system to the body's extremities and organs.
It facilitates communication between the brain/spinal cord and the rest of the body.

Central Nervous System (CNS)

The CNS is made up solely of the brain and spinal cord, serving as the main processing center for information and decision-making.

Autonomic Nervous System (ANS)

Part of the PNS, the ANS regulates involuntary functions such as digestion and heart rate, influencing internal organ activities.

Somatic Nervous System

The somatic nervous system is a division of the PNS responsible for voluntary muscle movements, overseeing the body's skeletal muscles.
Referred to as the skeletal nervous system, it enables conscious control of movement.

Sympathetic Nervous System

This division of the ANS prepares the body for high-energy activities, triggering the fight-or-flight response.
It mobilizes energy reserves to face perceived threats or stressors.

Parasympathetic Nervous System

Opposite to the sympathetic system, the parasympathetic division promotes relaxation and restorative processes within the body.
It conserves energy by slowing heart rate, enhancing digestion, and supporting other functions essential for recovery.
