Chapter 3: Problem 10

If your ________ is activated, you will feel relatively at ease. a. somatic nervous system b. sympathetic nervous system c. parasympathetic nervous system d. spinal cord

Short Answer

Expert verified
c. parasympathetic nervous system

Step by step solution

01

Understanding the Somatic Nervous System

The somatic nervous system is responsible for carrying sensory and motor information to and from the central nervous system. This primarily involves control of muscle movements and responses to sensations of touch and pain. Activation of this system does not necessarily lead to feelings of ease.
02

Understanding the Sympathetic Nervous System

The sympathetic nervous system is part of the autonomic nervous system which controls the body's responses to perceived threats. It is responsible for the 'fight or flight' response which triggers increased heart rate, blood pressure, and blood glucose levels. Activation of this system would not cause feelings of ease, but rather stress and heightened alertness.
03

Understanding the Parasympathetic Nervous System

The parasympathetic nervous system is another part of the autonomic nervous system, working to calm the body down and conserve energy after the 'fight or flight' response. This system reduces heart rate and blood pressure while promoting rest, digestion, and energy storage. Activation of this system would result in a state of ease and calm.
04

Understanding the Spinal Cord

The spinal cord is the major conduit for transmitting information between the brain and the rest of the body. It does not independently control any autonomic functions or emotional states.
