Which system has long preganglionic axons and therefore ganglia that are relatively far from the central nervous system? 1 / 3

• Parasympathetic nervous system
• Somatic nervous system
• Sympathetic nervous system
• Parasympathetic nervous system

We lack awareness of many of our bodies' systems for maintaining homeostasis. The sensations, movements, and secretions of organs such as the heart and intestines are governed by the

• autonomic nervous system
• somatic nervous system
• autonomic nervous system

Autonomic tone refers to

• whether a response is stimulatory or inhibitory
• whether the body's reaction is to fight or flee
• the continual activity maintained by the sympathetic or

parasympathetic divisions

• the degree of tension in skeletal muscles at rest
• the continual activity maintained by the sympathetic or

parasympathetic divisions 2 / 3

Autonomic tone allows for a single division of the autonomic nervous system to control an organ by changing that division's activity levels up or down from the baseline.

• True
• False
• True

Dual innervation means that an individual effector

• may be excited or inhibited by a single division of the

autonomic nervous system

• receives input from both the somatic and the autonomic

nervous system

• receives input from both the sympathetic and the

parasympathetic nervous systems

• receives two autonomic axons on each smooth muscle cell
• receives input from both the sympathetic and the

parasympathetic nervous systems
