During a stress-inducing simulation, researchers observe increased heart rate and sweating in participants. These automatic responses are best explained by activity in the:

• Endocrine system

• Somatic nervous system

• Autonomic nervous system

• Reticular activating system

Which division of the nervous system arouses the body and mobilizes its energy in stressful situations?

• Somatic nervous system

• Parasympathetic nervous system

• Central nervous system

• Sympathetic nervous system

The division of the autonomic nervous system that arouses the body, mobilizing its energy, is called the:

• Parasympathetic nervous system

• Sympathetic nervous system

• Peripheral nervous system

• Somatic nervous system

A psychologist observes that when subjects hear a loud noise, their pupils dilate, heart rate increases, and digestion slows. These physiological changes indicate activation of which system?

• Parasympathetic nervous system

• Endocrine system

• Sympathetic nervous system

• Somatic nervous system

After experiencing a mock robbery simulation, participants show elevated breathing and increased heart rate for several minutes. These reactions are most directly triggered by the:

• Parasympathetic nervous system

• Reticular formation

• Sympathetic nervous system

• Cerebral cortex

Which part of the autonomic nervous system conserves energy and calms the body?

• Somatic nervous system

• Parasympathetic nervous system

• Central nervous system

• Sympathetic nervous system

The division of the autonomic nervous system that calms the body and conserves its energy is the:

• Parasympathetic nervous system

• Sympathetic nervous system

• Somatic nervous system

• Skeletal nervous system

Following a test, a student begins to relax, their heartbeat slows, and breathing becomes steady. Which system is most active at this time?

• Sympathetic nervous system

• Somatic nervous system

• Parasympathetic nervous system

• Endocrine system

A therapy patient practices breathing techniques and visualization to lower heart rate and restore calm after anxiety. Which system supports this calming effect?

• Sympathetic nervous system

• Central nervous system

• Parasympathetic nervous system

• Limbic system

What term identifies the basic building block of the nervous system, responsible for transmitting messages?

• Axon

• Neuron

• Glial cell

• Dendrite
