AUTONOMIC NERVOURS SYSTEM

Which of the following is the primary function of the autonomic nervous system (ANS)?

• Control voluntary movements

• Control involuntary functions

• Regulate body temperature

• Control speech production

The autonomic nervous system (ANS) is primarily responsible for regulating:

• Voluntary muscle movements

• Heart rate, digestion, and respiratory rate

• Reflexes and sensory perception

• Conscious thought and memory

The sympathetic nervous system is responsible for which of the following responses?

• Decreased heart rate and blood pressure

• Increased digestion and urination

• "Fight or flight" response, increased heart rate and blood pressure

• Decreased pupil size and muscle relaxation

A patient is experiencing a "fight or flight" response. Which of the following would most likely be seen in this situation?

• Decreased blood sugar levels

• Increased heart rate

• Increased digestive activity

• Constriction of the pupils

Which of the following is true about the parasympathetic nervous system's effect on the digestive system?

• It inhibits the secretion of digestive enzymes.

• It increases gastrointestinal motility.

• It decreases the flow of saliva.

• It reduces peristalsis in the intestines.

The autonomic nervous system controls all of the following except:

• Breathing

• Muscle movement

• Heart rate

• Blood pressure

Which of the following is a characteristic effect of the parasympathetic nervous system?

• Increased heart rate

• Constriction of the bronchioles

• Dilation of the pupils

• Increased blood flow to skeletal muscles
