The cerebral cortex, particularly the frontal lobe, provides emotional input and is involved in the overall integration of the ANS.

Question 2

Answer 2

The brain stem regulates vital functions such as pupil size, heart rate, blood pressure, airflow, and salivation.

Question 3

Identify the functions regulated by the brain stem in the ANS.

Answer 3

The brain stem regulates pupil size, heart rate, blood pressure, airflow, and salivation.

Question 4

Do spinal cord reflexes play a role in the autonomic nervous system?

Answer 4

Yes, the spinal cord is responsible for reflexes related to urination, defecation, erection, and ejaculation.

Question 5

Answer 5

The overall integration of the ANS is primarily managed by the cerebral cortex, which acts as the ‘boss’ of the system.
