Which of the following statements correctly differentiate between sympathetic and parasympathetic nervous systems?
Options:
Answer:
Solution:
The sympathetic nervous system prepares the body for emergency situations, often referred to as the 'fight or flight' response. It increases heart rate, dilates pupils, and redirects blood flow to muscles.
The parasympathetic nervous system restores normal body functions and conserves energy, known as the 'rest and digest' response. It decreases heart rate, constricts pupils, and promotes digestion.
The sympathetic system originates from the thoracolumbar region of the spinal cord and primarily uses norepinephrine at effector organs. The parasympathetic system originates from the craniosacral region and uses acetylcholine at effector organs.
Therefore, the statement that the sympathetic system prepares the body for emergency while the parasympathetic system restores normal function is correct.
Answer: sympathetic system prepares the body for emergency while parasympathetic system restores normal function.
