The correct answer is: A) pontine respiratory centers
The respiratory centre in the pons is responsible for generating and maintaining the rhythm of respiration. Besides this elementary function, it also has the ability to adjust respiration rhythm in c response to physiological changes. Respiratory centre consists of three major respiratory groups of neurons:
• The dorsal respiratory group (DRG)- initiates inspiration (inhalation)
• the ventral respiratory group (VRG)-responsible for exhalation
• Pontine respiratory group- includes the pneumotaxic (controls both the rate and the pattern of breathing) and apneustic centers (promotes inhalation by sending signals to dorsal group).

I think the answer is <span>epithelial and connective tissue
Muscle cells need much energy to moves its fiber, so it must be on a highly vascularized area. The nervous system also needs a blood supply to works. In fact, the brain cells use the highest amount of energy.
Epithelial and connective tissue doesn't need much energy because its main function is to protect other tissue. It also has densely packed cells to make it sturdy.</span>
