The respiratory center rhythmically sends neural output to the diaphragm and ____________ muscles to regulate quiet breathing. T
he respiratory center is stimulated to alter breathing rate and depth by ____________ input from ____________ in the brain. Additional input comes from peripheral receptors, including ____________ within the carotid and aortic bodies, ____________ of the mucosal lining of the respiratory tract, ____________ of the lungs and visceral pleura, and ____________ of the joints. Breathing can be consciously controlled by the ____________ , which bypasses the respiratory center to directly stimulate lower motor neurons.
The respiratory center rhythmically sends neural output to the diaphragm and <u>external intercostal muscles</u> to regulate quiet breathing. The respiratory center is stimulated to alter breathing rate and depth by <u>sensory input</u> from central chemoreceptors in the brain. Additional input comes from peripheral receptors, including <u>chemoreceptors</u> within the carotid and aortic bodies, <u>irritant receptors</u> of the mucosal lining of the respiratory tract, <u>stretch receptors</u> of the lungs and visceral pleura, and <u>proprioceptors</u> of the joints. Breathing can be consciously controlled by the <u>cerebral cortex</u>, which bypasses the respiratory center to directly stimulate lower motor neurons.
Biome, though some might say ecosystem instead. Biomes are very large ecosystems that cover broad areas.<span>If they specify "one" reef, then they are probably looking for "ecosystem"</span>
