What happens in the respiratory center during forced expiration?
A) The inspiratory neurons of the dorsal respiratory group send action potentials for scalene muscle relaxation.
B) The pre-Bötzinger complex sends action potentials for sternocleidomastoid muscle contraction.
C) Neurons in the pontine respiratory center send action potentials to the diaphragm.
D) The inspiratory neurons of the dorsal respiratory group get activated.
E) The expiratory neurons of the ventral respiratory group get activated.
