Question

"Inspiratory center sends nerve impulses to the diaphragm via the:

A.phrenic nerve
B.vagus nerve.
C.accessory nerve.
D.glossophyrangeal nerve."

Answer 1

The inspiratory center sends nerve impulses to the diaphragm via the phrenic nerve. The phrenic nerve is responsible for the muscle contractions that drive ventilation.

Step-by-step explanation:

The inspiratory center sends nerve impulses to the diaphragm via the phrenic nerve. The phrenic nerve is connected to the spinal cord at cervical levels 3 to 5 and is responsible for the muscle contractions that drive ventilation. It is important for breathing as it stimulates the diaphragm to contract, causing inspiration.
