Respiratory center

The center which controls respiratory functions is in the medulla and pons. There are three locations

Dorsal respiratory group; This is placed at the dorsal aspect of the medulla and it causes iinspiration.

Ventral respiratory group: This is placed at the ventrolateral part of the medulla within its reticular formation. It is responsible for expiration.

Pneumotaxic center: This is placed at the superior aspect of the pons and it controls depth and rate of breathing.

The above centers discharge via the vagus and glossopharyngeal neurons to the periphery such as the intercostal muscles, lungs,   diaphragm, which are the peripheral apparatus that perform respiration.
