Innervation of Tracheobronchial Tree: Schema Anatomy
From hypothalamic and higher
centers, Glossopharyngeal
nerve (CN IX), Descending
tracts in spinal cord, Thoracic spinal cord, Vagus
nerve (CN X) (cholinergic; efferent
to smooth muscle and glands; afferent from aorta tracheobronchial mucosa, and alveoli), Afferent nerves from nose and sinuses (via trigeminal [CN V] and glossopharyngeal [CN IX] nerves) may also initiate reflexes in airways Superior cervical ganglion, Sympathetic nerves (adrenergic),
Carotid sinus, Carotid body, Common carotid artery, Superior laryngeal nerve, Larynx, Arch of aorta, Left recurrent laryngeal nerve, Cough receptors, Cough receptors, Irritant receptors, Pulmonary plexus, Sympathetic trunk, Stretch receptors (Hering-Breuer reflex), Parasympathetic fibers, Sympathetic fibers, Afferent fibers, T1, T2, T3, T4, T5, Inferior ganglia.
