Abstract

THE NONCHROMAFFIN paraganglionic (N. C. P.) system composing such structures as the carotid body, the glomus jugulare, and others to be mentioned below is probably a system of organs consisting of masses of nonchromaffin tissue, closely related to the parasympathetic division of the autonomic nervous system and its ganglia. This N. C. P. system should not be confused with other systems, such as the chromaffin system, which includes the adrenal medulla and rests of chromaffin cells associated with visceral sympathetic ganglia, especially along the thoracolumbar chain and the celiac and pelvic plexuses. Other systems to be differentiated include the carotid and aortic sinuses, which are pressoreceptors, and the neuromyoarterial glomus, which gives rise to the glomus tumors of the fingers and toes.

The N. C. P. system includes such structures as the following:

  1. The glomus caroticum, or carotid body

  2. The glomus jugulare and paraganglia tympanicum

  3. The aortic-arch
