Cervicothoracic ganglion

From Biology-Online Dictionary | Biology-Online Dictionary
Jump to: navigation, search



A ganglion in the cervicothoracic region of the sympathetic trunk, formed by the fusion of the inferior cervical ganglion and the first thoracic ganglion.


This ganglion is specifically located anterior to the transverse process of the seventh cervical vertebrae, posterior to the neck of the first rib, below the subclavian artery, and close to the first thoracic ganglion, with which it is usually fused.

Blocking this ganglion is found to reduce the severity and frequency of hot flashes, especially in breast cancer survivors.
