Middle cervical ganglion
Middle Cervical Ganglion
The Middle Cervical Ganglion (pronunciation: /ˈmɪdəl ˈsɜːrvɪkəl ˈɡæŋgliən/) is a part of the sympathetic nervous system that is located near the neck region of the human body.
Etymology
The term 'Middle Cervical Ganglion' is derived from the Latin words 'medius' meaning middle, 'cervix' meaning neck, and 'ganglion' meaning a mass of nerve tissue.
Anatomy
The Middle Cervical Ganglion is typically the smallest of the three cervical ganglia. It is located on the vertebral artery, near the sixth cervical vertebra. It sends grey rami communicantes to the fifth and sixth cervical spinal nerves and gives off branches that form the thyrocervical trunk.
Function
The Middle Cervical Ganglion primarily serves to distribute the sympathetic nerve supply to the structures in the neck. It plays a crucial role in the regulation of heart rate, blood pressure, and other vital functions.
