Function of intermediate zone within grey matter → Contains cell bodies of preganglionic sympathetic neurons
Function of lateral horn within grey matter → Contains cell bodies of preganglionic sympathetic neurons
Function of Ventral Horn within grey matter → Motor neurons send axons through ventral root to innervate mm. fibers
