DEEP PETROSAL nerve arises from
High-Yield Explanation
The deep petrosal nerve, sympathetic in nature is a branch of the sympathetic plexus around the internal carotid aery. It contains postganglionic fibres from the superior cervical sympathetic ganglion. The nerve joins the greater petrosal nerve to form the nerve of the pterygoid canal. The sympathetic fibres in it are distributed through the branches of the pterygopalatine ganglion. Ref: BD Chaurasia's HUMAN ANATOMY, Volume 3, 4th edition.
