Autonomic Innervation of the Orbit, Dr Adel Bondok

Dr Adel Bondok Anatomy Channel.
The video describes the autonomic innervation of the orbit.
@ What are the structures supplied by autonomic nerves in the orbit?
1. 4 muscles: 2 by sympathetic fibers (Muller’s muscle and dilator pupillae) and 2 by parasympathetic fibers (sphincter pupillae and ciliary muscle).
2. Lacrimal gland: parasympathetic (facial nerve) and sympathetic (deep petrosal nerve).
3. Blood vessels.
@ How the sympathetic fibers reach the muscles?
@ How the parasympathetic fibers reach the muscles?
@ Ciliary ganglion: location, roots and branches.
@ What is the pathway (routes) of the parasympathetic and sympathetic fibers to the lacrimal gland?
@ What are the parasympathetic ganglia associated with the parasympathetic innervation?
1. Ciliary ganglion: oculomotor nerve
2. Sphenopalatine (pterygopalatine) ganglion: facial nerve.
@ What is the effect of a lesion in the sympathetic fibers?
@ What is the effect of a lesion in the parasympathetic fibers?
