Cranial nerves that carry parasympathetic fibers :-

Mnemonic ( 1973 )

10 = vagus nerve
9 = glossopharyngeal nerve
7 = facial nerve
3 = Oculomotor nerve

Horner ‘s syndrome :-


This condition results from lesions that interrupt the ipsilateral sympathetic nervous supply to the head, eye, neck.

- internal carotid (sympathetic) plexus supply :-

1. Pupillary dilator muscle(dilate pupil)

2. Muller (tarsal) muscle (elevate eyelid)

3.sweat gland(sweating)

- Clinical features of Horner’s syndrome :-

1. Triad of Horner’s syndrome :-

A. Miosis (constricted pupil ) due to impaired innervation of pupillary dilator muscle by sympathetic plexus )

B. Ptosis (droop eyelid ) due to impaired innervation of muller muscle (superior tarsal muscle) by sympathetic trunk

C. Anhidrosis ( absence of sweating ) due to impaired innervation of sweat gland by sympathetic trunk

2.Other Features :-

A.apparent Enophthalmos:- Impaired function of the superior tarsal muscle (müller) also results in an elevated lower eyelid.
So upper eyelid is dropped and lower eyelid is elevated which result of apparent enophthalmos

B.Facial flushing (due to vasodilation)as the vasoconstrictive effect of the sympathetic nervous system is lost.

These features occur ipsilaterally at the same side of lesion .
