Semi-diagraiiiniatic View of a Peep Dissection of the Cranial Nerves on the Left Side of the Head
(Qiiain). The Roman numerals from I to XII indicate tlie roots of the several cranial nerves as
they lie in or near their foramina of exit. V is upon the large root of the tifth, with the Gas-
serian ganglion in front; CI, the suhoccipital or first cervical nerve; CVIII, the eighth. The
branches of the nerves are— 1, supraorbital branch of the fifth; 2, lachrymal passing into the
gland ; 3, nasal, passing toward the anterior internal orbital canal, and giving the long root to the
ciliary ganglion, 4'; ;i', termination of the nasal nerve: 4, lower branch of the third nerve; f>,
superior maxillary division of the tifth passing into the infraorbital canal; 5', the .same issuing
at the infraorbital foramen, and being distributed as inferior palpebral, lateral nasal, and supe-
rior labial nerves; .">", fi, ganglion of >Ieckel and Vidian nerve passing back from it; 6', palatine
and other nerves descending from it ; 6", large superficial petrosal nerve ; 7, posterior dental
nerves ; "', placed in the antrum, which has been o))ened, points to the anterior dental nerve ; S,
inferior ma.xillary division of the fifth; 8', muscular branches coming from it; Sx, the auriculo-
temporal branch cut short, and above it the small superficial petro.sal nerve connected with the
facial ; 9, buccal and external pterygoid ; 10. lingual or gustatory 10', its distribution to the side
;
and front of the tongue and sublingual .gland ; 10". submaxillary ganglion ; below 10, the chorda
tynipani passing forward from the facial to Join the lingual; 11. inferior dental nerve; 11', the
same and part of its dental distribution exposed ; U", its termination a.s the mental nerve; 11'",
its mylo-hyoid branch; 12, twigs of the facial nerve immediately after its fxit from the stylo-
mastoid foramen, distributed to the posterior belly of the diitastric and stylo-hyoid muscles; 12',
teniporo-facial division of the facial ; 12", cervico-facial division ; 13. trunk of the glosso-pharyn-
geal ; VV, its distribution on the side and back part of the tongue ; 14, spinal accessory nerve ; 14',
the same after having passed through the sterno-mastoid muscle, uniting with branches from the
cervical nerves; l.'i, hypoglossal nerve; l-i', its twig to the thyro-hyoid muscle; l.i", its distribu-
tion to the muscles of the tongue; Ifi, its descending branch, giving'a branch to the anterior belly
of the omo-hyoid muscle, and receiving communicating branches at 16x from the cervical nerves
17, pneumogastric nerve; 17', its superior laryngeal branch; 17", external laryngeal twig; IS,
superior cervical ganglion of the sympathetic nerve, uniting with the upper cervical nerves, and
giving at is' the superficial cardiac nerve ; 19, the trunk of the sympathetic; 19', the middle cer-
vical ganglion, uniting with some of the cervical nerves, and giving at 19" the large or middle
cardiac nerve: 20, continuation of the sympathetic nerve down the neck; 21, great occipital
nerve; 22, third occipital.
