![CERVICALIS ASCENDENS—CERVICO-FACIAL. lying under the horizontal ramus of the lower jaw, and extending along the course of the external jugular vein underneath the platysma myoides ; they are most numerous above the clavicle, where the external jugular joins the subclavian vein. C. nerve, superficial. (F. nerf cervical transverse; Gr. oberjlachlicher Halsnerv.) A branch of the cervical plexus proceeding from the arch of the second and third cervical nerves ; it turns round the posterior border of the sterno- mastoid at its middle, perforates the cervical fascia, and divides beneath the platysma myoides into ascending and descending branches. C. nerve, trans'verse. Same as C. nerve, superficial. Cm nerves. (F. nerfs cervicaux ; Gr. Nack- ennerven.) The first eight pairs of spinal nerves. The common trunk, formed by the union of the two roots, is separated into two divisions, anterior and posterior. The first cervical is the subocci- pital nerve; the posterior division of the remain- ing nerves divides into external branches, which supply the splenius, cervicalis ascendens, trans- versalis colli, trachelo-mastoid and complexus muscles; and iw^erw^/branches, that of tlie second is the great occipital nerve; those of the third, fourth, and fifth nerves run beneath the com- plexus, forfning the posterior cervical plexus, to the vertebral spines, and then running outwards supply the integument over the trapezius; those of the sixth, seventh and eighth supply muscles only. The anterior divisions of the four upper cervi- cal nerves form the cervical plexus, those of the four lower cervical nerves form, together with that of the first dorsal, the brachial plexus. C. plex'us. (L. plexus, a plaiting. F. plexus cervical; G. Nackengeflecht, Halsgejlecht.) A nervous network formed by the interlacement of the anterior divisions of the first four cervical nerves. It lies opposite thefirstfour cervical verte- brae on the scalenus medius and the levator anguli scapulae muscles, and underneath the sternomas- toid. The branches are superficial and deep. The former are the superficialis colli, the auricularis magnus, the occipitalis minor, and the supra- clavicular ; these supply the integument- The deep branches are communicating twigs with the pneumogastric, hypoglossal, and sympathetic nerves, a branch to the rectus anterior and rectus lateralis muscles, one to the stenao-mastoid, one to the trapezius, the phrenic nerve, a branch to the angularis scapulae, and one to the rhomboidei muscles; the two latter sometimes proceed from the brachial plexus. C. plex'us, poste'rior. The intercommu- nication of the internal branches of the posterior divisions of the third, fourth, and cervical nerves beneath the complexus muscle. C. tri'an§:les. See Triangles of neck. C. vein, deep. (G. tiefe Nackenblutader.) The branches of this vein accompany those of the artery of the same name, and open into the ver- tebral vein. C. veins, ascending:. The branches ac- company those of the corresponding artery, and form a trunk which opens into the vertebral vein. C. ver'tebrse. (L. vertebra, a spine bone. . vertebres cervicales ; G. Ealswirbel, Nacken- wirbel.) The first seven vertebrae of the spine, the two upper of which are exceptional, the atlas and axis. The body is small, widest from side to side, the upper surfaces concave in the same di- rection, the lower concave from before to behind. The laminae are long and flat, the upper notches the deeper. The neural canal is triangular and large. The spinous process is short and bifid, but that of the seventh is long. The transverse pro- cesses are short and bifid, they spring by two roots, the anterior corresponding to a rib or its articulating capitular process, the posterior to a transverse process; they unite at their extremi- ties and form the vertebral canal. The articular processes are large and flat. The last cervical vertebra is the Vertebra prominens. C. zone. (L. zo7ia, a girdle.) A iexm ap- plied by Barnes to the part of the inner sui'face of the pregnant uterus which lies beneath an imaginary latitudinal circle drawn round the uterus at about a fourth of its height; it is the zone of dangerous placental attachment. Cervicalis ascendens. (L. cervix, the neck ; ascendo, to mount up. F. faisceaux cle renforcement de la partie superieure du sa- cro-lombaire; G. aufsteigender Nackenmuskel.) One of the outer columns of the erector spinae muscle, being a continuation upwards of the musculus accessorius. It arises by slips from the angles of four or five upper ribs, and is inserted into the posterior tubercles of the transverse pro- cesses of the fourth, fifth, and sixth cervical ver- tebrae. C. descen'dens. (L. descendo, to go down.) A synonym of C. ascendens, on the sup- position that the upper attachment of the muscle is its origin. Also, a synonym of the Descendens noni nerve. Cervica'ria. (L. cervix, the neck.) The Campanula trachelium, great throat-wort; be- cause believed to be efficacious in diseases of the throat and neck. Cervici'tiS. (L. cervix.) Inflammation of the cervix uteri. Cervicoacromia'lis. (L. cervix; acromion.) The anterior part of the ti-apezius muscle, including its attachment to the acro- mion. Cervi'co-bra'chial. (L. cervix; bra- chium, the arm.) Belonging to the neck and arm. C.-bra'cliial enlarg^e'ment. Same as Cervical enlargement. C.-bra'chial neurarg-ia. i^tvpov, a nerve; aXyos, pain.) Neuralgia of the brachial plexus and of the posterior branches of the lower part of the cervical plexus, manifesting itself in severe pains in the scapular and axillary regions, which shoot down the arms, hands, and back of the neck; there is often acute cutaneous hyper- a3sthesia also; the nerves most affected are branches usually of the ulnar, radial, or musculo- cutaneous nerves. It may be caused by cold, pressure, or a tumour, or wound. C tri'ang-le. See Triangle, cervico- brachial. Cervicodyn'ia. (L. cervix; oBvvt], pain.) Pain in the neck; stiff neck; muscular 1 heumatism of the neck. CerviCO-branch'ial. (L. cervix; bran- chice, the gills.) Belonging to the branchiae and the neck. C. fis'tula. (G. Halskiemenfistel.) Same as Branchial fistula. Cervi'co-fa'cial. (L. cervix; fades, the face.) Belonging to the neck and face. C. nerve. The lower of the two branches of the facial nerve, into which it divides, be- hind the ramus of the lower jaw; it subdivides](https://iiif.wellcomecollection.org/image/b21292917_0001_0806.jp2/full/800%2C/0/default.jpg)
