THE SPINAL NERVES. 183 



(b) Muscular twigs to the Longissimu* darn, Intertransver&arii 

 capiti*, Levator anguli scapulae, and the Retrahens scapulae. 



(c) When near the glossopharyngeal it supplies twigs to the 

 Geniohyoideus, Sternofiyoideus, and OmoTtyoidem, where it bifurcates. 



(d) One of the branches passes inwards to supply the Hyoglossu*. 



(e) The other terminal branch passes forwards with the Ramvs 

 lingual is and the glossopharyngeal, between the fibres of the Genio- 

 hyoideus, which it partially supplies, and sends twigs to the neigh- 

 bouring parts. 



(f) [Hoffmann describes a communicating branch to the pneu- 

 mogastric nerve, which the translator has not been able to discover, 

 and which no other observer has mentioned.] 



2. The second spinal or brachial nerve (X. brachialis, N. spinalis 

 II), (Fig. 122) is a large nerve, leaving the vertebral canal between 

 the second and third vertebrae ; it then accompanies the Art. afil- 

 laris along the anterior border of the transverse process of the third 

 vertebra, over the hinder end of the Muse, lerator scapulae and the 

 anterior end of the m. transverso-scapularis major, to the inner border 

 of the Muse. subscapularis, under which it passes into the arm. In 

 this course it gives off or receives the following branches : 



(a) It first receives a branch from the second spinal nerve. 



(b) It gives off a large branch, the N. coraco-clavicularis (Fig. 1 22 

 Cc), which first accompanies a branch of the Art. axillaris on the 

 Muse, letat. scapulae, then courses forwards and outwards over the 

 31 use. infacapularu to pass from above into the Foramen ovale be- 

 tween the clavicle and coracoid bones. It gives off two branches : 



(1) One immediately beyond its origin, which runs backwards 

 over the Muse, subscapularis to supply the Muse, olliq. abdominis in- 

 ternus (Fig. 1 22 Cc). 



(2) While in the Foramen ovale, the N. coraco-claticularis bifur- 

 cates ; the anterior twig runs forwards and outwards to the deltoideu* 

 and also supplies a recurrent filament to the Muse, sterno- radial is ; 

 the posterior twig enters the upper surface of the' Muse, sterno- 

 radiali*. 



(c) At the outer extremity of the Muse, transterso-scapulari* the 

 brachial nerve gives off a posterior branch, which at once bifurcates : 



(1) The first branch passes into the under surface of the Muse, 

 latissimus dorsi (Id), giving a twig to the Infraspinafw. 



(2) The second is the Ramus cutanem axillari* (lie) ; it passes on
