O knihe
Excerpt from The Development of the Oculomotor Nerve, the Ciliary Ganglion, and the Abducent Nerve in the Chick
Schwalbe, in his extensive and much-quoted work on Das Ganglion oculomotorii, shows that the ciliary ganglion is represented in the lower vertebrates by groups of ganglion cells distributed along the course of the oculomotor nerve. Passing upward toward the higher forms, the cells become more closely associated into a compact body, this change being accompanied by a gradual withdrawal of the ganglion from the trunk of the oculomotor nerve through the formation of a radix bre vis. However, not all the higher vertebrates possess short roots, since in many mammals (sheep, calf, dog, rabbit) none exists, the ganglion being placed directly on the trunk of the oculomotor. Schwalbe denies the existence of a connection between the ciliary ganglion and the tri geminal nerve in several species, and believes the sympathetic root to be confined to mammals. He, therefore, asserts that the ciliary ganglion belongs primarily to the oculomotor, which he considers entitled to the rank of an independent segmental nerve.
