Anatomy of the frst spinal nerve: a review

In this simple review we discuss some important anatomical and functional aspects of the first cervical nerve (C1). The C1 has considerable clinical importance, and the particulars of this nerve are conflicting among several authors, thus, the present review shall be essential for health sciences and those who keep some interest in pathologies associated with the nerves of the neck. For the preparation of this text were consulted papers published in English and textbooks. The articles were accessed from a basic search on SciELO, MEDLINE, PubMed, LILACS, Google Scholar and ScienceDirect.

Atlanto-occipital fusion and its neurological complications: a case report

During routine activities in the Laboratory of Human Anatomy at the University of Santa Cruz do Sul – Brazil, an atlanto-occipital fusion was observed in a Caucasian cadaver skull. The skull used in our study had complete fusion of the occipital bone with the atlas vertebra, except in traffic areas of the vertebral arteries. Some important neurological disorders seem to be related with atlanto-occipital fusion. The presence of other anatomical variations was not verified. Thus, the present study shall be important for health sciences and those who keep some interest in pathologies associated with brain.
