Four so-called transits are considered basic clinical sites: the craniocervical, cervicothoracic, thoracolumbar and lumbosacral transit. From the clinical, functional and structural aspect it is however necessary to consider also the segment C4/5 and partly also C5/6 as a transit area. Therefore the author suggests to consider this segment also a specific transit area and recommends for it the term cervicocervical transit. Clinical and structural data are present which support this recommendation. Abbreviated version presented at the Vllth Congress of the Society of Manual Medicine, Jeseník 2001
