Introduction: Foramen transversarium are the characteristic bony feature of the cervical vertebrae. They are located on the transverse process of cervical vertebrae through which second part of vertebral artery passes along with vertebral venous and sympathetic plexus. Their variations are common with regard to size, shape, incomplete, duplicated and may even absent. Material & Methods: Two hundred foramen transversarium of one hundred atlas vertebrae were examined for morphological variations. Results: Out of hundred atlas vertebrae examined, foramen transversarium was present in all. Absence of costal element was noticed in four atlas vertebrae. Four atlas vertebrae showed incomplete bilateral foramen transversarium while four showed unilateral duplicated foramen transversarium. Conclusion: The increasing incidence of neck injuries and related syndromes necessitates the study of bony variations of the atlas vertebra and its foramen transversarium. The second part of vertebral artery is prone to be damaged during neck surgeries and posterior cervical injuries due to incomplete formation of the foramen transversarium, hence the knowledge of such variations is important for surgeons, otorhinolaryngologists, neurologists, orthopedicians, radiologists and physicians.

Background: In cervical vertebrae, the costal and transverse elements are connected to each other around the foramen transversarium of the transverse process. The adult cervical vertebrae are characterized by the presence of Foramen Transversarium (FT) in transverse process. These transverse foramina are found to have variations in size, shape and numbers and may be absent, incomplete or duplicate, which may lead to various symptoms. Aim: To study the anatomical variations of cervical vertebrae. Materials and methods: The present observational study was performed on 182 dry human cervical vertebrae of unknown sex and age. Intact cervical vertebrae without any degenerative or traumatic disorders were included in this study. Deformed and damaged vertebrae were excluded from the study Results: Out of these 364 foramen transversarium, 98 (27%) foramen transversarium were of type-I. Type -I was the most common presentation in the present study. Type -II foramen transversarium were seen in 33 (09%) foramen transversarium. Out of 364 foramen transversarium 88 (24%) foramen transversarium were of type-III. Type-IV foramen transversarium were seen in 62 (17%) foramen transversarium. Type-V foramen transversarium were seen on 83 (23%) foramen transversarium. Out of 182 vertebrae 40 (22%) showed complete double foramen transversarium. Incomplete double foramen transversarium were seen in 24 (13%) of vertebrae. One side complete & other side incomplete foramen transversarium were seen in 04 (02%) vertebrae. Conclusion: Knowledge of such variations is important for Physicians, Neurologists Otorhinolaryngologists, radiologists and Orthopedicians. Presence of accessory foramen transversarium especially of incomplete variety, the second part of vertebral artery may be dislodged and prone to get damaged easily during posterior cervical injuries. It helps in radiological imaging, neurological diagnosis and complex surgical procedures in the cervical area. KEY WORDS: Cervical Vertebrae, Foramen transversarium, Accessory Foramen Transversarium.

Morphological variation in the attachment sites of the ligamentum lamina nuchae and ligamentainterspinalia to the 2nd to 7th cervical vertebrae is described in four species of Equus, and enthesis patterns inrelation to these attachment sites are explored. This comparative study provides new insights with respect tothis variation in the zebrine and asinine clades within Equus. In zebrines (Equus caballus, E. quagga boehmiand E. przewalskii), the ligamentum lamina nuchae attaches to the eminence of the cervical dorsal spinesfrom either the 2nd to 5th, and or 2nd to 7th. These attachments resemble digits and between each digit anaperture is apparent. The ligamenta interspinalia attach to the base of each cervical dorsal spine from the 2ndto 7th before progressing caudally onto the thoracic dorsal spines. Three enthesis patterns per cervical dorsalspine correspond to the size and shape of these ligaments. In contrast, in asinines (as represented by Equusasinus), the ligamentum lamina nuchae attaches without digitation to the complete sagittal ridge of the cervicalvertebra including the dorsal spine and exhibits no ligamenta interspinalia. Consequently, the enthesispattern is represented by a raised sagittal ridge only, excluding the 7th cervical dorsal spine. These differencesbetween the ligamentum lamina nuchae and ligamenta interspinalia attachment sites create distinct enthesispatterns that differentiate zebrines from asinines. Findings include: differing ligamentous morphology; associatedenthesis patterns corresponding to attachment sites of the ligaments to the cervical vertebrae; influencesin dorsal spine morphology subject to the presence or absence of the ligaments; and the postulation ofevolutionary functional adaptions in response to environmental influences between the two Equus clades.These results may be useful for palaeontologists in the identification of isolated cervical vertebrae.

Lateral Profile

The lateral profile of the 6th and 7th cervical spinous processes (CSPs) were examined in four extantspecies of Equus (n=33); E. caballus (n=26), E. przewalskii (n=3), E. quagga boehmi (n=1), E. asinus (n=3)and compared to pre-domesticated Equus specimens (n=66) representing three known species: E. occidentalis(n=56), E. mosbachensis (n=2), E. curvedins/insulatis (n=1) and unknown Equus species (n=7) from five museums.Six common morphological profiles were revealed: cuneate, curvate, falcate, rudimentary, scalenate,and truncate. For the 6th CSP, the distribution of these morphologies amongst extant Equus is: cuneate, onlyE. asinus; curvate, E. caballus and E. przewalskii always in combination with ligamentum lamina nuchae (lig.lamina nuchae) attachments from the 2nd through to 7th CSP inclusive; falcate, E. caballus and E. przewalskiialways in combination with lig. lamina nuchae attachments from the 2nd through to 7th CSP inclusive;rudimentary, E. caballus always associated with lig. lamina nuchae attachments from the 2nd through to 5thCSP inclusive; scalenate, E. caballus in association with lig. lamina nuchae attachments from the 2nd throughto 5th (n=11) or 7th (n=4) CSP inclusive; truncate, not present. The 6th CSP in museum specimens of Equusexhibits one of four profiles: cuneate (n=10), curvate (n=14), scalenate (n=11) and truncate (n=4). For the 7thCSP, the distribution of these morphologies amongst extant Equus is: curvate, E. caballus mostly associatedwith lig. lamina nuchae attachments from the 2nd through to 5th CSP inclusive, falcate, E. caballus mostly associatedwith lig. lamina nuchae attachments from the 2nd through to 7th CSP inclusive, scalenate, E. caballusassociated with lig. lamina nuchae attachments from the 2nd through to 5th CSP inclusive. Only Rancho LaBrea and Tar Pits Museum provided samples suitable for examination of the 7th CSP. These exhibited fourprofiles: curvate (n=7), falcate (n=11), scalenate (n=2), and truncate (n=7). These findings suggest that thelateral profile of the 6th CSP is of potential use in identification of species; attachments of the lig. lamina nuchaealter the morphology of the 6th and 7th CSP; and that attachments of the lig. lamina nuchae on the 2ndto 7th CSP were likely present in species of Equus prior to domestication.

AbstractThe cervical vertebrae presents foramen transversaria in each transverse process. In all but the seventh cervical vertebra, the foramen normally transmits vertebral artery and vein and a branch from the cervicothoracic ganglion.140 cervical vertebrae were studied. Variations were noticed in the number of foramen transversarium unilaterally and bilaterally. Variations in foramen transversarium may indicate the variation in course of vertebral arteries
