Arcuate Foramen: An Anatomical Variation in the Atlas Vertebrae

International Journal of Anatomy and Research, 2022
Background: Arcuate foramen is a variation in the posterior arch of atlas vertebrae. It is commonly called as Kimmerle’s anomaly, also known as Ponticulus Posticus. It is the product of the complete or incomplete ossification of the posterior atlantooccipital membrane over the vertebral artery groove resulting in the formation of arcuate foramen ...

An anatomical study of the morphometric differences between complete arcuate foramina and ipsilateral foramina transversaria in human atlas vertebrae: Could these be responsible for vaso-occlusive symptoms?

National Journal of Clinical Anatomy, 2019
Background and Aims Arcuate foramina (AF), the atlas bridges formed by a delicate bony spicule over the posterior arch of atlas, have been implicated in the compression of the vertebral artery during extreme rotation of head and neck movements. Reduction

The petrosal artery and its variations: a comprehensive review and anatomical study with application to skull base surgery and neurointerventional procedures

Folia Morphologica, 2023
BACKGROUND: The petrosal artery supplies several structures at the skull base and is often the focus of various neurointerventional procedures. Therefore, knowledge of its anatomy and variations is important to surgeons and interventionalists.

ARCUATE FORAMEN OF ATLAS VERTEBRA [PDF]

, 2016
The Arcuate foramen is a bony arch which connects the posterior end of the superior articular fossa with the posterior arch of atlas. In case of presence of arcuate foramen the vertebral artery follows the normal course but it has to traverse through the

Minimally invasive surgical treatment for Kimmerle anomaly

Journal of Craniovertebral Junction and Spine, 2017
Introduction: Kimmerle anomaly is the bony ridge between the lateral mass of atlas and its posterior arch or transverse process. This bony tunnel may include the V3 segment of the vertebral artery, vertebral vein, posterior branch of the C1 spinal nerve,

Assessments of Prevalence of Ponticulus Posticus, Atlas Posterior Arch Deficiency, Sella Turcica Bridging, Maxillary Canine Impaction, and Associations Among Them in 500 CBCTs of Italian Orthodontic Patients

Frontiers in Dental Medicine, 2021
Background: The ponticulus posticus (PP) is an important anomaly of the atlas (C1 vertebra) with a complete or partial bone bridge that transforms the groove of the vertebral artery (VA) into a canal (arcuate foramen).

Melanocortins and agouti-related protein modulate the excitability of two arcuate nucleus neuron populations by alteration of resting potassium conductances [PDF]

, 2007
The hypothalamic melanocortin system is crucial for the control of appetite and body weight. Two of the five melanocortin receptors, MC3R and MC4R are involved in hypothalamic control of energy homeostasis, with the MC4R having the major influence. It is

Associations across 22 dental and craniovertebral anomalies or variations, sagittal skeletal relationships, and vertical growth patterns: a comprehensive epidemiological study of 43 dentoskeletal traits

BMC Oral Health, 2023
Introduction Despite researchers' recent interest in identifying links between some dental and craniovertebral abnormalities, there are many important, unassessed gaps in our knowledge of this matter. In addition, previous samples were small.

Two simultaneous anatomical variations of the cervical spine — a case report discussing the concept of tandem anomalies

Folia Morphologica
BACKGROUND: Arcuate foramen is an ossification of the posterior atlanto-occipital membrane, forming a bony opening through which the vertebral artery (VA) enters the vertebral canal.
