2023年12月6日 · The atlas (plural: atlases) is the first cervical vertebra, commonly called C1. It is an atypical cervical vertebra with unique features. It articulates with the dens of the axis and the occiput, respectively allowing rotation of the head, and flexion, extension and lateral flexion of …

In anatomy, the atlas (C1) is the most superior (first) cervical vertebra of the spine and is located in the neck. The bone is named for Atlas of Greek mythology, just as Atlas bore the weight of the heavens, the first cervical vertebra supports the head. [1]

The C1 vertebra, known as the atlas, is the superior-most vertebra in the spinal column. It plays vital roles in the support of the skull, spinal cord, and vertebral arteries and provides attachment points for several muscles of the neck.

2023年10月30日 · The atlas is the first vertebra of the vertebral column, located in the most superior portion of the cervical region of the vertebral column. The atlas articulates superiorly with the occipital condyles found on each side of the foramen magnum of the skull.

The C1 vertebra, also called atlas, is shaped like a ring. The C2 vertebra has an upward-facing long bony process called the dens. The dens forms a joint with the C1 vertebra and facilitates its turning motions, thereby allowing the head to turn in different directions.

2023年10月24日 · The cervical spine comprises 7 vertebrae (C1 to C7) and is divided into 2 major segments. The 2 most cephalad vertebrae, the atlas (C1) and the axis (C2), form the craniocervical junction (CCJ) together with the occiput.

The Atlas (the first cervical vertebra - C1) differs from the other cervical vertebrae in that it has no body or spinous process. It is comprised of two bony arches with two bony masses laterally. It articulates with the Occiput above and C2 (the Axis ) below.

2025年3月7日 · The atlas (C1) vertebra represents a unique anatomical structure, distinctly different from all other vertebrae in the spinal column. As the first cervical vertebra, it supports the skull and enables precise head movements through its specialized architecture.

This 3D model shows the anatomy of vertebra C1 (also known as the atlas), with annotations. The skull sits atop this bone. This model is made with a model bone.
