In anatomy, Luschka's joints (also called uncovertebral joints, neurocentral joints) [1] are formed between uncinate process or "uncus" below and uncovertebral articulation above. [2] They are located in the cervical region of the vertebral column from C3 to C7. [3] Two lips project upward from the superior surface of the vertebral body below ...
A thoracic vertebra. (Superior labeled at top; inferior labeled at bottom.) The articular process or zygapophysis (Greek: ζυγόν, romanized: zugón, lit. ' yoke ' + apophysis) of a vertebra is a projection of the vertebra that serves the purpose of fitting with an adjacent vertebra. The actual region of contact is called the articular facet.
In tetrapods, cervical vertebrae (sg.: vertebra) are the vertebrae of the neck, immediately below the skull. Truncal vertebrae (divided into thoracic and lumbar vertebrae in mammals) lie caudal (toward the tail) of cervical vertebrae. [ 1 ] In sauropsid species, the cervical vertebrae bear cervical ribs. In lizards and saurischian dinosaurs ...
The anterior tubercle on the sixth cervical vertebra is called the carotid tubercle because it separates the carotid artery from the vertebral artery. There is a hook-shaped uncinate process on the side edges of the top surface of the bodies of the third to the seventh cervical vertebrae and of the first thoracic vertebra. Together with the ...
The inferior processes or postzygapophysis project downward from a higher vertebra, and their articular surfaces are directed more or less forward and outward. The articular surfaces are coated with hyaline cartilage. In the cervical vertebral column, the articular processes collectively form the articular pillars. These are the bony surfaces ...
All cervical vertebrae have transverse processes attached except the first one. This vertebra (C1) is called the atlas which articulates with the occipital condyles of the skull and lacks the foramen typical of most vertebrae. [7] The neck of a bird is composed of many cervical vertebrae enabling birds to
The facet joint is the joint between the inferior articular process (labeled at bottom) and the superior articular process (labeled at top) of the subsequent vertebra. The facet joints (also zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae.
Neurosurgery. Clay-shoveler's fracture is a stable fracture through the spinous process of a vertebra occurring at any of the lower cervical or upper thoracic vertebrae, classically at C6 or C7. [1] In Australia in the 1930s, men digging deep ditches tossed clay 10 to 15 feet above their heads using long handled shovels. [2]
