Luschka's joints. 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 ...
The meningeal branches of the spinal nerves (also known as recurrent meningeal nerves, sinuvertebral nerves, or recurrent nerves of Luschka) are a number of small nerves that branch from the segmental spinal nerve near the origin of the anterior and posterior rami, but before the rami communicans; rami communicantes are branches which communicate between the spinal nerves and the sympathetic ...
Coccygeal glomus. Section of an irregular nodule of the glomus coccygeum. X 85. The section shows the fibrous covering of the nodule, the bloodvessels within it, and the epithelial cells of which it is constituted. The coccygeal glomus (coccygeal gland or body; Luschka ’s gland) is a vestigial structure [ 1 ] placed in front of, or ...
Facet syndrome. Facet syndrome is a syndrome in which the facet joints (synovial diarthroses) cause painful symptoms. [1] In conjunction with degenerative disc disease, a distinct but functionally related condition, facet arthropathy is believed to be one of the most common causes of lower back pain. [2][3]
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.
The median aperture (median aperture of fourth ventricle or foramen of Magendie) is an opening at the caudal portion of the roof of the fourth ventricle. [1] It allows the flow of cerebrospinal fluid (CSF) from the fourth ventricle into the cisterna magna. [2][3] The other openings of the fourth ventricle are the lateral apertures - one on ...
Diffuse idiopathic skeletal hyperostosis (DISH) is a condition characterized by abnormal calcification/bone formation (hyperostosis) of the soft tissues surrounding the joints of the spine, and also of the peripheral or appendicular skeleton. [ 1 ] In the spine, there is bone formation along the anterior longitudinal ligament and sometimes the ...
Drawing of a cast of the ventricular cavities, viewed from the side. The cerebral aqueduct (aqueduct of the midbrain, aqueduct of Sylvius, Sylvian aqueduct, mesencephalic duct) is a small, narrow tube connecting the third and fourth ventricles of the brain. [1][2] The cerebral aqueduct is a midline structure that passes through the midbrain.
