The angle formed by the two ventral flexures, the cephalic flexure and the cervical flexure together, is a right angle in the ventral direction between the axis of the body and the axis of the brain. The pontine flexure is located between these two flexures. Isthmic organizer at the midbrain-hindbrain boundary.
Cervicocranial syndrome or (craniocervical junction syndrome, CCJ syndrome) is a combination of symptoms that are caused by an abnormality in the cervical vertebrae leading to improper function of cervical spinal nerves. Cervicocranial syndrome is either congenital [1] or acquired. [2]
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
The constellation of symptoms caused by craniocervical instability is known as "cervico-medullary syndrome" [4] and includes: [5] [6] [7] Anxiety disorder; Bobble-head doll syndrome, a sensation that the skull may fall off the cervical spine; Clumsiness and motor delay; Cognitive and memory decline; Double or blurred vision; Dysphagia, or the ...

Cephalic disorders (from Greek κεφαλή 'head') are congenital conditions that stem from damage to, or abnormal development of, the budding nervous system.. Cephalic disorders are not necessarily caused by a single factor, but may be influenced by hereditary or genetic conditions, nutritional deficiencies, or by environmental exposures during pregnancy, such as medication taken by the ...
Cervical canal stenosis may lead to myelopathy, a serious condition causing symptoms including major body weakness and paralysis. [14] Such severe spinal stenosis symptoms are virtually absent in lumbar stenosis , however, as the spinal cord terminates at the top end of the adult lumbar spine, with only nerve roots ( cauda equina ) continuing ...
Barré–Liéou syndrome is regarded by many current medical researchers as synonymous with cervicogenic headache. Thus, the original works of Barré and Liéou were foundational in identifying a crucial feature that distinguishes cervicogenic headache from other headache syndromes—the concept that the pain originates from a structural ...
