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]
Craniocervical instability is more common in people with a connective tissue disease, including Ehlers-Danlos syndromes, [1] osteogenesis imperfecta, and rheumatoid arthritis. [2] It is frequently co-morbid with atlanto-axial joint instability, Chiari malformation , [ 3 ] or tethered spinal cord syndrome .
Patients who exhibit extreme joint hypermobility and connective tissue weakness as a result of Ehlers–Danlos syndrome or Marfan syndrome are susceptible to instabilities of the craniocervical junction; thus they are at risk for acquiring a Chiari malformation. Headache, neck pain, unsteady gait usually during childhood [4] 1.5
Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
Craniocervical junction misalignment is also suspected as a factor in neurodegenerative diseases where altered CSF flow plays a part in the pathological process. Hyperextension (Whiplash) Injury A rear-end traffic collision or a poorly performed rugby tackle can both result in the head being whipped back on the shoulders, causing whiplash.
Thermoreceptors of the skin sense the temperature of water. A thermoreceptor is a non-specialised sense receptor, or more accurately the receptive portion of a sensory neuron, that codes absolute and relative changes in temperature, primarily within the innocuous range.
One study found that male German Shepherd Dogs with a lumbosacral transitional vertebra are at greater risk for cauda equina syndrome, which can cause rear limb weakness and incontinence. [ 10 ] The significance of transitional vertebrae has been questioned by one study finding similar prevalence in the general population as those with low back ...
Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.
