The ventricular system in the brain consists of four cavities that are interconnected and function together to ensure that many of the biological needs of the body's systems are met. The four cavities that exist in the human brain are what are referred to as the ventricles, and the ventricles represent a range of different sizes. These structures develop early in the embryological development in humans and are an offshoot of the neural canal in the early stages of an embryo's growth. These ventricles perform a vital function for the body through the production of the cerebrospinal fluid (CSF) by the choroid plexuses that are located within them. This paper will briefly give an illustrated introduction to the development, structure, and functioning of this vital bodily function.
Development and Structure
The brain ventricular system is composed of a highly conserved set of cavities that contain cerebrospinal fluid (CSF), a protein-rich fluid essential for brain function, yet, little is known about the function of embryonic CSF (eCSF), or the mechanisms of CSF production, retention, and circulation that regulate brain ventricle shape and size (Chang, 2012). Researchers however are...
Soluble triggering receptor expressed on myeloid cells 1 (sTREM-1) were found to be a biomarker in cerebrospinal fluid during the presence of bacterial meningitis; however, it is not yet recommended for clinical practice (Brouwer et al., 2010). Blood cultures and skin biopsy have been used to detect causative pathogens in patients when cerebrospinal fluid cultures are negative or unavailable, but these tests are not definitive enough to be used
, 1998). Cognitive functioning, particularly memory performance has been found to be impaired in patients with childhood onset of growth hormone deficiency and HGH replacement therapies have been found to offset this memory impairment (Arwert et al., 2005). Studies have identified a link between improved attention and increases in memory performance in children with growth hormone deficiency (Arwert et al., 2005; Arwert et al., 2006). This is due to the
Research Methods At the current time, no clinical studies have been conducted that use a randomized sample and strict controls in relation to the use of statins to prevent and control Alzheimer's Disease. The proposed research intends to fill this important research gap and conduct a clinical study that compares the development of Alzheimer's Disease between patients that use statins and a group that does not use statins for a specified
Fibromyalgia syndrome (FMS) is a complex medical condition that affects about 5 million American people. The condition is characterized by "chronic widespread pain, fatigue, sleep disturbance, stiffness, impaired memory and concentration, anxiety and depression." (Facts of Life, 2001). Sleep disturbance and an increased sensitivity to pain follow a cyclic pattern in individuals having FMS, the result of which is a positive feedback loop. (Etiology of Fibromyalgia, 2003). Typically, fibromyalgia affects women,
Nerves Damaged Spinal Tap Nerves Damaged During Spinal Tap: Can a spinal tap cause a person pain, numbness and weakness in the right lower leg for life? The complications resulting from lumbar puncture (spinal tap) have been well documented in the neurosurgical literature. These complications include mild backache, persistent headache, meningitis, and herniated disc, as well as inoculation of epidermal tissue, and the associated growth of epidermoid tumors (Siddiqi and Buchheit, 1982). There
