Spinal cord perfusion refers to the blood flow within the spinal cord, which is essential for delivering oxygen and nutrients while removing metabolic waste to maintain its function and health. Adequate perfusion is crucial to prevent ischemia and potential neurological damage, especially during surgical procedures or in the context of spinal cord injury.
The vertebral venous plexus is a network of valveless veins located within the vertebral column, facilitating venous drainage from the spinal cord and surrounding structures. Its valveless nature allows bidirectional blood flow, which can be significant in the spread of infections or metastases within the body.
Central nervous system homeostasis refers to the dynamic balance maintained within the brain and spinal cord to ensure optimal functioning and response to internal and external stimuli. This involves intricate regulation of neurotransmitter levels, ion concentrations, and blood-brain barrier integrity to maintain a stable environment for neuronal activity.
Cerebrospinal fluid leak repair is a surgical procedure aimed at sealing leaks in the dura mater to prevent the escape of cerebrospinal fluid, which can lead to complications such as meningitis or brain herniation. The procedure often involves techniques like direct suturing, grafting, or the use of sealants to ensure a watertight closure and restore normal cerebrospinal fluid dynamics.
Cerebrospinal fluid drainage is a medical procedure used to alleviate pressure or remove excess fluid from the brain and spinal cord, often performed to treat conditions like hydrocephalus or to relieve intracranial pressure. This procedure can be life-saving and is typically conducted using a shunt system or external ventricular drain to ensure proper cerebrospinal fluid flow and pressure regulation.
The Primary Respiratory Mechanism (PRM) is a fundamental concept in osteopathy that describes the inherent rhythmic motion within the craniosacral system, which is believed to influence overall health and well-being. It encompasses the interaction of the central nervous system, cerebrospinal fluid, and cranial bones, promoting self-regulation and healing processes in the body.
Ischemia of the spinal cord occurs when blood flow to the spinal cord is reduced, leading to insufficient oxygen and nutrient supply, which can cause tissue damage and impair spinal cord function. This condition can result from various causes, including arterial blockage, trauma, or systemic hypotension, and may lead to significant neurological deficits depending on the severity and duration of the ischemia.
Ventricular dilation refers to the enlargement of the ventricles in the brain, which can be a sign of various neurological conditions, including hydrocephalus and neurodegenerative diseases. This condition is often detected through imaging techniques and can lead to increased intracranial pressure, affecting brain function.
