Choroid plexus is the name for a plexus of veins located in the cavity system of the brain. The plexus is important for the production of cerebrospinal fluid. What is the choroid plexus? The choroid plexus is a branching plexus of veins in the ventricle (cavity system) of the human brain. It is also known … Choroid Plexus: Structure, Function & Diseases
Neuroscience deals with the structure, function and disorders of nerves. These are thereby considered from a medical, biological as well as psychological point of view. In addition to the individual elements, the focus is primarily on complex nervous systems and the cooperation of the structures as well as complaints resulting from diseases. What are the … Neuroscience: Treatment, Effects & Risks
Gray matter is an important component of the central nervous system and significantly determines its functions. The brain‘s intelligence performance is particularly associated with the gray matter. However, in addition to intelligence, it controls all perceptual processes and motor performance in humans. What is gray matter? The central nervous system is composed of both gray … Gray Matter: Structure, Function & Diseases
Myelin sheath is the term used to describe the covering of the neurites of a nerve cell, which can be up to one meter long. The myelin sheath protects the nerve fiber, insulates it electrically, and allows much faster transmission speeds than nonmyelinated nerve fibers. Myelin sheaths are composed of special lipids, phospholipids, and structural … Myelin Sheath: Structure, Function & Diseases
Myelogenesis is the medical term used to describe, first, embryonic spinal cord formation and, second, the formation of the medulla of all medullary nerves, which is carried out by oligodendroglia and Schwann cells. Both meanings of the term deal with developmental processes of the nervous system. Disorders of these developmental processes result in functional impairment … Myelogenesis: Function, Tasks, Role & Diseases
Oligodendrocytes belong to the glial cell group and are an intrinsic part of the central nervous system, along with astrocytes and neurons. As glial cells, they perform supportive functions for neurons. Some neurological diseases, such as multiple sclerosis, are caused by dysfunction of oligodendrocytes. What are oligodendrocytes? Oligodendrocytes are a special type of glial cells. … Oligodendrocytes: Structure, Function & Diseases
West Nile virus is found in tropical as well as temperate areas, is from the Flaviviridae family, and was discovered in 1937. The virus primarily infects birds. If the virus is transmitted to a human, the so-called West Nile fever develops, a disease that causes no symptoms in 80 percent of cases. However, in less … West Nile Virus: Infection, Transmission & Diseases
The auricular magnus nerve is a sensitive nerve of the cervical plexus. The nerve supplies sensation to the dorsal ear skin and portions of the scalp. Damage to the nerve results in sensory disturbances. What is the auricular nerve magnus? The cervical nerve plexus is better known to medical professionals as the cervical plexus. It … Magnus Auricular Nerve: Structure, Function & Diseases
Epithelial-mesenchymal transition, or EMT, refers to the transformation of epithelial cells into mesenchymal cells. This transformation possesses great importance in embryonic development. However, this process also plays a key role in the development of metastases in carcinomas. What is epithelial-mesenchymal transition? Epithelial-mesenchymal transition is a conversion of already differentiated epithelial cells into undifferentiated mesenchymal stem … Epithelial-mesenchymal Transition: Function, Role & Diseases
By sleep pressure, medicine understands a regulatory circuit that regulates fatigue and triggers physically induced sleepiness. During periods of wakefulness, metabolic products are deposited in the brain, triggering swelling sleep pressure. During sleep, the glymphatic system cleanses the brain of these deposits. What is sleep pressure? In medicine, sleep pressure is a regulatory circuit that … Sleep Pressure: Function, Tasks, Role & Diseases
The suprascapular nerve innervates specific muscles of the shoulder region. The functions of the nerve are explained by its location and the way it transmits signals. Mechanical and biochemical nerve damage can lead to diseases and conditions explained in more detail below. What is the suprascapular nerve? The suprascapular nerve is a sensorimotor nerve. Colloquially, … Suprascapular Nerve: Structure, Function & Diseases
The septum pellucidum is located within the brain. It is a membrane that is functionally like a partition. It is located in the center of the two cerebral hemispheres. What is the septum pellucidum? The septum pellucidum is a small region in the front of the brain. It is located at the interface between the … Septum Pellucidum: Structure, Function & Diseases
