"Ependymomas" Natural Recordings by Native Speakers
Ependymomas are a type of brain tumor that originate from the cells that line the lining of the brain's ventricles, known as ependymal cells. They can occur in various parts of the brain and spinal cord and account for about 10% of primary central nervous system tumors in children and adults.
Usage Examples for Ependymomas
Ependyma refers to the thin layer of cells lining the central canal of the spinal cord and the ventricles of the brain. Specifically, it is a type of glial cell that helps to produce cerebrospinal fluid, which surrounds and protects the central nervous system.
Ependymal refers to the cells or tissue lining the central canal of the spinal cord and the ventricles of the brain, which are responsible for the production and circulation of cerebrospinal fluid.
The ependymis is a type of epithelial tissue that forms the lining of the central canal of the spinal cord and the ventricles of the brain. It is a single layer of cuboidal cells that are contiguous with one another and produce cerebrospinal fluid (CSF).
An ependymoblast is a type of stem cell found in the central nervous system, particularly in the brain and spinal cord. These cells play a crucial role in the development of the neural tube, which eventually gives rise to the brain and spinal cord. Ependymoblasts are characterized by their ability to differentiate into various cell types, including neurons, glial cells, and ependymal cells. They are also capable of self-renewal, which allows them to maintain their stem cell properties and continue to proliferate.
An ependymocyte is a type of glial cell that is found in the central nervous system (CNS) of vertebrates, including humans. It is responsible for producing and maintaining the cerebrospinal fluid (CSF) that surrounds and protects the brain and spinal cord. Ependymocytes are found in the ependymal layer, which lines the ventricles of the brain and the central canal of the spinal cord. They produce CSF by actively pumping ions and water molecules across their cell membrane, creating a pressure gradient that drives the flow of CSF from the ventricles and central canal into the subarachnoid space surrounding the CNS.
Epenthesis is a linguistic phenomenon in which a sound or syllable is inserted into a word or phrase, often to improve its pronunciation or to follow a grammatical pattern. This can occur in various languages, including English, and is often used to create rhythm, stress, or clarity in speech. For example, the word "often" is often pronounced as "oft'n" to add a vowel sound, making it easier to pronounce.
Epenthesis (noun): The insertion of a sound or phonetic material into a word or phrase, often in a way that is phonetically natural or to improve ease of pronunciation. For example, the addition of a vowel sound between two consonants in a word, such as "strength" where the "th" sounds are separated by the vowel "e".
Epeolatry is a term referring to an excessive or undue love or admiration for words or language. It is often used to describe a tendency to be captivated by the sound, rhythm, or aesthetic appeal of words, rather than their actual meaning or utility.
An epernée is a decorative metal or glass frame, typically having a central compartment or vase, that is used to hold a bouquet of flowers or other decorations.
Epexegesis is a literary device that involves the interpretation or explanation of a word, phrase, or passage within the same text, often by repeating or paraphrasing the original phrase. It is used to clarify the meaning of a particular term or concept, and is commonly found in biblical and philosophical writing.
