Neurulation Neurulation refers to the folding process in vertebrate embryos, which includes the transformation of the neural plate into the neural tube. The embryo at this stage is termed the neurula.rior to neurulation, during the migration of epiblastic endoderm cells towards the hypoblastic endoderm, the notochordal process opens into an arch termed the notochordal plate and attaches overlying neuroepithelium of the neural plate.

- Radiofrequency Ablation Radiofrequency ablation (RFA) also called rhizotomy or neurotomy is a novel non-surgical technique of treating pain. This technique employs radiofrequency waves to produce heat and the heat produced damage the nerves transmitting pain signal to the brain.

Neural Tube - Development and Stem Cells Embryonic Development of the Neural Tube: The neural tube is the embryonic structure that ultimately forms the brain and spinal cord. It is formed in a process called neurulation, in primary and secondary neurulation processes.In mice, primary neurulation prevails in the rostral sections of the embryo, while secondary neurulation occurs in the caudal section.mbryonic Development of the Neural Tube: The neural tube is the embryonic structure that ultimately forms the brain and spinal cord.

Radiofrequency Ablation Radiofrequency Ablation Radiofrequency ablation (RFA, also called Radiofrequency neurotomy or lesioning) is a minimally invasive procedure used to reduce facet joint pain in the back or neck. An electrical current produced by a radio wave is used to heat up a small area of nerve tissue, thereby decreasing the ability of those nerves to transmit pain signals from that specific area to the brain.

Degranulation Degranulation is a cellular process that releases antimicrobial cytotoxic or other molecules from secretory vesicles called granules found inside some cells. It is used by several different cells involved in the immune system, including granulocytes (neutrophils, basophils, and eosinophils) and mast cells. It is also used by certain lymphocytes such as natural killer (NK) cells and cytotoxic T cells, whose main purpose is to destroy invading microorganisms.

Neurulation Neurulation. the embryonic process in chordates and man by which the neural plate emerges and folds to form the neural tube. The embryo undergoing neurulation is said to be in the neurula stage.uring neurulation the rudiments of all the organ systems can be discerned in three germ layers. The external germ layer, or ectoderm, thickens on the dorsal side of the embryo and forms the neural plate; the neural folds arise along the edges of the neural plate.

Ablation In medicine, ablation is the same as removal of a part of biological tissue, usually by surgery. Surface ablation of the skin (dermabrasion, also called resurfacing because it induces regeneration) can be carried out by chemicals (which cause peeling) or by lasers.

- Hypergranulation or proud tissue is an overgrowth of granulation tissue above the height or border of the skin edge. It is unclear why this process actually happens in wounds. Hypergranulation tissue is usually friable and bleeds and must be dealt with.ngiogenesis is the process by which new blood vessels form, bringing in tiny capilarry buds that appear as granular tissue. Granulation tissue sets the stage for epithelial tissue to be laid down on top of the wound bed.

Ablation for Arrhythmias What is catheter ablation? Catheter ablation is a procedure that uses radiofrequency energy (similar to microwave heat) to destroy a small area of heart tissue that is causing rapid and irregular heartbeats. Destroying this tissue helps restore your heart’s regular rhythm. The procedure is also called radiofrequency ablation.

Ablation The term is often used in the context of laser ablation, a process in which a laser dissolves a material's molecular bonds. For a laser to ablate tissues, the power density or fluence must be high, otherwise thermocoagulation occurs, which is simply thermal vaporization of the tissues.

What is Cannulation? Cannulation. Cannulation is the process of inserting a tube (cannula) into a passage, duct or cavity to supply or withdraw material or data. In medical dictionary, cannulation is a process used to deliver or remove body fluids under various medical conditions, like withdrawing blood for sampling. Effective needle length is extended by half the length of the original needle in cannula by surrounding either the inner or outer surfaces of a trocar needle.

Digivolution Digivolution (進化, Shinka, lit. Evolution) is a term used in the Digimon series. It is a process used by Digimon, monsters that inhabit a parallel universe called the Digital World that spawned from Earth's telecommunications network. Through Digivolution, a Digimon can develop into a more powerful being.

Ablation Ablation. Ablation, also known as catheter ablation, is a treatment that aims to control or correct certain types of abnormally fast heart rhythms. An abnormal heart rhythm is known as an arrhythmia. An ablation is done using the same technique as an electrophysiology (EP) study and is often carried out at the same time. The EP study can discover if you have extra electrical pathways in your heart that could be causing your abnormally fast heart rhythm.

Urination Urination is the release of urine from the urinary bladder through the urethra to the urinary meatus outside of the body. It is also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including tinkling, peeing, weeing, and pissing.n healthy humans (and many other animals) the process of urination is under voluntary control. In infants, some elderly individuals, and those with neurological injury, urination may occur as an involuntary reflex.

Neurulation The neural plate folds in upon itself to form the neural tube, which will later differentiate into the spinal cord and the brain, eventually forming the central nervous system. Different portions of the neural tube form by two different processes, called primary and secondary neurulation, in different species. 1  In primary neurulation, the neural plate creases inward until the edges come in contact and fuse.
